Learn more about the considerations for ensuring accessible, ADA-compliant crosswalks. Under Project Civic Access (PCA), the Civil Rights Division works with local governments nationwide to help them achieve compliance with Title II of the ADA and Section 504 of the Rehabilitation Act of 1973 (Section 504). The best way to determine if a curb ramp is accessible is to survey it to [§ 4.3.7], The ramp, or ramp run, must be at least 36 inches wide, not including the flared sides. These detectable warnings typically take the form of a tactile pad with small “truncated” domes that are perceptible underfoot or with a cane. But. Consider a case where the streets and sidewalks in a small town were built pre-ADA and have not been altered since. Please contact the Streets Department ADA Coordinator at: [email protected] or 215-686-5511 if you have any questions regarding ADA Curb Ramps. A program access approach would require the town to install curb ramps at key pedestrian crossings. Often, in these circumstances, private (On a curb ramp, the cross slope is the slope perpendicular to [across] the direction of pedestrian travel on the ramp run.) Intersection Design to Accommodate Pedestrian Crosswalk Cross Slope I. To comply with ADA requirements, the curb ramps provided must meet specific standards for width, slope, cross slope, placement, and other features.3 In constructing facilities such as walkways and pedestrian crossings, state and local governments can choose between two sets of standards – the ADA Standards for Accessible Design (ADA Standards) and the Uniform Federal Accessibility Standards (UFAS).4 Both of these standards have been deemed to comply with the requirements of Title II.5 However, state and local governments cannot pick and choose between particular portions of the ADA Standards and UFAS as they construct or alter the pedestrian crossings on a street and the curb ramps that provide access to the adjacent sidewalks. ADA standards require that all curb ramps include features known as “detectable warnings,” which provide a physical alert to visually impaired pedestrians that they are about to enter a roadway. C.    Why are Curb Ramps at Pedestrian Crossings Required? ADA Designing Pedestrian Facilities for Accessibility Compliance ADA Compliance Training Training Keet . Curb ramps are a small but important part of making sidewalks, street crossings, and the other pedestrian routes that make up the public right-of-way accessible to people with disabilities. Carmanah Technologies Corp. 250 Bay Street Victoria, BC, Canada V9A 3K5. They must be integrated into the walking surface, and there are specific measurements for the size and spacing of the domes.13. Face of button parallel to crosswalk Mounted at 48” max (42” max used in MUTCD) Max 5 lbs pressure needed to activate Accessible Pedestrian Pushbuttons Sign & Arrow Sign adjacent to button –explains 81 10 28 C.F.R. Two parking spaces shall be permitted to share a common access aisle. Departures from particular requirements of either standard by the use of other methods are permitted when it is clearly evident that equivalent access is provided.6. 9 28 C.F.R.  Minimum width of the crosswalk is 6’. Greenways and Trails Program ADA Accessibility Guidelines 3 KEY REQUIREMENTS FOR AN ACCESSIBLE TRAIL (A lower standard, or exception, is allowed under certain conditions as noted.) However, they may be needed from a program access perspective for other reasons, such as providing access to other town facilities served by the parking garage or to the town’s business district. Many of these now-familiar advancements are a result of the Americans with Disabilities Act (ADA), which mandates that all public environments—including sidewalks and crosswalks—accommodate people with disabilities. Where a crosswalk provides access be sidewalks, curb ramps that meet ADA Accessibility Guidelines (ADAAG), MassHighway Construction Standards, and all requirements of the Massachusetts Architectural Board (521 CMR) must be provided at both ends of the crosswalk. One way to make curb ramps compliant with Title II of the ADA is to build them in accordance with the ADA Standards.7 Following are the key characteristics of an accessible curb ramp according to the ADA Standards: Perpendicular Curb Ramps in the ADA Standards: Flared Sides or Returned Curbs? without violating any of the requirements in the Special Provisions. On November 23, 2005, the Access Board published revised draft accessibility guidelines for public rights-of-way, which are available on its website at www.access-board.gov/prowac/index.htm. A ramp is a running slope steeper than 1:20, meaning for every inch of height change, there are at least 20 inches of route run. 7 The bracketed references in this section refer to the applicable sections of the ADA Standards www.fhwa.dot.gov/civilrights/ada_memo_clarificationa.htm, www.fhwa.dot.gov/environment/bikeped/prwaa.htm, www.fhwa.dot.gov/environment/bikeped/dwm.htm, www.access-board.gov/ufas/ufas-html/ufas.htm. Tactile arrow indicating the direction of travel on the crosswalk, and Proposed PROWAG also requires APS to meet requirements for Operable Parts found in PROWAG section R409. [§ 4.8.2], For curb ramps constructed after January 26, 1992 (post-ADA), the slope must be 8.33 percent (1:12) or less. ADA requirements are integrated into all Oregon Department of Transportation standard drawings, details, specifications and design manuals. If “x” is 48 inches or more, then the flared sides may slope up to 10 percent (1:10) but not more. Curb ramps must also be located wherever there are curbs or other barriers to entry at any designated pedestrian crosswalks that are located mid-block. This map condenses the basic accessibility requirements for a mid-block crosswalk with pedestrian pushbutton from the ADAAG, PROWAG and MUTCD standards, such as: “Alterations” are another category of construction under the ADA. Inlet The U.S. Department of Transportation (DOT), however, is encouraging the use of a different design for detectable warnings.15 Under this design, detectable warnings extend the whole width of the ramp, but cover only the two feet of the ramp closest to the street. The gutter is the roadway surface immediately next to the curb ramp that runs along the curb. “Questions and Answers About ADA/Section 504" (, a memorandum describing FHWA’s oversight role on federal accessibility requirements (, FHWA’s notice adopting the Access Board’s draft accessibility guidelines for the public right-of-way as currently recommended best practices (, FHWA’s memorandum on detectable warnings (, The ramp run has the least running slope possible. [§ 4.8.2]. ADA Curb Ramp designs must meet the current applicable design standards and are subject to Streets Department approval through the ADA Unit. The federal government has begun a rulemaking process to revise the accessibility requirements for public rights-of-way. This Chapter discusses the ADA requirements for curb ramps at pedestrian crossings that are currently enforced by the Division under PCA. To assist you, the next installment of this Tool Kit will include instructions on how developers (who are not bound by Title II’s requirements when acting on In many localities crosswalk marking is done in response to … How can you tell if a curb ramp is accessible? What are detectable warnings, why must they be provided, and where are they required? The requirements in the ADA Standards for curb ramps newly constructed post-ADA (construction commenced after January 26, 1992) can be found in § 4.7. D.    What Does Title II of the ADA Require with Respect to Curb Ramps at Pedestrian Crossings? Curb ramps must be located wherever there are curbs or other barriers to entry from a pedestrian walkway or sidewalk, including any intersection where it is legal for a pedestrian to cross the street, whether or not there is any designated crosswalk. All crosswalks within the project limits are ADA compliant. The town is evaluating where it needs to install curb ramps to comply with Title II requirements. The landing must be connected to the pedestrian access route. available on its website at www.fhwa.dot.gov/environment/bikeped/dwm.htm. 14 ADA Standards § 4.7.7. In developing these draft guidelines, the Access Board obtained recommendations from an Advisory Committee composed of representatives from disability organizations, public works departments, transportation and traffic engineering groups, the design and civil engineering professions, government agencies, and standards-setting bodies. Combined curb ramps are a combination of the perpendicular and parallel curb ramp designs. Where and when curb ramps are required depends on the location and the age of streets and sidewalks. What is the function of detectable warnings? G. What are Detectable Warnings, Why are They Required, and Where Must They be Provided? survey form for use in conducting your surveys. ADA requirements for curb ramps include: 1:12 maximum running slope, or one foot in elevation change for every 12 feet 1:48 cross slope 48-inch minimum ramp width A level landing at top of ramp A clear space at the bottom Cut-throughs should be Previously, pedestrian pushbuttons with all accessibility features had larger power requirements and needed larger solar crosswalk systems in order to operate sustainably. Since the town hall and its surrounding streets and sidewalks were built pre-ADA and have not since been altered, the town must install curb ramps in compliance with Title II’s program access requirements for pre-ADA facilities. their own behalf) have not provided the curb ramps at pedestrian Example: Installing Curb Ramps for Program Accessibility. The Curb Ramps survey form and instructions will It is also dangerous. 1Any “NO” answer means that location is ADA non-compliant and needs to be corrected before acceptance of the work, except as follows. The town is trying to figure out where to install curb ramps to provide access to the town hall. Section 1: ADA (Required) 1. Refer to Appendix No.1 for visual clarity. E.    What are the General Requirements for Curb Ramps in the ADA Standards for Accessible Design? This Chapter is an effort to ensure that public entities do not create barriers to access by omitting curb ramps while the broader debate on accessibility requirements for public rights-of-way moves forward. [§ 4.7.5; Fig. For more information, please review our, Rectangular Rapid Flashing Beacons (RRFBs), Public Rights of Way Accessibility Guidelines (PROWAG), Download the accessibility requirements map, Learn more about ADA-compliant pushbuttons, Grants in Washington State for School Zones Available Now, Mid-Block Crosswalk Accessibility Requirements Map, Building Crosswalks for Walkable Communities Video, 1:12 maximum running slope, or one foot in elevation change for every 12 feet, A clear space at the bottom outside of parallel travel lane, Extend at least 24 inches in the direction travel, Cover the full width of the curb ramp’s flush edge, Are placed at the back of curb or at grade break, Have truncated domes with a diameter of 0.9” at the bottom, a diameter of 0.4” at the top, and height of 0.2”, Have high visual contrast with surrounding surfaces, Be a minimum of 2 inches across in at least one dimension, Be operable with a force no greater that 3.5 pounds, A visual contrast with the background of at least 70%, An audible locator tone that informs pedestrians of the need to push a button and provides an audible cue to the location of the button, A visible and audible indicator that the button has been pressed, Between 1.5 and 6 feet from the edge of the curb, shoulder, or pavement, At a mounting height of approximately 3.5 feet, but no more than 4 feet, above the sidewalk, Face of pushbutton must be parallel to the crosswalk. In such circumstances, state and local governments must install curb ramps that provide accessibility to the maximum extent feasible.12 Before reaching a conclusion about technical infeasibility, state and local governments need to consider the extent to which physical or site constraints can be addressed by alternative curb ramp designs. What does Title II of the ADA require with respect to curb ramps at pedestrian crossings? The long opening must be positioned so that it is 3. The components of the most common type of perpendicular midblock curb ramp are labelled below. If curb ramps are not provided, these individuals are forced to make a difficult choice. Changes in level/elevation requirements: • Up to 6 mm (0.25 in)-can remain without beveling. They can either stay at home and not go to their chosen destination, or they can risk their personal safety by using their wheelchairs, scooters, or walkers to travel alongside cars and other vehicles in the streets. However, they are not necessarily required to do so. To allow people with disabilities to cross streets safely, state and local governments must provide curb ramps at pedestrian crossings and at public transportation stops where walkways intersect a curb. public entities to provide. Where and when must state and local governments provide accessible curb ramps? The burden of proving technical infeasibility lies with the state or local government that constructed it. § 35.151(c), I. PROWAG requires that these detectable warnings: Pedestrian pushbutton requirements can be found in the MUTCD and PROWAG.  Stop bar is at minimum 4’ from the crosswalk.  Crosswalk pavement marking is 6” white. The regulation implementing title II of the ADA was revised as recently as 2016. determine the extent to which it complies with ADA accessibility requirements. to survey curb ramps for compliance with the ADA Standards and a Curb Ramps Some intersections have curb ramps; most do not. The exception being where vehicles are boarded from sidewalks or street level, where platforms must b… The minimum width for an ADA-compliant sidewalk is 36 inches (3 feet), though sidewalks can be constructed wider than this. The Architectural and Transportation Barriers Compliance Board (Access Board) is developing new accessibility guidelines. Ramps or cut-through islands should be provided for marked or unmarked crosswalks at median (or frontage road) islands. public entities also receive the legal responsibility for installing ADA-compliant 8 28 C.F.R. This means removing any lift or gap of ¼ inch or more. located in Appendix 1, are keyed to the Curb Ramps survey form, which will be (On a curb ramp, the running slope is the slope in the direction of pedestrian travel on the ramp run.) S ltoith P. Skilton Local Programs Engineer FHWA – NJ Division 840 Bear Tavern Road Suite 310840 Bear Tavern Road Curb ramps are required at all crossings with a change in height greater to ½ inch to provide pedestrians in wheelchairs or with other mobility restrictions a gradual entrance and exit from the crosswalk. The 4. ramp or other uncurbed connection to the crosswalk so that pedestrians do not inadvertently travel into the street. compliance with these requirements. They'e most commonly installed by state and local transportation departments, but are also used in private areas that are open to the public like malls, theme parks, shopping centers, sports arenas and other similar … Detectable warnings are intended to function much like stop signs for pedestrians who are blind or have low vision. What follows are some of the top considerations for implementing accessible, ADA compliant crosswalks. The town should seek input from people with mobility disabilities regarding the other key locations where curb ramps need to be installed to provide program access. The Advisory Committee’s report is available on the Access Board’s website at www.access-board.gov/prowac/commrept/index.htm. Several measures to aid persons with disabilities may be applied at an intersection and to the entire sidewalk network. The They must be at least 48 inches long with 24-inch-long segments on either side beyond the flares. Title II of the ADA requires state and local governments to make pedestrian crossings accessible to people with disabilities by providing curb ramps.2 This. The ramp, or ramp run, is the sloped section that individuals who use wheelchairs travel up and down when transitioning between the street and the sidewalk. 13 ADA Standards § 4.29.2. The most common type of curb ramp is the perpendicular curb ramp, which intersects the curb at a 90-degree angle. they will not necessarily identify all problems. In the construction or alteration of roadways and walkways, this typically means that only one standard may be used for a particular construction or alteration project, and all features of that project typically must comply with the chosen standard. Parallel curb ramps run parallel to the curb and usually take up the whole width of the sidewalk. guidelines for crosswalk installation at a national level, some states and cities have developed their own. where to take measurements. DOT has deemed this departure from the ADA Standards to be permitted under Title II of the ADA.16 An example of a curb ramp that complies with the DOT’s design can be seen on the right. Curb ramps must be placed to enable a person with a mobility disability to travel from a sidewalk on one side of the street, over or through any curbs or traffic islands, to the sidewalk on the other side of the street. ADA Requirements The Americans with Disabilities Act (ADA) of 1990 prohibits States and other public entities from discriminating on the basis of disability in the entities' services, programs, or activities. If the accessible route crosses traffic lanes, it shall be visibly marked to enhance pedestrian safety. But they are just one part. The most recent PROWAG proposed accessibility guidelines require all new and altered pedestrian signals to include the following features: The MUTCD also provides additional guidance on the location of pushbuttons, including: There are a number of other considerations that are not covered by this article, including crosswalk marking materials (X02.5.4.4) , extended crossing times (X02.5.5), and medians and pedestrian refuge islands (X02.5.6)—enhancements that benefit not only people with disabilities but everyone looking to get to and from their destination safely. Baseline requirements are laid out in the Public Rights of Way Accessibility Guidelines (PROWAG), however many state and local governments have developed more stringent standards that should be referenced before undertaking a project. Slope requirements for bus stop boarding and alighting areas, as with rail platforms, must be perpendicular to the roadway and not steeper than 1:48. In the meantime, many state and local governments will construct and alter highways, streets, roads, sidewalks, and pedestrian crossings. The accessible entrance to the town hall is located on North Street, which is on the north side of the building. Title II of the ADA requires state and local governments to make pedestrian crossings accessible to people with disabilities by providing curb ramps.2 This requirement applies if your state or local government has responsibility or authority over highways, streets, roads, pedestrian crossings, or walkways. However, the ramp must still transition at the bottom into the street inside the marked crossings for both crosswalks. [§ 4.1.6(3)(a)(ii)], The cross slope of the ramp run itself may not exceed 2 percent (1:50). “Pre-ADA” streets, sidewalks, roads, and highways are those that were built before January 26, 1992, and have not since been altered. By now, most of us have probably encountered an example of a pedestrian accessibility enhancement in our neighborhoods. F.    What are Pedestrian Crossings and Where Must Curb Ramps be Provided? 16 28 C.F.R. Avoid using accessible routes behind parked vehicles. instructions will also include photographs and illustrations showing how and Enacted by the U.S. Congress in 1990, the Americans with Disabilities Act (ADA)made it illegal to discriminate against persons with disabilities. When these facilities are deeded over to them, In this instance, installing curb ramps at the pedestrian crossings on the south side of the townhall are not needed from a program access perspective to enable people with disabilities to access the town hall. Revised ADA Standards for Accessible Design (2010 Standards) were issued on September 15, 2010 and went into effect on March 15, 2012. Whether it’s a curb ramp or an audible countdown timer, these engineering and technological advancements function to make pedestrian facilities usable by people of all ages and capabilities. On March 15, 2012, compliance with the 2010 Standards was required for new construction and alterations under Titles II and III . Under the ADA Standards, curb ramps are required to have detectable warnings that extend the full width and depth of the curb ramp.14 An example of a perpendicular curb ramp that complies with this requirement can be seen to the left. The parking garage that serves the town hall is located on North Street, directly across the street from the town hall’s accessible entrance. www.access-board.gov/prowac/commrept/index.htm. § 35.151(a). § 35.151(b). When pre-ADA streets or sidewalks are altered, there may be space limitations that restrict how much they can be altered to install accessible curb ramps. curb ramps which previously may not have existed. In addition, the requirements vary depending on the age of a highway, road, street, or sidewalk, and depending on when and whether it was paved, repaved, resurfaced beyond normal maintenance, or otherwise altered. [§ 4.7.2], The gutter must have a slope of no more than 5 percent (1:20) toward the ramp. In general, if it takes a person more than 3 minutes to walk to a crosswalk… Under a more flexible standard called “program access,” alternative routes to buildings may be acceptable where people with disabilities must travel only a marginally longer route than the general public. If sidewalks are less than 60 inches (5 feet) across, passing spaces must be constructed at set intervals. The new guidelines will cover pedestrian access to sidewalks and streets, including crosswalks, curb ramps, street furnishings, pedestrian signals, parking, and other parts of the public right-of-way. ½” maximum grate openings or horizontal gaps. requirement applies if your state or local government has responsibility or authority over highways, streets, roads, pedestrian crossings, or … [§ 4.7.7], Transitions from the ramp to the walkway, gutter, and street must be flush (level) and free of abrupt level changes. help you identify the most common accessibility problems with curb ramps, but Generally, you must provide curb ramps wherever a sidewalk or other pedestrian walkway crosses a curb. The ADA Standards require that curb ramps include features called “detectable warnings.” Detectable warnings consist of a series of small domes that contrast in color with the surrounding sidewalk or street. 15 DOT’s memorandum encouraging use of this alternate design for detectable warnings is What are some key characteristics of accessible curb ramps? If “x” is less than 48 inches, then the slope of the flared sides must be no more than 8.33 percent (1:12). Diagonal curb ramps can be used in place of two separate ramps for each crosswalk.
