PROWAG (Public Right-of-Way Accessibility Guidelines) from the US Access Board have now been officially adopted. I’ve only begun to review them, but a few things grabbed my attention right off the bat. From PROWAG:

“At an intersection corner, one curb ramp or blended transition shall be provided for each crosswalk, or a single blended transition that spans all crosswalks at the intersection corner may be provided. Where pedestrian crossing is prohibited, curb ramps or blended transitions shall not be provided, and the pedestrian circulation path shall be either (a) separated from the roadway with landscaping or other non-prepared surface or (b) separated from the roadway by a detectable vertical edge treatment with a bottom edge 15 inches maximum above the pedestrian circulation path.”

This means that the diagonal access ramps at corners, which are common in suburban areas and even a few urban areas, are no longer legal for installation. For any alterations of curbs, sidewalk, or corner, new ramps must be two to a corner, perpendicular, or the ramp must cover the area of both sidewalks. See photo below.

Secondly, the pedestrian prohibition signing in common use in the City of Sacramento and many other places is now illegal, because it does not meet the criteria of the bottom edge no more than 15 inches above the sidewalk. See photo below, showing a newly installed curb ramp where the ramp does not extend the full width of both crosswalks. Again, any alteration of the curb, sidewalk, or corner requires compliant design. Of course the majority of these pedestrian crossing prohibitions are unnecessary, and were installed to ease motor vehicle traffic and not to protect walkers, so most should simply be removed, and legal curb ramps installed. The one exception would be freeway on and off ramps that have not been modified to be safe under any conditions.
