Re: geometric design of pedestrain bridge

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If pedestrian accessible, then the American Disabilities Act
regulations are applicable, eventhough there are some communities which
choose not to enforce those regulations. The ADA specifies maximum
slopes (inclines), handrail heights, intermediate rails etc. The
information is available online. (I am a senior moment) Please go to and search for ADA or American Disabilities Act.
