36 CFR Part 1190, Proposed Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way; Shared Use Paths: Supplemental Notice of Proposed Rulemaking (SNPRM)

R210 Protruding Objects

The SNPRM would revise R210 to read as follows:

R210.1 General. Protruding objects shall comply with the applicable requirements in R210.

R210.2 Pedestrian Circulation Paths Other Than Shared Use Paths. Objects along or overhanging any portion of a pedestrian circulation path other than a shared use path shall comply with R402 and shall not reduce the clear width required for pedestrian access routes.

R210.3 Shared Use Paths. Objects shall not overhang or protrude into any portion of a shared use path at or below 2.4 m (8.0 ft) measured from the finish surface.

As proposed in the NPRM, R210 would require objects along or overhanging any portion of a pedestrian circulation path to comply with the proposed technical provisions for protruding objects in R402 and to not reduce the clear width required for pedestrian access routes.

The SNPRM would renumber R210 to include a general provision in R210.1 and a specific provision for pedestrian circulation paths other than shared use paths in R210.2 that would require objects along or overhanging any portion of the path to comply with the proposed technical provisions for protruding objects in R402 and to not reduce the clear width required for pedestrian access routes, as proposed in the NPRM.

The SNPRM would add a new provision for shared use paths at R210.3 that would prohibit objects from overhanging or protruding into any portion of a shared use path at or below 8 feet measured from the finish surface.

The proposed provision for shared used paths is consistent with the AASHTO Guide. The AASHTO Guide recommends 10 feet vertical clearance along shared use paths, and 8 feet minimum vertical clearance in constrained areas. The AASHTO Guide recommends that fixed objects should not be permitted to protrude within the vertical or horizontal clearance of a shared use path. See AASHTO Guide, 5.2.1 Width and Clearance.
