The Michigan Department of Transportation has release a draft memo on Local Agency 3R guidelines to address changes in ADA requirements and how standards apply for a project with 3R and 4R work. LAP 3R Guidelines 2013 10-21 Draft

For the changes in ADA ramps, the following is a memo that FHWA and DOJ worked on jointly to address different interpretations of when ADA ramps are required for road projects that are considered alterations. The main change is Microsurfacing, Cape Seals and certain multiple CPM treatments will now be considered an alteration and will require ADA ramps to be upgraded.  For multiple CPM treatments, if more than one of those treatments contains aggregate and/or filler, the combination will be considered an alteration. 2013-07-30 – BRIEF – ADA Resurfacing Technical Assistance

For a project that includes 3R and 4R work, the applicable standards will correspond individually to each work type (3R or 4R) within the limits of that work.

FHWA has requested that MDOT implement the revised ADA requirements beginning with projects in the March 2014 bid letting. MDOT has requested that any comments or concerns be sent directly to Larry Doyle. He can be reached at [email protected].
