MaineDOT, ATRC and AVCOG have completed curb ramp inventories along all MaineDOT roadways in the ATRC and AVCOG region. Various geometric features such as curb ramp slope, width, etc. were categorized and used to assess the compliance of each ramp with Americans with Disabilities Act requirements. This data and a visual representation of ramp compliance is available on the MaineDOT Public Map Viewer.
