Detectable Warning Surface

Dimensions: L varies (should extend across ramp or width of crossing), 2’W

A detectable warning surface communicates to people with visual impairments that they are entering or exiting a dedicated pedestrian space. Additional detectable warning surfaces can be used within quick build project areas to communicate new or relocated crossing locations, changes in street access, or other transitions between pedestrian-only spaces.
