7.5.2 Intersections and Driveways
Intersections and driveways are designed to clearly show pavement contours, profile grades, drainage, locations of sidewalks, pedestrian ramps, pavement structure, and limits of construction.
Frequent access points cause both operational and safety issues. Ensure the driveway spacing is as large as possible and shared access for neighboring facilities has been explored during project development, per TxDOT’s Access Management Manual (AMM). Tight spacing between driveways causes operational and safety issues which are exacerbated when multiple access points to one facility are present. Per the AMM, “as access density increases, crash rates increase”.
