State and interstate highways are valid routes except for restrictions listed on the bridge embargo, detour and road embargo, and vertical clearance maps.
All systems permit county and city route maps
The detour and embargo map is updated every other week. The bridge embargo map is published whenever changes are needed. The vertical clearance maps, one for the interstate and one for the primary roads, are updated annually or as changes occur that are more restrictive.
Check with local officials when traveling on county roads or city streets for bridge embargo, detour, road embargo and vertical clearance information.Report a lost or broken link
