Low-clearance bridge map
Tall RVs, fifth wheels, and box trucks can strike a low overpass or tunnel with disastrous results. DryRig maps 26,735 low-clearance points at or under 4.27 m (14 ft) across the US and Canada so you can route your rig around them.
Most low-clearance points by region
Each number is a count of mapped points at or under 4.27 m (14 ft). These are counts, not links to a state page.
This export has no per-state counts to show. Height rows were stored without a state, so they did not attach to these regions. The 26,735 points above are the national total at or under 4.27 m (14 ft).
How the data is sourced
Heights come from OpenStreetMap maxheight tags on bridges, tunnels, and signed
restrictions. A point is included when its parsed height is at or under 4.27 m (14 ft). That is the
same cutoff as the count on this page (max_height_m <= 4.27).
The upstream text is kept, so a sign reading "12'6"" is shown as posted.
