How is the clearance data verified?
19 of the 1138 locations in Pennsylvania are AI-verified: the posted clearance was read directly from the entrance sign in Google Street View using Claude Vision (Anthropic's image AI), and we store the exact Street View pano so you can open it and check the sign yourself. Another 3 were verified against a published source such as the facility's own website. The remaining 1116 are imported from OpenStreetMap and the FHWA National Bridge Inventory and are not individually verified. Always confirm at the posted sign before you drive.
⚠ Always verify at the sign.
Posted clearances on this page are for planning. The only authoritative number
is the sign at the garage entrance or bridge approach. Clearances can change
