How is the clearance data verified?
1 of the 100 locations in Alabama is 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 4 were verified against a published source such as the facility's own website. The remaining 95 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.
