Having a commercial-grade GPS and proper vehicle profiling tools is essential to prevent costly bridge strikes. Here are our verified recommendations for drivers:
1. Garmin dēzl OTR710 Commercial GPS
Standard map apps route for passenger cars. This commercial unit allows you to profile your exact vehicle height, width, trailer length, and gross weight to avoid low bridges and restricted roadways.
Never guess your height. Account for secondary accessories, cargo boxes, and AC units physically. This heavy-duty fiberglass pole provides accurate clearance measurements up to 15 feet.
A dedicated commercial-grade navigator featuring specialized routing algorithms, real-time traffic updates, clean map views, and safety warnings for severe curves and low bridges.
Maximize stability under heavy loads. These air springs reduce sagging, improve ride leveling, and ensure your commercial rig maintains an optimal stance for highway bridge clearances.
Liability Disclaimer: Bridge clearances change due to road resurfacing, construction, settling, seasonal flooding, snow accumulation, and other factors that are not reflected in annual federal data releases. Posted clearance signs at the bridge itself always supersede any data shown here. CMBMV LLC, its officers, affiliates, and contributors shall not be held liable for any damages, losses, fines, injuries, accidents, cargo damage, vehicle damage, or any other consequence arising from the use of or reliance upon data presented on this website. This includes but is not limited to bridge strikes, over-height violations, route detours, delivery delays, or any direct, indirect, incidental, or consequential damages of any kind. By using this site, you acknowledge that you understand these limitations and agree that this data is a starting reference point only — not a substitute for on-the-ground verification, commercial routing software, or official DOT clearance postings.
Always verify bridge clearances in person before proceeding with any over-height or over-dimensional load. If in doubt, stop and measure.
