Safety Tips
- Posted bridge heights may not account for recent road repaving, which can reduce actual clearance by several inches.
- Always allow at least 6 inches of clearance margin above your truck height.
- Remember to account for any equipment mounted on top of your cab (antennas, air horns, roof fairings).
- Tire pressure affects vehicle height — fully inflated tires sit about 1-2 inches higher than underinflated ones.
- If in doubt, find an alternate route. A bridge strike can cause thousands in damage and criminal charges.
