Bridge Allowances

In coordination with the Federal Highway Administration, TDOT has specific standards for vertical clearance and weight limits on bridges across Tennessee. The vertical clerance of a bridge is the minimum height between the pavement and the bottom of the overhead structure. The weight limit refers to the maximum gross and axle weights for trucks and trailers allowable on the structure.

The materials provided on this page regarding vertical clearance and weight limits for Tennessee bridges are for informational purposes only. All forms are provided in Adobe PDF format.
