Locks/Bridges

Locks and Bridges with air draft:

The old standard for Air Draft (bridge clearance) was 50 feet and the new standard is 70 feet. There are some bridges that do not meet the standards or are some form of lift bridge that can be raised with adequate notice. Bridges across the main river channel listed as under 50′ air draft at normal pool stage are included below. Many bridges have air draft markings painted on the starboard hand bridge pier.
