Locust Street Bridge Replacement

Locust Street over Des Moines River Bridge


The Locust Street Bridge, constructed in 1909, is the oldest concrete arch bridge in the Civic Center Historic District (CCHD). The bridge was rehabilitated in 1967 and is classified as a non-contributing structure of the CCHD (National Register of Historic Places (NRHP), 1988).Some Description

The structurally deficient, scour-critical bridge has experienced a significant increase in deterioration, resulting in main load-carrying members exhibiting significant concrete spalling, delamination, and section loss of exposed reinforcing steel. An in-depth structural review and a life-cycle cost analysis was performed yielding significant life-cycle cost savings for pursuing a full bridge replacement as opposed to a bridge rehabilitation. The proposed replacement bridge will be a concrete beam bridge, using modern design practices, to create a scour safe bridge with a design life of 100 years.
