King Street over I-395Bridge repairs in the City of Alexandria
About the Project
The project will rehabilitate the King Street (Route 7) bridge over I-395. The bridge was constructed in 1970. The five-span structure carries six lanes of traffic, three in the eastbound direction and three in the westbound direction along with a median sidewalk. The total length of the bridge is approximately 410 feet. The bridge consists of concrete deck, steel superstructure, and concrete substructure.
The bridge is a candidate for federal funds for replacement.
Proposed repairs include the following:
- Installing An Impressed Current Cathodic Protection (ICCP) system with Latex Modified Concrete (LMC) overlay.
- Repair damaged concrete and install an ICCP system in the pier caps.
- Repair damaged column concrete and apply Electrochemical Chloride Extraction (ECE) treatment, and seal the treated surface with a breathable sealer.
- Repair damaged Abutment concrete, apply ECE treatment, and seal the treated surface with a breathable sealer
- Repair and paint all steel beams and replace bearings.
- Reconstruct the substandard bridge barrier/railing.
- Repair and/or replace guardrail, mill and overlay approaches.
- Minor pedestrian, bicycle and lighting improvements
- Repair roadway pavement and joints
The existing bridge has an average traffic count of 24,000 vehicles per day.
