HMG-CN News Service

The bridge project will involve the replacement of the existing Firestone Boulevard Bridge in its entirety with a new bridge which meets current standards, with wider sidewalks, center median and shoulders.  

The same number of travel lanes (six) will be provided.  

The City of Norwalk is the lead agency on the project.  On March 4, 2014, the City of Norwalk City Council awarded a contract to Reyes Construction of Pomona in the amount of $7,586,493 for the construction of the bridge.  

Based on the bid received from Reyes Construction, the total estimated cost of the project, including construction engineering, contract administration and contingency, is approximately $9.5 million.  

The project will be funded through a federal grant, which will fund 88.53% of the project cost and a Proposition C discretionary grant received through the Los Angeles County Metropolitan Transportation Authority, which will fund the remaining 11.47% of the project cost.  

Construction is scheduled to commence in April 2014 and be completed by December 2015.
