A contractor working for the City of Napa is now completing the replacement of the First Street Bridge over the Napa River just west of Silverado Trail. Work began in June 2008 and the street was reopened on August 1, 2009.
The photo shows the bridge in the early stages of demolition in July, 2008.
Project impacts will be included in the Traffic and Construction News webpage. Interested residents and businesspersons are encouraged to register via the website for the free City of Napa NewsWeekly email newsletter , which will include regular updates on the project.
During design of the Napa River Flood Protection Project, this bridge was identified as a blockage to flood water flows. It also suffered from age-related deterioration. After studies determined it was not feasible to rehabilitate or relocate the bridge, the City of Napa chose to replace it in support of the Flood Project.
The new bridge is 166 feet-10 inches long and 64 feet wide, and will accommodate a traffic lane, bicycle lane, vehicle barrier and sidewalk in each direction. To convey the needed amount of water for Flood Project specifications, the new bridge is about five feet higher than the existing bridge. The design by Engineer TY Lin International and Architect Donald MacDonald includes “state of the art” elements such as illuminated glass panels and lighted obelisk columns.
