Project Description
The California Department of Transportation (Caltrans) will replace the northbound and southbound Stockton Channel Viaduct Bridges (Bridge Numbers 29-0176L and 29-0176R) in the City of Stockton on Interstate 5 from post miles 26.1 to 27.6.
Project Benefits
Purpose
The purpose of the project is to ensure the long-term serviceability and structural integrity and improve the permit load rating of the Stockton Channel Viaduct Bridges (Bridge Numbers 29-0176L and 29-0176R) on Interstate 5 in San Joaquin County.
Need
The project is needed because of structural deficiencies and continued bridge repairs. The bridges show concrete and steel superstructure/foundation deficiencies. The deficiencies include a long-standing issue of concrete deck deterioration resulting in ongoing maintenance challenges, freckled rust forming at various locations throughout the superstructure steel elements, damaged steel bracing, and cracking in the concrete retaining walls, bents, and columns. Substructure deficiencies, such as soil liquefaction potentially caused by seismic activity, are also prevalent. Additionally, the current structures are not rated to accommodate permit loading, which is required for goods movement.
