I-205/Mountain House Pkwy/International Pkwy Interchange


Project Description

The California Department of Transportation (Caltrans), in cooperation with the City of Tracy (City), proposes to improve the Interstate (I-) 205 at Mountain House/International Parkway Interchange (hereafter, I-205/Mountain House Parkway Interchange) between post miles 0.8 and 2.0 on I-205. Increased traffic demand due to existing commercial growth and planned future development in San Joaquin County is creating the need to improve the interchange. The project will convert the existing hybrid tight-diamond/loop interchange into a partial cloverleaf interchange (Type L-9).

Purpose: The purpose of this project is to reduce congestion resulting from ongoing and planned development of the Cordes Ranch Specific Plan and to improve local circulation.

Need: This project is needed to accommodate the increase in traffic demand projected as part of the planned development in the Cordes Ranch Specific Plan Area, elsewhere in the City of Tracy, Mountain House Community Services District (MHCSD), San Joaquin County, and neighboring counties.


Project Funding

The City of Tracy TIMF and RTIF funds are being used for the PA&ED and PS&E phases with additional TIMF and RTIF funds secured for the right-of-way and construction phases. The City will pursue SJCOG Measure K funds to complete funding for the right-of-way and construction phases. The City has also submitted a funding application for the Infrastructure For Rebuilding America (INFRA) and for Better Utilizing Investments to Leverage Development (BUILD).

The total cost of the project (Project Approval & Environmental Document, Plans, Specifications & Estimates, Right of Way, and Construction costs) is estimated at $52.9 million.
