Interstate 5 North Stockton Interchanges and Widening Project
City of Stockton Department of Public Works
The Interstate 5 North Stockton Widening Project will accomplish four goals identified for the portion of I-5 through Stockton from the Highway 4 interchange to the North Gateway to Stockton just north of Eight Mile Road. The project will:
1) Widen I-5 from 6 to 8 lanes from Country Club Boulevard to Eight Mile Road;
2) Construct auxiliary lanes between interchanges;
3) Modify existing interchanges at I-5 and Hammer Lane and I-5 at Eight Mile Road; and
4) Construct two new interchanges at I-5 at Otto Drive and I-5 and the North Gateway.
The improvements for this project corridor will relieve existing and future congestion due to growth in the Stockton area. Kjeldsen, Sinnock & Neudeck, Inc., as a sub-consultant to Rajappan & Meyer Consulting Engineers Inc., provided essential services for the project, including all civil engineering to complete the off-roadway drainage design, acquisition of levee encroachment and flood control permits, and the right of way engineering surveys for acquisition at the new interchanges.
Phase 1 of the project addressed the widening and auxiliary lanes required from Country Club Boulevard to Hammer Lane. Due to the accelerated design schedule for Phase 1 of this project, extensive coordination between the design team and the City of Stockton, San Joaquin Council of Governments, and Caltrans was crucial to meet the completion deadline of the plans, specifications, and estimates in Fall 2010. Construction of the Phase 1 widening of I-5 may begin as early as 2011, pending availability of funds. Construction costs of Phase 1 are estimated at $220 Million.
