Interstate 5 North Stockton Interchanges and Widening Project

The Interstate 5 North Stockton Interchanges and Widening 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 North Gateway.  The improvements for this project corridor will relieve existing and future traffic congestion due to growth in the Stockton area.  Kjeldsen, Sinnock & Neudeck, Inc., as a sub-consultant to Rajappan & Meyer Consulting Engineers, Inc., provided essential engineering and surveying services for the project, including all civil engineering to complete the off-roadway drainage design, acquisition of levee encroachment and flood control permits, 3D High Definition Scanning of existing bridge deck surfaces, and the right of way engineering at the new interchanges.  The aggressive schedule for Phase 1 of this project required extensive coordination between the design team and the City of Stockton, San Joaquin Council of Governments, and Caltrans.  All permits and approvals were obtained and all bid documents for this $220 million project were completed within a short 18 months.  The total cost for all phases of the project is projected to be in excess of $500 million.
