The proposed project consists of improving the local and regional circulation and reducing existing and future congestion by improving the Interstate 5 (I-5)/Louise Avenue Interchange. The interchange improvements are needed to enhance traffic operations and mobility, which will accommodate future traffic demands as a result of the growth planned for in the City of Lathrop’s General Plan. The proposed project would improve the existing compact diamond (Type L-1) interchange at I-5/Louise Avenue to accommodate the traffic associated with the growth planned in the City of Lathrop’s General Plan. Additionally, the project would include the following major project elements, widen the existing I-5 on- and off-ramps, reconstruct the undercrossing underneath the existing freeway bridge, construct I-5 ramp metering, provide new traffic signals, construct Class II bicycle lanes along Louise Avenue and new sidewalks along Louise Avenue. Caltrans is the lead agency under the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA).
