SR 120 - McKinley Avenue Interchange Project
The SR120 / McKinley Avenue Interchange Project is located along SR120 between Yosemite Ave and Airport Avenue (PM 2.2/3.2) within the jurisdictional limits of both the City of Manteca and San Joaquin County. The approved project alternative is a partial cloverleaf (Type L-9) interchange that includes on- and off-ramps, two new ramp bridges, auxiliary lanes on SR-120, ramp metering and roadway improvements on McKinley Avenue including a Class 1 bike path. In the project design phase the traffic operations are being evaluated to confirm the project’s on-ramps can be constructed in phases with the interior loop on-ramps constructed at a later date.
SR-120 serves traffic within the Manteca area an interregional traffic between the Central Valley and the Bay Area. The project will help to reduce congestion; improve traffic circulation; and enhance safety for motorists, bicyclists, and pedestrians.
The $46 million project was included in the Federal SAFETEA-LU bill as High Priority Program Project No. 1775, and received a federal earmark to help fund the planning and design. Right-of-way acquisition and construction will be funded by a combination of local, regional, and state funds.
