State Route 120 - McKinley Avenue Interchange Project
The SR 120 / McKinley Avenue Interchange Project is located along SR 120 between Yosemite Ave and Airport Avenue (PM 0.9/3.3) within the jurisdictional limits of both the City of Manteca and San Joaquin County. The financially constrained project will incorporate a spread diamond (Type L-2) interchange at McKinley Avenue while preserving the right of way for the originally approved partial cloverleaf (Type L-9) interchange. The approved project alternative includes on- and off-ramps, two new ramp bridges, auxiliary lanes on SR 120, ramp metering, and roadway improvements on McKinley Avenue, including a 10-foot wide sidewalk with Class 2 bike lane on both sides of the roadway. In the project design phase, the traffic operations were evaluated to confirm the project’s on-ramps could be constructed in phases with the interior loop on-ramps constructed later. This change was documented in a Supplemental Project Report.
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.
