State Route 99/120 Interchange Connector Reconstruction

SJCOG, along with the California Department of Transportation (Caltrans) proposes to reconstruct the existing State Route (SR) 99 / State Route (SR) 120 interchange connector in the City of Manteca to provide congestion relief and improve operations. The purpose of this project is to improve the capacity and recurring traffic congestion of the eastbound to southbound and northbound to westbound connector ramps and eliminate weaving and merging issues between SR 99/120 and the SR 99 / Austin Road interchanges. Due to funding limitations the project has been separated into multiple construction phases:

Phase 1A: The first phase will provide capacity and operational improvements to the State Route 99/120 Connector by constructing a second lane on the connector from eastbound State Route 120 to southbound State Route 99 and constructing auxiliary lanes. These improvements will require the partial closure of the Austin Road / State Route 99 interchange and demolition of the existing Austin Road overcrossing to provide a new longer overcrossing structure that will accommodate the auxiliary lanes and provide a railroad grade separation over the Union Pacific Railroad Fresno Subdivision. The northbound off ramp and southbound on ramp at Austin Road will remain open. To preserve local road access to the modified interchange, a new alignment of Woodward Avenue to Austin Road with a connection to Moffat Blvd will be provided.

Phase 1B: The second phase of the project will construct a second lane on the northbound SR 99 to westbound SR 120 connector and extend an auxiliary lane on westbound SR 120 from SR 99 to Main Street.

Phase 1C: The third phase will restore full access to the Austin Road Interchange by adding braided ramps for the new Austin Road southbound off ramp and the northbound on ramp to SR 99. Phase 1C will also include adding a third eastbound lane on SR 120 between Main Street and SR 99, relocating the SR 99 Frontage Road, and adding additional auxiliary lanes on SR 99 between SR 120 and north of Olive Avenue.

Project Schedule

The project is currently in the Project Approval & Environmental Document (PA&ED) Phase. Following the completion of environmental clearance through the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA) the final design and right of way phases will begin for Phase 1A. Construction of Phase 1A is expected to to begin in the spring of 2023 and end in 2024.

Funding

The estimated total project cost for Phase 1A is approximately $45 million.

Miner Ave Complete Streets

The Miner Avenue Complete Streets Project is a 10-block rehabilitation of Miner Avenue from Center Street to the UPRR underpass, near the ACE Station. The project proposes the following improvements:

reducing lanes from four to two lanes and adding dedicated bicycle lanes, adding median islands and a roundabout at western end of the project corridor, modifying traffic signals at the intersections with traffic signals and streetlights, widening sidewalks with pedestrian and seating areas, and beautification. The project will build on and refine the Miner Avenue Streetscape Plan, adopted in 2011 to prepare a precise road plan with environmental documents that must be completed and approved before construction.

Public Information Meeting

An initial public information meeting was held in June 2016. Maps, information about the project, and other displays were presented, along with a brochure with tips and guidelines for drivers, bicyclists, pedestrians, and over-sized vehicles in roundabouts.

Funding

The estimated total cost for the project :This precise roadway plan portion of the project is funded by the Congestion Mitigation and Air Quality (CMAQ) Program via the Active Transportation Plan (ATP) Grant.

SR 120 Union Road Interchange

The City of Manteca (City), in cooperation with the City of Manteca Redevelopment Agency, the California Department of Transportation (Caltrans), and the San Joaquin Council of Governments (SJCOG), proposes to reconfigure the existing State Route (SR) 120/Union Road interchange to provide sufficient capacity to serve the project design year traffic volumes. A diverging diamond interchange configuration has been selected based on additional engineering analysis and environmental revalidation.

The purpose of the SR 120/Union Road interchange project is to:

Provide operational and safety improvements to address the anticipated traffic generated from ongoing local development and growth. Enhance circulation and mobility for vehicular traffic, bicycles, and pedestrians including a Class I bikeway.

The City of Manteca has identified within their General Plan the need for improvements to the SR 120/Union Road interchange to service projected growth in employment, residential units, and retail and commercial development on the south side of the SR 120 corridor. The interim signal project at the ramp intersections has temporarily improved the operations of the interchange, however the interchange is operating at unacceptable levels of service in the AM and PM peak hours with drivers experiencing long delays in the near-term.

Additionally, the existing interchange has no sidewalks or bike lanes. SR 120 serves as a significant barrier for north/south access for alternative modes of travel. The Project will include a Class I bikeway at Union Road across SR 120.

Current Status

Here is a brief review of the overall timeline for the project:

• City Advertised Project on December 10, 2018; Bid Opening Anticipated Jan 30, 2019
• Caltrans is completing Final PS&E Review and reviewing Utility Documents
• PG&E has been provided with Notice to Owner to Move 60KV Transmission Line; A Utility Policy Exception was approved on January 14, 2019

Funding

The City of Manteca is providing 100% funding for this project, using combination of Redevelopment Funds,  Measure K and other local funds.

Church Street Road Diet

The project will install Class II bike lanes and enhance pedestrian facilities and intersection crossings by reducing the existing traveled four-lanes to two-lanes on Church Street between Lodi Avenue and Lockeford Street in Lodi. Improvements will include replacement of damaged sidewalks, installation of accessible curb ramps with updated pedestrian push buttons, traffic signal improvements including separated left turn phases and pedestrians countdown heads, enhanced crosswalks and traffic signal video detection for bicyclists.

A road diet is a way to use existing roads, replacing excess car lanes with bicycle routes,  in a way that increases safety for all modes of transit and encouraging travel by means other than car.

These designs often used a parking lane as a barrier between vehicular traffic and cyclist and can be used to reduce traffic in busy pedestrian-heavy neighborhoods, both of which can drastically reduce crashes and injuries.

Funding

The project will cost an estimated $1.5 million, most of it coming from Measure K Bicycle, Pedestrian, and Safe Routes to School Program and the Smart Growth Incentive Program. The city will fund the remainder, about $60,000.

I-205 Managed Lanes 

Measure K is funding an environmental analysis of a project that will be years in the making — widening and other improvements to Interstate 205 providing easier, safer travel from the San Joaquin region to jobs, entertainment and recreation in the San Francisco Bay Area. Right now I-205 through Tracy sees heavy truck and commuter traffic and congestion. The analysis for the I-205 Manage Lanes project will look at possibly including carpool lanes, bus and/or passenger rail service in the median, and toll lanes, the first in the region. And depending on the ultimate plan, overpasses, underpasses and interchanges will be altered as needed. Up to four transit hubs could include park-and-ride lots, electric vehicle charging stations, and bus and train stops, making it easier for commuters and others to get around.
