McHenry Avenue Improvements
The McHenry Avenue Corridor Improvements project will enhance safety, inter-regional traffic circulation, and air quality. The improvements will include:
* 1.1 miles of widening along McHenry Avenue from 1,487 feet south of River Road to 190 feet south of Jones Road.
* Stanislaus River and SSJID Canal Bridges will be replaced with wider and safer bridges, satisfying current seismic design standards.
* Installation of a two-way left turn center lane to facilitate turns into and out of driveways on McHenry Avenue.
* Increased width of roadway shoulders to accommodate alternative travel modes, including bicyclists.
* Installation of a traffic signal on McHenry Avenue and River Road that will accommodate existing and future traffic demands.
The project was awarded on February 28th, 2017 to Myers & Sons Construction in the amount of $21,934,144.50. Funding for this project will be provided from the following programs:
- Federal Highway Bridge and Congestion Mitigation & Air Quality
- State Proposition 1B and Regional Surface Transportation
- Local Measure K Sales Tax

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

I-205 Lammers Road/Eleventh Street Interchange Project
Through the partnership of City of Tracy, the San Joaquin Council of Governments (SJCOG), and the California Department of Transportation (Caltrans) construction is being conducted to create a new interchange for Lammers Road at I-205. The west Tracy area is served by a partial directional interchange at Eleventh Street and a full interchange at Grant Line Road. No interchange currently serves Lammers Road at I-205. Without a new or modified interchange, traffic operations at Eleventh Street and Grant Line Road interchanges are expected to worsen over the next 20 years, as the Tracy community continues to grow to the north and west, in accordance with the adopted general plan.
Benefits from the project will include:
- Provide full access to both directions of I-205;
- Improve traffic operations at other interchanges, and;
- Accommodate estimated traffic growth.
The start date and end date of construction is still to be decided. Here is a brief review of the overall timeline for the project:
- January 2008 Environmental Studies Started
- Spring 2010 Draft Environmental Document released
- Spring 2010 Public Hearing
- Summer 2010 Public Review Period Closes – Comments Due
- Fall 2010 Final Environmental Document Approved
- 2010-2012 Final Design
- 2011-2013 Right of Way Acquisition
- T.B.D. Construct Interchange Modifications
The estimated total cost for the project is $86.1 million. Funding is broken down between four major sources:
- STIP : $20.0 million
- Measure K: $20.0 million
- Federal Re-authorization Program: $30.0 million
- Development Fees: $16.1 million
