The Lower Sacramento Road Improvement Project was completed in May 2017. Improvements to the 2.5 miles between Eight Mile Road and Harney Lane include: two new lanes in each direction with 8-foot wide shoulders and bike routes, a raised concrete median, a new traffic signal at Mettler Road, and modifications to an existing traffic signal at Armstrong Road. Also, overhead utilities were converted to underground to enhance safety and overall aesthetic. 

A ribbon cutting ceremony to celebrate the project's completion was held on Monday, September 25, 2017 on the northwest corner of Lower Sacramento Road and Armstrong Road. The project began in October 2014 and was completed five months ahead of schedule, with no injuries or accidents. 

The San Joaquin County Public Works Department won the 2017 American Public Works Association Project of the Year Award, presented during an August 4, 2017 ceremony, in the transportation and roadway category. This award is provided to agencies who show excellence in administration, management, design, sustainability, construction, community relations, and teamwork. 

The $7.5 million project was funded through Measure K – the local half-cent transportation sales tax for San Joaquin County - and local Traffic Impact Mitigation Fees.

The State Route 4/Crosstown Freeway Ramp Extension Project in Stockton was completed in December 2016.  The $140 million project extends the Crosstown Freeway west, from Fresno Avenue to Navy Drive. The extension is carried on twin viaduct (bridge) structures that cross over Fresno Avenue creating a grade separation that no longer allows highway traffic to enter the residential neighborhood at Fresno Avenue. Navy Drive has been converted to a four-lane facility with auxiliary lanes and a partial interchange. This project will reduce truck traffic in residential neighborhoods, including the historic Boggs Tract, and improve traffic flow in an important area that connects the Port of Stockton with major transportation corridors.
