Interstate 5 Matthews Road Intersection Improvements
Project Description
The proposed Mathews Rd Intersection Improvements project is located in French Camp, San Joaquin County, on I-5 at the Mathews Road interchange. The project proposes to install interconnected signals at four intersections, modify sidewalks to meet Americans with Disabilities Act (ADA) standards, and modify turn lanes to accommodate Surface Transportation Assistance Act (STAA) trucks and projected traffic volumes. Modifications will be performed at the following intersections:
- Two Northbound (NB) and Southbound (SB) ramp intersections at I-5/Mathews Rd
- Two County intersections at Mathews Rd/Manthey Rd and Mathews Rd/El Dorado St
Project Benefits
Purpose
The purpose of this project is to mitigate the traffic impacts associated with the development and opening of the Veterans Administration (VA) community-based outpatient clinic and living center in the French Camp area of San Joaquin County by signalizing the following intersections: Mathews Rd/Manthey Rd, Mathews Rd/I-5 SB Off-ramp, Mathews Rd/I-5 NB Off-ramp, and Mathews Rd/El Dorado St.
Need
Traffic Impact Study (TIS), completed by W-Trans on July 12, 2019, shows that the VA project would result in significant impacts at the following three intersections: Mathews Rd/Manthey Rd, Mathews Rd/I-5 SB Off-ramp, and Mathews Rd/I-5 NB Off-ramp. The impacts would significantly increase the queue lengths at the I-5 NB & SB Off-ramps, with queues projected to extend past the off-ramp gore point and onto the freeway mainline. In addition, the improvement of a fourth intersection at Mathews Rd/El Dorado St is necessary, due to its proximity and the need for it to be a part of the coordinated signal system to reduce queueing that would otherwise affect the overall traffic operations.
Funding Source
The project is sponsored by the Department of Veteran Affairs (VA) to address traffic mitigations in response to the new clinic in French Camp.
