Project Will Reduce Broadside Collisions & Improve Traffic Safety
Stockton – The California Department of Transportation (Caltrans) is preparing to begin the second phase of construction on the State Route 26 (SR-26)/State Route 49 Intersection Control Improvement Project in Calaveras County.
Work will include the construction of a single lane roundabout at the intersection of SR-26/49 along with the installation of closed-circuit television (CCTV) to help monitor live traffic conditions, evaluate roadway operations, and improve response time to traffic incidents. Temporary road closures with traffic detours will be required at various stages of construction for the safety of motorists, roadway workers, and equipment.
Beginning next week, crews will start the second phase of construction which includes a long-term full closure of SR-26 from Main Street to SR-49. The full closure of the SR-26/49 intersection (west side) will begin Monday, August 24, at 7:00 a.m. scheduled through Monday, November 9, 2026, at 7:00 a.m. Traffic detours will be in place along SR-12, SR-49, and Campo Seco Turnpike (local traffic) in addition to the existing temporary four-way intersection on SR-49 and Main Street.
Construction crews will primarily work day shifts from 6:00 a.m. to 5:00 p.m. The second phase of construction work is scheduled for approximately 55 working days (77 calendar days) - Mondays through Fridays - with completion expected in early November 2026. In addition to weekly traffic advisories and roadside message signs will be placed along the highway to alert motorists of scheduled lane closures.
This $4.5 million project was awarded to George Reed, Inc. (Modesto, CA), who will perform the work required. This project will improve traffic safety within the intersection by reducing the severity and number of broadside collisions caused by the failure of motorists to yield to traffic.
