Caltrans To Perform Next Traffic Lane Shift As Interstate 5 Anchor Pavement And Rehabilitation Project Continues

Construction Stage 5 Traffic Shift To Be In Place From July 20 Through October 2025

San Joaquin County- The California Department of Transportation (Caltrans) will soon be shifting all traffic lanes on Interstate 5 (I-5) between Hammer Lane and Eight Mile Road in Stockton as construction progresses to Stage 5 of the I-5 Anchor Pavement and Rehabilitation Project.

The Stage 5 traffic shift will begin the week of July 20, 2025, and will see three traffic lanes on northbound and southbound I-5 remain open during daytime hours, with alternating lane closures overnight. The southbound #1 (left) lane will be shifted behind k-rail and crossed-over to the newly-paved northbound I-5 median lane, with the #2 (middle) and #3 (right) lanes open on the southbound mainline.

Northbound motorists will travel in the #2 (left), #3 (middle), and the newly-paved right shoulder lane. (See illustration above). This Stage 5 traffic shift is expected to be in place through October 2025.

Construction Stage 5 will see work being performed on the #1 (left) lane and left-hand median of southbound I-5 between Eight Mile Road and Hammer Lane in Stockton.

I-5 Anchor Project - Completed Work So Far:

Caltrans and the contractor, Bay Cities Paving and Grading Inc., have already completed:

• Stage 1 - Widening of the northbound and southbound median shoulders from 4 feet to 10 feet.
• Stage 2 - Paving of the northbound I-5 right-hand shoulders.
• Stage 3 - Removal of damaged concrete pavement and installation of new pavement on the #3 (right) lane and right-hand shoulder of southbound I-5 between Eight Mile Road and Hammer Lane in Stockton.
• Stage 4 - to be completed by July 20, 2025, will include roadway excavation of the existing #2 (middle) lane of southbound I-5 and placement of aggregate subbase and hot mix asphalt (HMA), followed by construction of Continously Reinforced Concrete Pavement (CRCP) on top of the HMA.

The above listed traffic shifts and lane/ramps closures are required as part of the I-5 Anchor Pavement Project that will improve 34 miles of existing pavement and shoulders from Hammer Lane in Stockton to the San Joaquin/ Sacramento County line. The project will also overlay on- and off-ramps with asphalt concrete at Eight Mile Road, SR-12, Turner Road, Peltier Road, and Thornton Road/Walnut Grove Road.
