55-Hour Full Closures At Hammer Lane Off-Ramp, Eight Mile Road On-Ramp & Alternating Lane Closures On Southbound I-5 Scheduled For April 11-14, 2025

San Joaquin County – The California Department of Transportation (Caltrans) will perform 55-hour full ramp closures at Eight Mile Road and Hammer Lane on southbound Interstate 5 (I-5) as progress continues on the I-5 Anchor Pavement and Rehabilitation Project.

Closures of the Eight Mile Road on-ramp to southbound I-5 and the Hammer Lane off-ramp from southbound I-5 are scheduled to occur beginning at 10:00 p.m. on Friday, April 11, through 5:00 a.m. on Monday, April 14, 2025.

The following lane closures are also required to help expedite work and for the safety of workers and motorists:

• Overnight closures of the #2 (middle) and #3 (right) lanes of southbound I-5 from Eight Mile Road to Hammer Lane beginning Friday, April 11, through Monday, April 14, from 8:00 p.m. until 6:00 a.m.
• Daytime alternating closures the #2 (middle) and #3 (right) lanes of southbound I-5 from Eight Mile Road to Hammer Lane beginning Saturday, April 12, through Sunday, April 13, from 6:00 a.m. until 8:00 p.m.

Detour Information During 55-Hour Closures:

• Southbound I-5 Eight Mile Road on-ramp – motorists are advised to take Eight Mile Road to northbound I-5 to SR-12/Flag City to southbound I-5 during this closure.
• Southbound I-5 Hammer Lane off-ramp – motorists are advised to exit at Benjamin Holt Drive for access to local streets during this closure.

Closures of these ramps are required for excavation and removal of the existing roadway surface, followed by construction of new roadway surface and lane delineation (striping.)

Upon completion of these 55-hour ramp closures on April 14, 2025, a new traffic shift configuration will be implemented along the southbound I-5 Eight Mile Road/Hammer Lane corridor on April 15, 2025. Prior to the Eight Mile Road off-ramp, three lanes of southbound traffic will be split using the newly constructed #3 (right) lane, while the #2 (middle) lane will shift to the existing #1 (middle) lane behind k-rail (tunnel) and the #1 (left) crossed-over (tunnel) lane will remain in place. All three lanes on northbound and southbound I-5 will be open during daytime hours, with alternating lane closures occurring overnight. This traffic lane configuration is expected to be in place until August 4, 2025.

Work being performed during Stage 4 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 Continuously Reinforced Concrete Pavement (CRCP) on top of the HMA.

• Caltrans and the contractor, Bay Cities Paving and Grading Inc., have already completed Stage 1 that included 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 – Scheduled for completion on April 10, 2025, this stage includes the 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.

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.
