Drivers, prepare for a major detour. Southbound Interstate 680 in Pleasanton is slated for a full shutdown starting from the I-580/I-680 connector to Koopman Road, beginning March 15 through to March 18. The closure announced by Caltrans kicks off at 9 p.m. Friday and is expected to last until 4 a.m. Monday morning, as officials told Caltrans.
This traffic-disrupting move is not without its benefits. The construction team will be hard at work replacing a section of the dated pavement with new material, promising motorists a safer and smoother journey. As per Caltrans, the extensive work over the weekend is set to expedite the road's refurbishment by a whole year, sparing drivers the ordeal of navigating through deteriorating conditions until 2025. If the plan unfolds without surprises, approximately 40 potential nighttime closures can be scratched off the calendar.
Caltrans has proposed alternative routes to navigate the closure for those fretting over the inconvenience. Westbound I-80 travelers from Vacaville and Fairfield must stay on I-80 to southbound I-880. Detours are also in place for commuters on the southbound I-680 corridor, with recommendations varying based on their approach — from going west on I-780 to I-80 for Benicia Bridge motorists to taking SR-24 to I-80 for those coming from Walnut Creek. Caltrans ' official announcement details a full list of detours and shutdown locations.
If the weather throws a curveball or unforeseen events crop up, the scheduled closure might get a rain check with advance notice to the public. Caltrans has arranged for portable changeable message signs to direct commuters before and during the closure, ensuring everyone can stay on top of the latest traffic developments. California Highway Patrol officers and message signs are deployed to facilitate detouring vehicles. Meanwhile, travelers heading north on I-680 won't be affected by the weekend's work and can proceed as usual.
For residents and local drivers in Pleasanton, it's worth noting that access to southbound I-680 is restricted in the city, with specified turns only allowed at southbound Foothill Road and southbound Pleasanton Sunol Road at Castlewood Drive. Caltrans has expressed gratitude for the public's patience before the construction, reinforcing their commitment to improving travel conditions on one of California's key highways.
