Multiple U.S. Regions Face Extensive Weekend Ramp and Lane Closures for Infrastructure Projects

Several states are announcing significant highway and ramp closures due to ongoing improvement and construction projects. In Arizona, northbound Loop 101 lanes and certain on-ramps will be closed for widening projects, with alternate routes suggested. Idaho's I-90 eastbound off-ramp at Cataldo will be closed for at least three weeks to facilitate bridge replacement and repaving ahead of winter, with detours in place. Florida's Pinellas County faces extensive lane closures on I-275, US 19, and other major roads with both nighttime and daytime work planned, urging drivers to seek alternate routes. Kentucky will have overnight ramp closures and intermittent lane closures around Louisville for striping operations. In California, the northbound US 101 ramps in San Luis Obispo will be closed for 10 days for safety improvements, with directional signage to guide drivers during this period.
