Northbound I-5 reduced to one lane after overturned semi in Fresno County

Northbound Interstate 5 was down to one lane just north of State Route 145 in Fresno County after an overturned semi-truck blocked part of the roadway. Traffic backed up about 3 miles as Caltrans District 6 monitored the scene and warned drivers to expect delays through the corridor.

The lane restriction hit the northbound side of I-5 in the stretch just north of State Route 145, a key freight and commuter route through western Fresno County. Caltrans District 6 identified the crash location in that area and said the reduction to one lane remained in place because of the overturned semi-truck.

The backup stretched for roughly 3 miles, creating slowdowns for motorists moving through the rural freeway segment. Drivers heading north on I-5 had to move through the narrowed lane while crews monitored and worked to clear the scene.

Caltrans Central Valley District 6 also posted that the collision involved an overturned semi-truck and that the freeway was reduced to one lane in Fresno County. The district routinely uses live traffic alerts to flag major truck crashes and lane closures across the Central Valley, and this incident was handled the same way as other active freeway disruptions in the region.

I-5 is one of the region’s main north-south freight corridors, and even a single overturned truck can ripple quickly across traffic moving through Fresno County. With only one lane open northbound near State Route 145, delays were expected to continue until the crash scene could be fully cleared and the freeway reopened.

Caltrans had not announced a full reopening time in the posts tied to the incident. Drivers using I-5 through the area were left to contend with the lane drop and the resulting slow traffic until crews finished monitoring the site and restoring all lanes.
