Getting into and out of Chico from the north will be a major headache this weekend, as construction disrupts travel along State Route 99.
North and southbound traffic will be shunted onto a single lane across the short, Rock Creek Bridge, just north of Chico. Caltrans expects drivers to encounter up to 20-minute delays.
One-way traffic controls will be in place around the clock starting at 8 p.m. Friday. Caltrans is urging drivers to bypass the area if possible. Motorists can access Interstate 5 via State Route 32.
The highway along with a new, wider span featuring better sight lines is scheduled to open to traffic at 6 a.m. Monday, Aug. 14.
