The northbound connector ramp from State Route 163 which leads to eastbound Interstate 8 will be closed Friday from 11 p.m. to 9 a.m. Saturday.
Caltrans said motorists will be able to directed toward a detour on SR-163 at the westbound Friars Road loop off-ramp. After taking that exit, motorists will be led onto the southbound SR-163 on-ramp to the eastbound I-8 connector ramp.
During the closure, crews will be adding safety upgrades to the roadway including placing high-friction surface treatments, adding reflective signs and improving drainage outlets. Caltrans expects the ramp improvements to be completed in the fall.
