Some of the lanes will begin closing at 7 p.m. with all the lanes closing by 11 p.m. The closure will also include the eastbound and westbound I-8 connector ramps to northbound SR-163. The eastbound Friars Road on-ramp to northbound SR-163 will also be closed.
Caltrans says all southbound motorists will be rerouted to southbound I-805. Northbound travelers will be rerouted to eastbound I-8.
The closures will take place so crews can continue installing falsework on the Friars Road Bridge.
