SAN DIEGO — Caltrans has two major closures on State Route 163 and Interstate 8 through Mission Valley beginning Sunday night. The closures are for the SR-163 Friars Road Interchange Project and the Interstate 5/I-8 Improve the Move Project.

All lanes of northbound SR-163 between I-8 and Friars Road will close Sunday through Tuesday from 11:30 p.m. to 5 a.m.

All lanes of westbound I-8 between SR-163 and the Interstate 5 (I-5)/I-8 interchange will close Monday through Wednesday from 11 p.m. to 5 a.m.

  • Sunday: Only the northbound SR-163 closure
  • Monday: Both the northbound SR-163 closure and the westbound I-8 closure.
  • Tuesday: Both the northbound SR-163 closure and the westbound I-8 closure.
  • Wednesday: Only the westbound I-8 closure

Northbound SR-163 motorists will be detoured to eastbound I-8 to northbound I-805 to the merge at northbound SR-16.3

Westbound I-8 motorists will have a primary detour to southbound SR-163, continue on southbound SR-163 to northbound I-5, continue north on I-5 to eastbound I-8. Motorists can also detour using the westbound I-8 to southbound Interstate 805 ramp, to State Route 15, to westbound State Route 94 to northbound I-5, continue north on I-5 to eastbound I-8.

Drivers are reminded to ‘Be Work Zone Alert’ and to move over a lane if safe to do so and slow down when approaching Caltrans vehicles with amber flashing lights.

The $40 million SR-163 Friars Road Interchange Project includes widening the Friars Road overcrossing as well as improve the SR-163 on- and off-ramps. In addition, a southbound SR-163 auxiliary lane just north of the Friars Road off-ramp will be constructed.

The $22 million I-5/I-8 Improve the Move Project aims to reduce congestion on I-8 by constructing an additional westbound lane between Taylor Street and the interchange. The project also includes new signing to better direct motorists to regional recreation destinations, area universities, and to major employment centers in Downtown San Diego and Sorrento Valley.
