I-5 - SB S Lucile St to Spring St - Pavement Repair - Closures & detour maps

What travelers should expect

The majority of this weather-dependent work will occur during the overnight hours when traffic is lighter. Travelers should anticipate lane and ramp closures beginning as early as 8 p.m. on weeknights and 9 p.m. on weekends. 

Throughout the summer, contractor crews may also close all lanes of the southbound I-5 mainline at night and shift traffic into the collector-distributor that parallels the main roadway. These shifts may occur between the hours of 10 p.m. and 4:30 a.m. on weeknights and 11 p.m. and 7 a.m. on weekends.

Changes to the south end of the collector-distributor 

  • The south end of the southbound I-5 collector-distributor (near the Edgar Martinez Drive/westbound I-90 on-ramps) is temporarily restriped to add a second lane for southbound traffic.
  • This temporary second lane will be open during the overnight hours when the southbound I-5 mainline is closed and traffic is shifted to the collector-distributor. 
  • The temporary second lane will use a portion of the Edgar Martinez Drive/westbound I-90 on-ramp merge lane.
  • Because of this, the Edgar Martinez Drive and westbound I-90 on-ramps to southbound I-5 will be closed when the temporary second lane is open.
  • The temporary second lane will be closed during non-working hours, while the on-ramps will be open.
  • This configuration will remain in place through the summer until the work is completed.
