Port of Los Angeles Closes Northbound SR 47 On/Off Ramps at Harbor Blvd. During Next Phase Construction of SR 47 Interchange

Jan. 23, 2026 – As construction of the SR 47 Interchange Project continues, the Port of Los Angeles announces the two older ramps at Harbor Blvd. will be closed to traffic for approximately seven months.

Starting at 10 p.m. tonight, crews will close the northbound SR 47 off-ramp at Harbor Blvd., also commonly referred to as the Harbor Blvd. off ramp from southbound I-110. Crews will close the northbound SR 47 on-ramp at 4 a.m. Saturday, Jan. 24. Both ramps will remain closed through Aug. 31.

The following detours are in place:

• DETOUR A: SB I-110 to Harbor Blvd.
  Exit at Channel Street/Pacific Avenue and continue to Front Street/Harbor Blvd.
• DETOUR B: Pacific Ave. to NB SR 47
  Take Pacific Avenue to Channel Street to SB I 110 to NB SR 47
• DETOUR C: Harbor Blvd. to NB SR 47
  Take Front Street/Harbor Blvd. to 1st Street to Gaffey Street to NB SR 47

Truckers should follow posted traffic signs and detours accordingly.

Those with questions may leave a message on the public phone line at (310) 732-7778. Calls will be returned within 24 hours.

The SR 47 Interchange Project is replacing the existing southbound SR 47 off-ramp from the Vincent Thomas Bridge with a new off-ramp on the north side. Additional improvements include realigning the existing on-ramp to the northbound I-110 connector; modifying the northbound SR 47 off-ramp onto Harbor Blvd.; modifying the northbound SR 47 on-ramp onto the bridge toward Terminal Island; and improving local streets near the interchange. The project is expected to be completed in December 2026.
