Construction Update – Week of May 7

Check out our latest video on the 15 Express Lanes, covering what happened last month, and what construction is coming up ahead.


The following I-15/State Route 60 connectors are scheduled to close consecutively Tuesday night, May 8, between 11 p.m. and 5 a.m. for shoulder strengthening work:

  • Northbound I-15 to Eastbound SR-60
  • Northbound I-15 to Westbound SR-60 loop ramp
  • Westbound SR-60 to Southbound I-15
  • Eastbound SR-60 to Southbound I-15

All the connectors will not be closed at the same time. All motorists will be detoured to northbound I-15, exit Jurupa Street, and return to southbound I-15. Motorists should follow posted detour signs.


Alternating nighttime lane closures are scheduled on northbound and southbound I-15 between Fourth St. and State Route 60. The closures are required for crews to continue sawcutting, strengthening the freeway shoulder, and restriping lanes.

At least one lane will remain open at all times. The lane closure schedule next week is as follows:

Construction Corner

A weekly series to explain common construction terms. 

Freeway Underpass/Overpass: An underpass refers to a roadway that crosses below a freeway. Vehicles use this road to pass under the freeway, as seen in the photo above. Conversely, an overpass refers to a roadway that crosses over a freeway.
