Reminder: Eastbound Loop 101 closed from 75th to 51st avenues as construction begins on Loop 101 widening project

The Arizona Department of Transportation (ADOT) is set to begin construction of the Loop 101 (Agua Fria Freeway), 75th Avenue to I-17 widening project on Sept. 27. The project will add a new lane in each direction along Loop 101 west of I-17, and will take approximately two-and-a-half years to complete. Other project elements include widening bridges, modifying interchange ramps and frontage roads in some locations, adding a third southbound left turn lane onto Loop 101 at 75th Avenue, improving the system interchange ramp between westbound Loop 101 and northbound I-17 and resurfacing the roadway.

The work will require weekend and overnight closures of Loop 101 and the cross-streets, as well as 60-day closures of interchange ramps.

The following closures and restrictions are planned:

  • Eastbound Loop 101 on-ramps at Bell Road and Union Hills Drive
