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.
