Overview

The project is widening Loop 101 between 75th Avenue and I-17 by one general-purpose lane in each direction to improve traffic flow on Loop 101 and the cross streets. Other improvements 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.

This project is included in the Regional Transportation Plan for Maricopa County and is funded through Prop 400, a countywide dedicated half-cent sales tax for transportation improvements approved by voters in 2004.
