The Arizona Department of Transportation has initiated a study along a section of Loop 303 in the Northwest Valley to address how future growth in the region would impact the highway. The study will examine the benefits of adding a third general purpose lane in each direction between Happy Valley and Lake Pleasant parkways; constructing a new traffic interchange to tie in with the city of Peoria’s future extension of Jomax Road; and building a new bridge over the Beardsley Canal.
What to Expect:
During the construction phase, shoulder closures along the Loop 303 are anticipated and temporary single-lane closures might be necessary. ADOT would maintain at least one lane of travel in each direction while work is underway.
The study is scheduled to last 12 months.
Construction is scheduled to begin in fall 2019. Information about the duration of construction will be provided when a project schedule is confirmed.
