Traffic Alerts - Loop 303: Happy Valley Parkway to Lake Pleasant Parkway

Loop 303 widening project completed in northwest Valley - Crews open interchange that connects to Peoria’s new Jomax Parkway

ADOT’s project to widen and make other improvements along Loop 303 in north Peoria was completed today.

As part of a $20.3 million project that started in Dec. 2020, Loop 303 has been widened from two to three lanes in each direction between Happy Valley and Lake Pleasant parkways.

ADOT’s work included today’s opening of the new Jomax Parkway interchange, which coincided with the city of Peoria’s completion of its separate project that added a section of Jomax Parkway between Vistancia Boulevard and the freeway. Construction of on- and off-ramps as part of the Jomax Parkway interchange combined with Peoria’s new roadway provides drivers with another option for local travel.

In addition to improving traffic capacity with the new lanes along the six mile stretch of Loop 303, crews on ADOT’s project constructed freeway bridges that drivers now use to travel over the Beardsley Canal and the Jomax Parkway interchange. Prior to the new bridges, drivers in those areas were traveling on interim sections of roadway to the outside of the freeway’s corridor.
