Two new Loop 303 expansion projects to start soon in the West Valley

Construction work on Loop 303 expansion project

Loop 303 construction work near Greenway Road last year

We’ve followed along pretty closely as work on the Loop 303 has started to transform this two-lane freeway into a major transportation corridor for drivers in the West Valley…

First there was the 14-mile segment that opened a year ago – it stretches from Happy Valley Parkway to I-17.

Next, work started last summer on the six miles of freeway between Mountain View Boulevard and Peoria Avenue. Then, earlier this year crews began on the Loop 303/I-10 interchange.

Now we have two more projects to tell you about!

The Arizona State Transportation Board recently awarded contracts worth a total of $96.6 million for the additional sections of Loop 303 – stretching a total of five miles – between Thomas and Camelback roads and between Glendale and Peoria avenues.

That means that expansion work will soon be under way along nearly the entire length of the Loop 303 between I-10 and US 60 (Grand Avenue). We want to remind you to take precautions when driving through active work zones and prepare for a little extra travel time in case of delays.

Work on both of the new sections will begin next month. The two-mile segment between Thomas and Camelback roads is scheduled for completion by summer 2014. The three-mile stretch between Glendale and Peoria avenues will wrap up in fall 2014 and includes the construction of the Northern Parkway interchange and a one-mile section of Northern Parkway between Loop 303 and Sarival Avenue.

The sixth and final segment (between Camelback Road and Glendale Avenue) is scheduled to start this fall and be completed by fall 2014, under the Maricopa Association of Governments’ Regional Transportation Plan. We will, of course, tell you all about this portion of the project when work begins!
