Two-year project to begin on Loop 101

If you drive the Loop 101 regularly, get ready for two and half years of construction.

Starting today, Arizona Department of Transportation officials are starting construction on an 11-mile long expansion of Loop 101.

The project will add one lane in each direction from Shea Boulevard to the Loop 202. 

"It's going to be a very busy project. The warning is, yes, we need the weekend closures. We will need overnight restriction along portions of the freeway and if you want to use alternate routes at certain times that might not be a bad idea," ADOT spokesperson Doug Nitzel says.

Nitzel says workers will first focus on expanding bridges along the route. From there, construction workers will replace overhead signs, add in new landscaping, and replace the existing road with quieter rubberized asphalt.

"During construction we are also going to have to move drivers over toward the center median wall so that crews can set up a barrier wall on the outside," said Nitzel.

The barrier wall will be used to protect workers during the construction process. The speed limit will also be lowered to 55 mph.

In addition to adding one lane in each direction in between Shea Boulevard and Loop 202, two extra lanes will be added near the Loop 101/202 interchange to ease traffic flow.

Right now more than 175,000 drivers use this section of the Loop 101 every day.

The project is expected to be finished in 2016.

Construction work starts tonight with road closures and restrictions near 90th Street.

  • Loop 101 northbound (Pima Freeway) will be closed overnight between 90th Street and Shea Boulevard from 10 p.m. Friday to 7 a.m. Saturday (Aug. 9). Detour: Northbound drivers can travel eastbound on 90th Street and then west onto Shea Boulevard.
  • Loop 101 (Pima Freeway) will be narrowed to two lanes in both directions between Shea Boulevard and Via De Ventura Drive from 10 p.m. Friday to 5 a.m. Monday (Aug. 11).​
