Crews have been given the go-ahead from the Arizona Department of Transportation to transition from pre-construction to construction on the I-10 Broadway Curve project.

Crews have been boring and drilling to test soil conditions under the pavement; taking pavement inventory and doing repairs; and surveying and conducting utility relocations. They also removed the last section of rubberized asphalt between Hardy Drive and I-10 in Tempe.

The four-year project will bring improvements, additions and extra lanes to 11 miles on and around I-10, from the Loop 202—Santan/South Mountain Freewa—to I-17 near Phoenix Sky Harbor International Airport.

Crews also began removing glare screens along I-10 between 40th and 48th streets. Glare screens are the metal mesh that is mounted on median barrier walls to reduce glare from oncoming headlights.

Next, crews will begin increasing the height of the median barrier walls so they are tall enough and the glare screens are no longer necessary.

In the coming weeks, crews expect to begin setting up a nursery for native plant salvage operations. Mature specimens of plants that take many years to develop from seed, such as saguaros, barrel cactus, ocotillos and Palo Verde trees, are saved. They are cared for in a nursery until they can be returned to their permanent homes.

The work zone throughout the project area has been established. Barring an emergency, crews do not plan to fully close any freeways in the project area until 2022. However, some additional travel lane, ramp and road closures will be required this year.
