Critical Improvements Headed for the I-10 Corridor

PHOENIX, ARIZONA-- Drivers who use the congested Interstate-10 corridor south of Phoenix will soon breathe a sigh of relief, thanks to the passage of SB1239, sponsored by Sen. T.J. Shope (R-8).

Today, Governor Doug Ducey signed the landmark legislation that will appropriate $400 million from the state General Fund to the Arizona Department of Transportation to widen this important stretch of highway.

Over the next several years, construction is expected to begin in Casa Grande and move northward to Chandler, spanning approximately 25 miles. When complete, both the eastbound and westbound sides of I-10 will have three general purpose lanes for vehicles to use. Part of the stretch will also include extended HOV lanes. Furthermore, the funds will pay for on-ramps, off-ramps, interchanges, a frontage road, controlled-access highway improvements and safety upgrades to the Gila River Bridge.

"The expansion of the I-10 has been my biggest priority since I entered office 10 years ago. Historically, over half the population from Casa Grande alone is driving to the Phoenix Metro for work on a daily basis," said Sen. Shope. "During the winter season, the I-10 is generally the only east- west, coast-to-coast highway that is free of snow, allowing commerce to move from the ports in California and out to the rest of the United States. Unfortunately, this stretch of highway is notorious for terrible traffic jams during the morning and evening commutes and is frequently an area where deadly accidents happen. As Arizona's explosive growth continues, there's never been a greater need than now to upgrade this critical infrastructure."

With this $400 million state appropriation, ADOT is currently working to draw down federal matching monies to complete this project.

This legislation will take effect 90 days after the legislature adjourns.
