Airfield Safety Enhancement Program

TUS Runway to the Future

The Airfield Safety Enhancement (ASE) program will transition the airfield at Tucson International Airport (TUS) into a new era of safety and provide redundancy with a second parallel runway that will serve the Southern Arizona region for decades into the future.

ASE Program Is Four Projects

Estimated at $360 million (as of July 2022), the entire ASE program includes demolition of runway 11R/29L, a 75-foot wide by 8,000-foot long general aviation runway, and replace it with a new parallel runway that is 150-feet wide by 11,000 feet long, new taxiways and connector taxiways, installation of aircraft guidance systems and a modernization of the airfield geometry to meet current Federal Aviation Administration standards.

Construction has been divided into four projects – CMAR (Construction Manager at Risk) overseeing the new runway and taxiways; DBB1 (Design-Bid Build) of taxiways on the west side of the airfield; DBB2 expansion of the safety area southeast of the new runway; and DBB3 modernization of the existing commercial runway.
