 |  Press Release

TUCSON, Ariz. (July 8, 2019) – Sundt Construction, Inc. and its joint venture partner Kiewit recently completed reconstruction of the Interstate 10 interchange at Ina Road in Tucson. InaInterchange

Since January 2017, the joint venture team has worked to elevate the Ina Road interchange, widen I-10 and Ina Road, and replace the existing Santa Cruz River Bridge. The improved infrastructure will help reduce delays and increase safety for the nearly 25,000 drivers who use the interchange every day.

The construction manager at risk project included reconstruction of the interchange at Ina Road as a precast concrete bridge overpass to I-10. It also included several street improvements, channel construction, drainage, retaining walls, signals, lighting, and utility relocation.

Of the various improvements made, the most notable is the bridge, which will take traffic over the Union Pacific Railroad tracks and break up delays on a heavily used four-lane road. Railroad crossings were previously at street level, causing frequent backups for daily drivers. Now drivers will have safer, faster access to and from the interstate.

Sundt opened its Tucson office in 1929. In the decades since, it has built notable landmarks across the Old Pueblo including nearly 60 buildings on the University of Arizona campus, the 4th Avenue Underpass and most recently the Banner-University Medical Center Tucson’s new tower. The company has three offices in Arizona: Tucson, Tempe and Phoenix.
