TUCSON, Ariz. – Sundt-Kiewit, a joint venture between Sundt Construction, Inc. (www.sundt.com) and Kiewit Infrastructure West Co. (www.kiewit.com), has broken ground on the Interstate 10/Ina Road Traffic Interchange reconstruction in Tucson, Arizona.

The project aims to reduce traffic delays and increase safety by eliminating the existing at-grade crossing of Ina Road and the Union Pacific Railroad and building an overpass that takes Ina Road over I-10.

Work includes widening I-10 to four lanes in each direction and Ina Road to two lanes in each direction from Silverbell Road to Camino Martin. The team will also build two structures over the Santa Cruz River, and the eastbound and westbound frontage roads will be elevated to intersect with Ina Road’s new vertical alignment.

Expected to be completed in 2019, the project also features water and sewer relocations, grading and asphalt concrete placement, as well as new and expanded concrete box culverts and retaining walls, drainage facilities, traffic signals, signage, pavement markers, lighting, and landscape and irrigation along the interstate, frontage roads and Ina Road.
