Sundt-Kiewit, a joint venture between Sundt Construction, Inc. and Kiewit Infrastructure West Co., has completed the Ina Road interchange in Marana, Arizona, near Tucson.
The companies broke ground on the project in 2017 to elevate the Ina Road interchange, widen both Interstate 10 and Ina Road and replace the Santa Cruz River bridge.
The standout feature of the improvements is a bridge that will allow traffic to flow over the Union Pacific Railroad tracks to reduce delays and improve safety for daily drivers. Other improvements consist of street improvements including: channel constructions, drainage, retaining walls, lighting and utility relocation.
