A $1.6-billion project to revitalize the convergence of three major highways in Southern Tarrant County has been awarded to a joint-venture partnership of Kiewit Infrastructure South Co. and Austin Bridge & Road.

Mitigating impacts to day-trippers, commuters and truck drivers will challenge a Kiewit-Fann joint venture when it begins construction in 2022 on the high-volume 23-mile stretch of I-17 from Anthem Way to Sunset Point less than an hour north of Phoenix.

The city of Fountain wanted safer connectivity and traffic progression in a fast-growing part of town. As ground zero for a planned major residential development, the area also is a main route for both the school system and provides the only access to the regional landfill.

This freeway expansion project added a third travel lane in each direction along an eight-mile section of the toll road between Quincy Avenue and Interstate 70. 

The smoother, safer path afforded by the three-mile truck climbing lane and wider shoulders belies the unexpected challenges encountered during the three-year construction process.

The puzzle over how the fracture occurred, and how the bridge was still standing, remains as the bridge reopens.

Arkansas highway expansion overcomes a time-consuming triple culvert, weak soils, supplier slowdowns and even endangered mussels.

Navigating noise issues, congestion and even the religious concerns of three Jewish congregations in the area, construction crews are performing surgery on a major artery in metro Atlanta in the second-largest project ever for the Georgia Dept. of Transportation (GDOT).

The project, located on the city's north side, is expected to take six years to complete.
