Continuing its trend of building managed toll lanes with private-sector partners, the Texas Dept. of Transportation has "conditionally" awarded a team led by Kiewit Corp. an $847-million, 3.5-year design-build contract to expand and upgrade State Highway 183, also known as the Airport Freeway, in Dallas.

The award is "not set in stone," says Ryan LaFontaine, a TxDOT spokesperson. "There is a period where we'll go work with them to make sure their promises match what we require. Also, public hearings will be held. The process will last through the summer and into the fall."
