The project would widen the 15-mile stretch to six lanes with overpasses at FM 423, FM 720, Legacy Drive, Navo Road and Teel Parkway. TxDOT officials said the estimated construction cost is $140 million.
The last phase of the project widened the roadway from Lovers Lane to just west of CR 26, including frontage roads and overpasses at the Dallas North Tollway and Preston Road.
TxDOT progressing with US 380 alignment plan
A solution to alleviate congestion on US 380 in McKinney has yet to be identified.
TxDOT, which is overseeing the project, recommended a bypass alignment last May despite concerns raised by city and county officials. TxDOT's recommended alignment is estimated to cost $2.6 billion, according to documents. TxDOT officials said the US 380 project's feasibility study included an initial look at US 380 in Frisco, and more information will be available about impacts to the roadway in Frisco once the environmental study process is complete.
