How much did Interstate 11 cost to build?

Interstate 11 is the 54-mile (87 km) interstate in Nevada and Arizona linking Las Vegas toward Phoenix, whose only built part is the Boulder City Bypass south of Las Vegas, a two-phase project of the Nevada Department of Transportation and the Regional Transportation Commission of Southern Nevada, with Phase 1 upgrading 2.5 miles of US 93/95 at Railroad Pass for 83 million dollars and Phase 2 building a 12.5-mile loop south of Boulder City for 235 million, ending with a ribbon cutting on 9 August 2018. The Boulder City Review wrote in January 2018 that the project would cost 318 million dollars overall, with 249.2 million from federal funds.
