MILFORD, Iowa (KTIV) -
It's going to cost big bucks to expand US Highway 20 to four lanes, statewide.
The 310 mile road touches Iowa's east and west borders. It's in a 50-year long process of changing from 2-lanes to 4-lanes. Officials say construction and funding are planned for the last remaining sections, except about 30 miles from Correctionville to Early.
Iowa Department of Transportation Commissioner Charese Yanney says it could cost around $200 million dollars. She thinks it'll be programmed into the budget incrementally and says it could take more than a decade to complete.
"Well let's see, it could be 2020, 2025. I hope it's not that long, but I don't know," said Yanney.
DOT officials recently announced a 26-mile stretch of Highway 20 is expected to open around Thanksgiving. It connects western Calhoun County to eastern Sac County.
