He said the widening and the intersection work together are expected to cost $18 million, all paid by the county, not including the price of land. It's not yet clear how much land will be needed, so the cost is not yet clear.
Most of the land will be on the east side of U.S. 1, said Lafferty, including land owned by the state, which maintains the state police Waterloo barracks and a General Services Administration office along that stretch.
He said land will be set aside at the new Montevideo intersection on the east side for a new fire station to be built there eventually.
The road project is not expected to begin until the summer of 2014 and last about a year.
Love said there are no plans for detours or lane closures on U.S. 1 or Montevideo Road during construction. He said lanes may be narrowed temporarily from 12 feet to 11 feet, but otherwise the road is expected to remain open.
While that work is going on, the state plans to extend the right-turn lane from the southbound side of U.S. 1 onto Route 175 west, said Charlie Gischlar, spokesman for the State Highway Administration. He said it's not clear yet how long that extension will be or what it will cost, but it's clear that it's needed, as traffic tends to back up from that turning lane into the main road in peak travel times.
The extension, he said "will help everything."
