The collapse of a stretch of road in Meade County could disrupt traffic in western South Dakota for months to come.
The New Underwood Road is a major north-south artery in the region, linking U.S. Highway 34 with Interstate 90. It's used heavily by trucks traveling to the oil fields, and is a popular route for residents of the Cheyenne Indian Reservation and northern counties who travel to Rapid City.
A portion of the paved road recently dropped 3 to 7 feet down the slope of a hill. Traffic is being detoured.
Highway Superintendent Ken McGirr says moving the road might be the only solution. But he says that would cost well over $1 million and won't happen this year.
