Road Closed to Thru Traffic

Road Closed to Thru Traffic signs were set up along CR1B by Exit 4 in North Sioux City and on Second Street in Jefferson Monday, April 19 for closure of the road to begin construction.

An asphalt overlay project began Monday, April 19 on CR1B, from Exit 4 (North Sioux City/McCook Lake) northwest to the City of Jefferson. That portion of CR1B is closed to through traffic while the contractor is milling asphalt off the roadway.

There will be heavy truck traffic on Military Road that runs parallel to I-29 on the east side between Exit 4 and the City of North Sioux City. The ground asphalt is being stockpiled on county property in that location.

Knife River is the construction company in charge of the project. This project will cost $2.9 million. Weather permitting, they have a completion date of May 29.
