I-29 reconstruction to begin; Exit 15 at Elk Point to close
Work is scheduled to start next week on the reconstruction of the northbound lanes of I-29 from one-half mile north of Exit 4 at McCook Lake to one mile south of Exit 18 at Elk Point.

On Monday, May 1, crews began building a temporary median crossover north of Exit 4 to re-route traffic during the major reconstruction of I-29.

The project consists of total removal of 13 miles of existing pavement and shoulders, reworking the underlying grade and placing new reinforced concrete pavement with asphalt shoulders. "Weigh-In-Motion" sensors will also be installed in the pavement south of the new Port of Entry to provide advance weight screening of the trucks approaching the Port.


Traffic will be maintained head-to-head in the southbound lanes during reconstruction. Temporary ramps will be built across the median to access Jefferson at Exit 9, and at the new Port of Entry facility.

Exit 15 at Elk Point will be closed throughout the project. Exit 9 at Jefferson will be closed for a maximum of 10 days during the placement of concrete across the temporary ramps. A detour on old Highway 77, or Union County Road 1B, will be used to access Jefferson during this 10-day closure period.

Fred Carlson Company of Sioux City, IA, is the prime contractor on the $11.7 million project. All work is expected to be completed by Oct. 13.
