Road Construction Leads to Highway Closures

It’s road construction season again!  Work is scheduled to begin on Interstate 90 at Humboldt (exit 379) today (4/13). The contractor will begin tearing down the Interstate bridge over S.D. Highway 19. While this removal work is being completed, Highway 19 will be closed under I-90. The removal work will take approximately four days to complete.

Highway 19 is scheduled to be closed today and tomorrow. The contractor plans to reopen Highway 19 for the weekend and reclose it on Monday morning, April 17, 2023. The removal work is scheduled to be completed by Wednesday, April 19, 2023, and Highway 19 will be reopened to one lane.

The work to replace the existing bridge on I-90 at Humboldt (exit 379) will continue through the summer construction season. Traffic on Highway 19 will be reduced to one lane throughout the construction project. Stop signs will be in place at each end of the work zone to allow for the construction of the new bridge. Traffic will be required to take alternating turns traveling through the work zone.

Also today SD Highway 25 will be closing just north of DeSmet to the south SD Highway 28 junction for the planned construction.  This construction project includes grading, box culvert replacement & interim surfacing.  The project completion date is Nov 17, 2023.
