Work to resume on I29 interchange next week

The Interstate 29/20th Street Interchange construction project from 22nd Avenue to 34th Avenue in Brookings is scheduled to resume on Monday April 10th.

Traffic control will be set up on I-29 for single lane closures of the northbound and southbound outside lanes to accommodate construction and connection to the interchange ramps.

Speed reduction of 65 mph will be in effect on I-29 through the single lane closure with a speed reduction to 45 mph when work is under way directly adjacent to the roadway.

Road closures are not anticipated during construction.

Final project completion is scheduled for July 14th.
