BROOKINGS, S.D. – The Brookings 20th Street Interchange on Interstate 29 is scheduled to open on Saturday, July 29, 2023. Northbound and southbound I-29 on and off-ramps will be opened; as well as the 20th Street mainline through the city of Brookings.
Motorists should be aware that permanent signage installations along I-29 will continue over the coming weeks and may require periodic Interstate single-lane closures. A speed reduction of 65 mph through the work zone will remain in effect until all permanent signs are installed.
Motorists are also cautioned to be aware of crews wrapping up final inspection items within the project limits. These efforts are not anticipated to require a closure, but may result in personnel or equipment being adjacent to traffic.
The prime contractor for the $15.3 million dollar project is Bowes Construction, Inc. of Brookings, SD.
