Traffic Delays Coming for Latest I-90 Diverging Diamond Project
The area's latest Diverging Diamond Interchange project is about to see a big change to traffic flow that will likely result in delays for the next few days.
Tuesday (July 16), the South Dakota Department of Transportation will begin use of a temporary signal for one-way traffic across the Exit Bridge on Highway 11 as it passes over Interstate 90 in Brandon.
Traffic at the bridge ends will be signaled to one lane. This one-way traffic diversion will be maintained until Friday (July 19).
The work is all part of a $41.3 million project that will reconstruct exit 406 (Brandon) with added lighting, signals, and mainline Interstate work.

This project also includes three structure replacements and will feature a Diverging Diamond Interchange.
Westbound I-90 lanes (along with the railroad structure on I-90) will be reconstructed in 2024 and the eastbound lanes in 2025.
The interchange and the new structure over I-90 will be reconstructed between the 2024 and 2025 construction seasons.
