SIOUX FALLS, S.D. – Starting Monday, Oct. 7, the South Dakota Department of Transportation will begin high surface friction treatment work on the Interstate 90 Exit 396 ramp to southbound Interstate 29.

Westbound traffic wanting exit southbound on I-29 will be detoured on I-229 southbound to I-29 southbound. 

The $1.3 million project will install a high friction surface treatment and durable pavement markings to various routes in the Sioux Falls Area including Interstate 90 westbound to the I-29 southbound on-ramp, I-29 northbound and southbound structures at mile marker 84.92 over the railroad, and the I- 29 structure over 12th Street.  

The prime contractor for this project is Louis-Company of Lees Summit, Missouri. 

The overall completion date for the project is Oct. 15, 2019.
