Highway 100 project update

SIOUX FALLS, S.D. (KSFY) - The state has been in the process of conducting their largest construction project to date. The project costs nearly $55 million and will create a new interchange on I-90 in eastern Sioux Falls.

Last summer construction crews didn't have favorable conditions which ended up slowing the progress a little bit. But, crews have been out throughout the winter working on constructing a bridge that will go over BNSF Railroad and the Big Sioux River.

While construction on Veterans Parkway began two years ago, they are getting close to the final stages before I-90 is connected with eastern Sioux Falls.

There are three bridges from the Rice Street corner to the interchange for exit 402.

Beginning spring of 2019, they will begin working on the I-90 interchange, this will cause traffic along the interstate to become two-lane traffic and cause some delays.

Officials say once construction is complete they could possibly exceed 50,000 vehicles a day in some areas along Highway 100. Which show how busy eastern Sioux Falls can be.

"Rice Street right now is one of the main thoroughfares between Brandon and Sioux Falls it sees between 8,000 to 10,000 cars per day," Travis Dressen, South Dakota DOT, Sioux Falls engineer, said. "And also, as traffic comes into Sioux Falls those travelers are using I-229 and using some of the service interchanges along there. This will provide a new opportunity to exit 402 to connect to the east side of Sioux Falls where a lot of that development is happening now and is expected to happen into the future."

The interchange is expected to be completed in August of 2020.
