I-229 Construction Project in Sioux Falls Ready for Next Phase
The next round of work on Sioux Falls' latest Diverging Diamond Interchange is about to get underway.
Starting Monday (April 1), the South Dakota Department of Transportation will begin reconstruction work on Benson Road and the Interstate 229 interchange.
Benson Road will remain open to traffic as work begins on the south driving lanes from Casco Avenue to I-229. Traffic will be maintained on the north side of Benson Road. Access will be maintained to businesses throughout the project.
The $34 million project is reconstructing nearly two miles of Benson Road and about one mile of I-229 ramps. Work includes the construction of a Diverging Diamond Interchange (DDI), constructing a structure, grading, concrete surfacing, curb and gutter, storm sewer, lighting, signals, permanent signing, and pavement marking.
