Streets in Sioux Falls
The Streets Division maintains and preserves Sioux Falls roadways. The team patches potholes, sweeps streets, removes snow in the winter, and extends the life of City road surfaces through preventive maintenance.
Big Picture: Streets in Sioux Falls
City crews maintain more than 900 miles of centerline streets across Sioux Falls, with about 10-15 more miles added each year. The South Dakota Department of Transportation maintains the three interstates that run through Sioux Falls (I-29, I-229, and I-90).
Road Surfaces
Most streets are paved with asphalt, while about 14% are concrete. Major arterial streets need a concrete surface to meet high traffic demands and heavy vehicles. Local and collector streets are usually covered with asphalt as a more cost-effective option that’s easier to repair.
Street Construction
The weather in South Dakota takes its toll on our streets, but our Streets team works year-round to maintain our roads to the best possible condition. Street construction season runs as many days as possible through Spring, Summer, and Fall. Our project teams provide general updates to residents via our website and social media.
Street Construction Projects
Street Maintenance
Our crews use a slurry seal to prevent damage and resurface asphalt roads through a process known as mill-and-overlay. Project areas are selected before each street construction season and posted online.
