Sioux Falls - 60th Street N. over Interstate 229

Project Summary:
Located on the east side of Sioux Falls on 60
th St. N, is a four-span prestressed bridge built in 1961 crosses over I229 just south of the I90/I229 interchange. The current bridge 50-221-170 has a 30ft wide roadway that carries two-way traffic over I229 with no sidewalks for pedestrians. Due to the expected increase in traffic volumes and the bridge nearing the end of its service life, a new bridge is scheduled to replace the existing one.
The new bridge will be able to accommodate a higher traffic volume in the future along with pedestrian needs and future growth. The new bridge will be a two-span steel girder bridge with a 40 ft wide roadway. This bridge will be constructed to accommodate two lanes of traffic as well as pedestrians with a sidewalk on the north side of the structure. The new structure will also be able to accommodate a bridge widening in the future to the south, along with an exit planned to connect I229 and 60th St. N.
Project Timeline:
The new bridge construction is planned to start May 23, 2022 with an expected completion date of August 11, 2023.
