Sioux Falls - 60th Street N. over Interstate 229



Project Summary:

Located on the east side of Sioux Falls on 60th 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 on May 23, 2022, with an expected completion date of August 11, 2023.

Project Updates: 

Completed work: The contractor has completed the grading operations on the project.

Anticipated work to be completed in November 2022: Grading for the substructure is almost complete. Retaining walls on the west side of I229 are being installed. Work on the structure will continue throughout the winter with a substantial completion date to have the roadway open to traffic by June 2, 2023.


November 2022 Update: 
The Contractor has removed the existing 60th St N bridge over I-229 during nighttime demolition. All debris and excess material have been hauled off-site to allow for the construction of the new bridge. The inside lanes of I-229 in both directions have been reduced to one lane to allow the Contract enough space to maneuver in the median. With the barriers in place, the Contractor set up the bridge cranes responsible for lifting heavy bridge components.

Currently the Contractor is driving pile in the median and will complete the bent before moving to the construction of the abutments. The bent construction is expected to continue through the rest of November.

The lane reduction on I-229 in both directions will remain in place throughout the winter months with speed reduced to 55 mph. Motorists are encouraged to slow down and use caution, especially during inclement weather events.


October 2022 Update: 

The Contractor has removed most of the existing 60th St N bridge over I-229 during nighttime demolition. Currently the Contractor is removing the existing three bents remaining and shaping the newly graded berms.

The Contractor is expected to have the bridge completely removed and hauled off site in the next few weeks. By the end of the month, the Contractor is expected to begin construction of the new bridge. For this operation, the inside lanes in both directions will be closed on I-229 to allow the Contractor enough room for the construction of the new center bent.
