Another Traffic Shift for Sioux Falls Diverging Diamond Project
There's been another change to how you navigate a busy Sioux Falls road construction project.
According to the South Dakota Department of Transportation, beginning late today (June 9), traffic on the West 41st Street Bridge over Interstate 29 will be shifted to the south side as part of the ongoing Diverging Diamond Interchange construction project.
After the shift is complete, there will be one lane of traffic in each direction with a center turn lane.
In addition to the traffic shift on the 41st Street Bridge, the I-29 southbound on-ramp (Exit 77) at 41st Street will reopen Friday during the late afternoon or early evening.
This on-ramp has been closed for grading and paving work.
The work is all part of the 41st Street Diverging Diamond Interchange Project, which has been underway at the I-29 interchange since April of last year.
When it's completed by June of 2024, the new interchange will increase traffic flow in the area and reduce the number of accidents getting on and off the interstate.
The project's website describes a diverging diamond interchange as:
The DDI resembles a conventional diamond interchange. Drivers make right turns at a DDI just as they would at a regular diamond interchange. Drivers who want to turn left cross over to the left side of the road and then make their left turn. Because traffic is on the left side of the road between the crossover points, all left turns occur without having to cross opposing traffic.
