The Utah Department of Transportation declared as finished Wednesday a $59 million project that redesigned many intersections on Bangerter Highway.
It held a small community celebration to mark the finish at the corner of 7800 South, where a new freeway-type interchange was built.
The project also added two "continuous flow intersections" at 6200 South and 7000 South to eliminate separate left-turn signals there to help speed traffic flow.
The CFIs moved Bangerter's left-turn lanes back several hundred feet from the intersection.
Signals there allow vehicles to cross Bangerter into new, special far-left lanes to turn left onto the cross streets at the same time that through traffic on Bangerter goes straight through the intersection.
"These improvements on Bangerter Highway are vital to improving east-west traffic flow on the rapidly growing western side of the Salt Lake Valley," said Marwan Farah, UDOT Region 2 resident engineer.
In coordination with the project, UDOT is installing a pedestrian bridge at 8200 South and SR 111 Â reusing an old pedestrian bridge that was removed from Bangerter at 7800 South. The reused pedestrian bridge is scheduled to open to foot traffic in mid-September.
