They cost $216 million. But the four freewaylike interchanges added to Bangerter Highway last year have shortened afternoon peak-time commutes by eight minutes, new data say.
“That’s actually impressive because that still includes some big backups” daily at regular intersections with signals that tend to slow the flow between the new interchanges, said Brad Palmer, program manager for the Utah Department of Transportation’s Region 2.
UDOT traffic studies say that cut the afternoon commute on the highway between Interstate 80 near Salt Lake International Airport and Interstate 15 in Draper from an average 42 minutes to 34.
