DAVIS COUNTY -- Davis County commuters may already know it, but new data released by the Utah Department of Transportation prove how much Legacy Parkway has affected the I-15 commute.
Transportation planner Eric Rasband says, "Prior to Legacy Parkway the commute took 31 percent longer than if cars were traveling at 65 miles per hour."
Now it's 12 percent less. Rasband says that shows Legacy took cars off I-15, but it also shows people are going faster than the speed limit.
"Unfortunately it does," he says. "That's a concern for the department and public safety as well."
Rasband says Legacy Parkway added about 25 to 30 percent capacity in the Davis county area.
