Motorists in Salt Lake, Davis and surrounding counties have been champing at the bit for a chance to drive on the new Legacy Parkway.

Runners, walkers and bicyclists will get first crack at the fresh pavement, though, as the Utah Department of Transportation and the Hess Cancer Foundation will team up to host an early trip down the new road before motorized vehicles are allowed to bypass the bottleneck that is the I-15 corridor.

The Legacy Tour, a charity event benefiting the research and treatment of childhood cancer, will begin early Saturday morning with registration, music and vendors at the intersection of Center Street and the new Legacy Parkway in North Salt Lake.

A 20-mile bike ride — or race if you feel like getting a little speed on the new road — begins at 8:30 a.m., and a 5K or 10K run/walk follows at 9.

The new parkway will have bike, equestrian and foot trails over a 14-mile route designed to give the highway a nonhighway feel. But for the first morning, the pavement is off limits to engines.

Saturday's participants will receive a race T-shirt, food and other refreshments. Visit tourlegacy.com for registration information.

Drivers of cars, trucks and other motorized vehicles will get their shot to use the new road starting at 5 p.m. Saturday.
