It is a major thoroughfare throughout the Wasatch Front as it runs north–south for 70.8 miles (113.9 km), linking US-6 near Elberta to US-89 in Woods Cross.

The route intersects several major freeways and highways in the Salt Lake City metropolitan area including I-215, I-80, and I-15.

The highway is also routed for a short distance along 500 South and 200 West in Bountiful and Camp Williams Road in Utah County.

SR-68 became a state highway in 1931, at which time the route ran from then–US-40 (North Temple Street) in Salt Lake City to present-day US-89 in Lehi.

In 1960, SR-68 switched alignments with SR-249 to follow Redwood Road and 2300 North to Bountiful; the route was extended south to Elberta at this time also.

[3] A four-way intersection in Elberta with US-6 marks the southern terminus of the route as it starts north on a two-lane undivided highway.

The route turns north near Utah Lake's northern shore, widening to two lanes each direction at the intersection with 400 South.

Shortly thereafter, the road passes Salt Lake Community College and enters West Valley City.

[7] West of Salt Lake City, the highway passes over the surplus canal of the Jordan River as it goes through the neighborhoods of Glendale and Poplar Grove.

Past an interchange at I-15, the route gains one passing lane and turns south onto 200 West, a two-lane undivided road.

It followed Redwood Road from US-40 (North Temple Street) south to the present SR-73 and then used SR-73 east to US-50/US-89/US-91 (now solely US-89) in Lehi.

[17] At the same time, SR-68 was extended south from the intersection with SR-73 around the west side of Utah Lake to US-6 at Elberta, with the portion east to Lehi becoming an extension of SR-73.

The road has been moved and extended multiple times, with the most recent change being in 2001 when SR-106 was deleted from the state highway system.
