Underpass expected to delay traffic on S.R. 224

Residents should expect delays this weekend on State Road 224 near Redstone Towne Center as crews’ tunnel under the four lanes of traffic to install a pedestrian underpass.

According to County Engineer Derek Radke, construction crews have been working for the past two weeks on the edge of the road shifting water lines and utilities.

The next phase of the project, which begins Friday at 6 p.m., will result in only one lane being open in each direction through Monday morning.

"Beginning Friday night, construction crews will tunnel under the road and install the pre-built pedestrian tunnel," said Snyderville Basin Recreation public affairs manager Bonnie Park.

To go from one side of the road to the other, a total of 178 feet of tunnel, is expected to be done in 60 hours, according to Park. All four lanes of traffic should be open again on Monday.

"We are recommending people use State Road 248 to get into Park City from the Basin over the weekend," said Park. "The biggest issue we are expecting is people trying to reach the Olympic Park from Salt Lake."

The total cost of the project is not to exceed $1.26 million, according to Park. Of that, $898,895 is coming from developer contributions including the Redstone Development, Bear Hollow Development and the Boyer Research Park. The rest of the project is being funded by the trail and open space bond passed last November.

The underpass will connect the State Road 224 trail on the east with the yet-to-be completed Bear Hollow/Millennium trail on the west.

"The tunnel will be 24 feet wide, with 12 feet of concrete and a six-foot soft-surface shoulder on either side," said Park.

After the tunnel is in place Aug. 1, a gateway, signs and a monument will be installed prior to the expected Sept. 1 completion.

Drivers are asked to use caution in the construction zone this weekend and plan ahead for delays.
