Heavy traffic and delays are to be expected over the weekend while State Road 248 is reduced to one lane in each direction as a result of construction on two bridges near Quinn’s Junction.

The work to replace the concrete bridge decks for bridges over State Road 248, Richardson Flat Road and the Silver Creek interchange has been causing lengthy delays and traffic congestion on one of Park City’s main entry corridors during the morning and afternoon commutes. U.S. 40 has been reduced to one lane in each direction since May.

John Gleason, a public information officer with the Utah Department of Transportation, said in an email to The Park Record that the project is more than halfway done and on schedule to be finished by late August. Traffic is currently reduced to one lane in each direction in the westbound lanes while they work on the eastbound bridges.

“They are moving pretty well and a little faster than they thought they were,” Gleason said. “Everything is right on schedule.”

Construction crews recently completed hydro-demolition on the S.R. 248 Bridge, Gleason said. The process uses high-pressure water jets to destroy the top few inches of concrete on the bridge before a new surface is laid. While crews are pouring concrete, traffic on S.R. 248 will be reduced to one lane in each direction from approximately 6 a.m. to 4 p.m. today through Monday afternoon, Gleason said.

“Drivers should plan for delays during the morning and evening commute,” Gleason said. “These lane restrictions will allow crews to pour the concrete for the new bridge surface on U.S. 40 and complete other bridge work.

“Unfortunately, there really is not a great alternative for traffic around there,” Gleason said.

A little further south up the road, crews are scheduled to begin completing similar work on the Richardson Flat bridge, which will include hydro-demolition and resurfacing. Traffic is expected to be restricted with flaggers along Richardson Flat road while the work is completed, Gleason said.

Some of the other summer UDOT construction projects that are expected to cause traffic delays in the area are:

  • Interstate 80 culvert repair and resurfacing: I-80 is scheduled to be reduced to one lane in each direction from Castle Rock to the Wyoming border Monday through Thursday and again on Saturday. All eastbound lanes will remain open on Friday and all westbound lanes will be open on Sunday. This project is scheduled to be completed sometime in the fall.
  • I-80 concrete barriers: eastbound traffic along I-80 will also be reduced to one lane at the I-80/I-84 interchange near Echo for approximately three weeks while crews install new concrete safety barriers.
  • Mirror Lake Highway (State Road 150): drivers should expect at least 15 minute delays between mile markers 25 and 32 on July 14, 15 and 18.

“The goal is always to try and cut down on any of those delays, which is why we try and get the work done overnight at least,” Gleason said. “But we are also just asking people to allow extra time and we will finish up as quickly as we can.”
