Major Delays Expected on I-15 this Weekend in Davis, Utah Counties

SALT LAKE CITY — The Utah Department of Transportation (UDOT) advises drivers to plan ahead for significant traffic restrictions on I-15 in Davis and Utah counties beginning as early as Saturday night. Crews will be demolishing a bridge at 400 North in Bountiful, and completing concrete pavement maintenance in Springville. Additional restrictions are also scheduled to begin on I-80 in Summit County as early as Saturday morning.

The following is a brief description of road construction projects that drivers should be aware of this weekend (all schedules subject to change due to weather or equipment issues):

I-15 in Davis County

I-15 is scheduled to close in both directions on Saturday, April 18, as early as 11 p.m. while crews demolish a bridge at 400 North in Bountiful. The freeway will be closed at the following locations:

  • Southbound I-15 will be closed between the Legacy Parkway/Park Lane interchange in Farmington and 400 North in Bountiful, and all southbound traffic will be diverted to Legacy Parkway. The southbound I-15 on-ramps at all interchanges in this area will also be closed.
  • Northbound I-15 will be closed at 400 North (Exit 317) in Bountiful. Northbound traffic will be diverted onto 400 North, then back onto the freeway via 500 West.

The freeway is scheduled to reopen by Sunday, April 19, at 11 a.m. Drivers in both directions are advised to use Legacy Parkway as an alternate route.

I-15 in Utah County

Southbound I-15 is scheduled to be reduced to one lane between 1400 North (Exit 261) and 400 South (Exit 260) in Springville on Saturday, April 18, as early as 9 p.m. for concrete pavement maintenance. These restrictions are scheduled to remain in place through Monday, April 20, at 7 a.m., when an additional lane will reopen.

During this time, drivers should plan ahead for severe traffic delays of more than an hour on Sunday, April 19, between 10 a.m. and 10 p.m. US-89 through Provo and Springville should be considered as an alternate route. In addition, UDOT recommends that drivers adjust their schedules to avoid travel on southbound I-15 during this time if possible.

Following these lane restrictions, the southbound lanes on I-15 in this area are scheduled to be split into two sections on Monday, April 20, as early as 12 p.m. This lane split is expected to remain in place through Thursday, April 23, at 5 a.m. to allow concrete pavement to cure. Drivers wanting to use exits 261 (1400 North) or 260 (400 South) in Springville will need to stay in the right lanes.

This work is being completed under warranty as part of the I-15 CORE project at no additional cost to taxpayers.

I-15 in Salt Lake County

Southbound I-15 is scheduled to be reduced to four lanes north of the 10600 South interchange beginning as early as Saturday, April 18, at 10 p.m. These restrictions are scheduled to remain in place through Sunday, April 19, at noon while crews complete concrete maintenance. This work is being completed at night to minimize traffic delays.

I-80 in Summit County

I-80 is scheduled to be reduced to one lane in each direction from the U.S. 40 interchange to Wanship as early as Saturday morning, April 18. All traffic will be shifted to the eastbound lanes, and the speed limit will be reduced to 45 miles per hour. In addition, the westbound on- and off-ramps at Exit 150 (Tollgate/Promontory) will both be closed. These restrictions are scheduled to remain in place through fall 2015.

Crews are completing the second phase of a project to reconstruct I-80 in this area with new concrete pavement. Last year, work was completed in the eastbound lanes, and this season crews are reconstructing the westbound lanes.

Construction schedules are weather-dependent and subject to change. For more information about these and other UDOT projects, visit udottraffic.utah.gov or download the UDOT Traffic app, available for iOS or Android devices.

First yellow flashing right turn arrow arrives in Utah

LEHI — Northern Utah County is developing at a rapid pace, emerging as a new frontier of the high-tech industry. In addition to retail attractions such as Cabela’s and the Outlets at Traverse Mountain, the area around I-15 at Timpanogos Highway (SR-92) has been dubbed the “Silicon Slopes,” attracting businesses who want affordable office space, a reliable talent pool from area universities and the high quality of life Utahns enjoy with a variety of outdoor recreation options just minutes away.

With all this development, UDOT continually evaluates how to improve traffic flow through the I-15/SR-92 interchange.

The latest update to the interchange is also a first in Utah: crews installed the state’s first flashing yellow right turn arrow at the northbound I-15 off-ramp to eastbound SR-92 in Lehi. You have probably driven through dozens of flashing yellow left turn arrows, where turning traffic yields but may make a left if there is no oncoming traffic. So why does the flashing yellow right turn arrow work at this interchange?

A flashing yellow arrow on a right hand turn on SR-92 allows traffic to flow more freely in a fast-growing part of Utah County.

A flashing yellow arrow on a right hand turn on SR-92 allows traffic to flow more freely in a fast-growing part of Utah County.

 

“The right turn goes into a lane that takes people to the SR-92 commuter lane, but a lot of people want to make a left into Adobe or Cabela’s,” said UDOT Region Three Signal Engineer Adam Lough. “We were seeing traffic back up and drivers getting frustrated because people who wanted to cross traffic to get to the left lane would be stopped on a green light. The flashing yellow signals a yield condition for drivers who want to move to the left lane on SR-92 as well as for the queue of traffic on the ramp.”

Now when the light is green, there is no eastbound traffic for drivers to weave through to move left; and during the flashing yellow, drivers who want to move left must wait for a safe opening in the traffic flow. Drivers who want to access the SR-92 commuter lanes from the I-15 northbound off-ramp still get impatient at times, but Lough said the flashing yellow right turn arrow has improved the traffic flow. “This provides a safer condition and has reduced the amount of backing on the ramp.”

Lough developed the idea of using a flashing yellow right turn arrow to address the traffic problems at this interchange ramp. Although UDOT had never installed anything like it, Lough suggested that it would be the best solution and worked with Traffic Operations Center staff to implement it. So far, he is pleased with the results.

“I am always looking for better ways to do things,” he said. “It is rewarding to see how changes like this make people’s commute a little better.”

Lough said the signal is almost always green or flashing yellow, but it briefly turns solid yellow and red as part of the signal’s cycle. The pedestrian button also triggers the red arrow.

“There is quite a bit of pedestrian traffic between the employment centers and retail outlets on either side of I-15 in this area,” Lough said. “Drivers really need to be on the lookout for pedestrians and bicyclists moving through this interchange.”
