And while the Utah Department of Transportation recently announced several of the heavy-duty projects that drivers will see throughout the coming summer and — in several cases — beyond, UDOT announced in a press release last week that it will also be hard at work on continuing to apply contrast striping on several highways in Northern Utah.

“This work is part of the Enhanced Freeway Striping project, the largest restriping project in state history, which is replacing lane markings on portions of Wasatch Front freeways with new, wider lines designed for high visibility and reflectivity,” the release said. “This contrast striping, also known as ‘tiger tail’ striping, includes a white line followed by a black line for the lines in between lanes. In addition to being easier to see, the contrast is helpful for autonomous vehicle sensors and cameras.”

The release notes that 6 million feet of the tiger-tail striping was applied to Utah roads in 2024. It also announced sections of the following roadways in Tooele, Davis, Salt Lake, Wasatch, Summit and Utah counties are expected to receive contrast striping in 2025:

• State Route 201.
• Interstate 215.
• Mountain View Corridor.
• Bangerter Highway.
• I-15 in Davis County.
• U.S. 40 in Park City and Heber City.
• I-80 in Tooele.
• I-80 from Park City to Coalville.
• S.R. 92 from Lehi to Highland.
• U.S. 189 in Provo Canyon.

UDOT Public Relations Director John Gleason told the Standard-Examiner in an email Monday that the contrast striping has been well-received among motorists.

“What we’re hearing is the new striping is really making a difference,” he said. “People feel safer on our roads. … We want everyone to feel safe while driving. We’ve been testing different kinds of striping and reflective materials for years, and found that contrast striping is the most resilient and visible for different kinds of weather.”

He said that large swathes of I-15 along the Wasatch Front have already received the new lane striping, but noted there are areas that are, and will remain, exceptions.

“Most of I-15 between Payson and Lehi is now set up with new wet-reflective tape for lane striping,” he said. “I-15 between the Point of the Mountain and 600 South has contrast striping, but there are some areas that are under warranty from previous projects the Better Lines (Enhanced Freeway Striping) project will not replace.”

“Crews will be working on I-15 in Davis County from Shepard Lane to Gentile Street (NB & SB) this year,” he added, using abbreviations for “northbound” and “southbound.” “Striping is also planned for NB & SB I-215 between North Temple and I-15. Due to an upcoming project to rebuild I-15 between 600 North and Farmington, no new striping is planned.”

Gleason said that work will largely be carried out at night.

“We work at night when there is less traffic to minimize inconvenience to drivers,” he said. “So if you’re driving at night in areas where we’re working, expect lane closures and occasional ramp closures. Just plan ahead and give yourself some extra time.”

He said he didn’t have exact dates for when the work would be carried out other than it will be scheduled throughout the summer.
