Southbound I-15 Lane Configuration Changes

Drivers should plan ahead for a new traffic pattern on southbound I-15 from 5600 South in Roy to just before 650 North in Clearfield as early as Thursday, Oct. 21. The removal of the lane split was planned for earlier in the week, but was delayed due to weather. 


In preparation for the new traffic pattern, drivers can expect lane reductions on southbound I-15 through this area from 7 p.m. on Wednesday, Oct. 20, to 6 a.m. on Thursday, Oct. 21. 

These lane reductions will allow crews to remove the southbound lane split and restripe lanes. Drivers should plan ahead and expect up to 30-minute delays.

Drivers should also plan ahead for ramp closures between 10 p.m. on Wednesday, Oct. 20, to 5 a.m. on Thursday, Oct. 21, to prepare for the new traffic pattern. Crews will move one from one ramp location to another, so only a single ramp will be closed at a time. The ramps include: 

Southbound I-15 on-ramp at Riverdale Road in Riverdale

  • Drivers can detour to 5600 S. to enter southbound I-15


Southbound I-15 on-ramp at 5600 S. in Roy

  • Drivers can detour to 650 N. in Clearfield to enter southbound I-15


Southbound I-15 off-ramp at 5600 S. in Roy

  • Drivers can detour to Riverdale Road to exit southbound I-15

The lane-split traffic pattern has been in place to accommodate work in the median of I-15 for bridge work and widening. When it is removed, the three southbound lanes will be in their final location. The southbound Express Lane in this area will be opened following the completion of structural work on the Union Pacific Railroad (UPRR) bridge, which will take place in the coming months.

700 South Traffic Shift 

Lanes on northbound I-15 from 700 South in Clearfield to Riverdale Road have shifted. The through auxiliary lane from 700 South to 650 North has been eliminated. Drivers entering northbound I-15 from 700 South must merge into the left lanes to accommodate this new traffic pattern. This configuration allows crews to demo and reconstruct the 200 South bridge. Drivers are encouraged to use the on-ramps at Antelope Drive or 650 North to minimize delays when entering northbound I-15.
