The Montana Department of Transportation and Jeffery Contracting Inc. will close the Interstate 15 Spring Creek Interchange, Exit 219, from Sept. 14-16, weather and other unforeseen factors permitting.

During this closure, crews will improve drainage near the interchange.

MDT recommends using Exit 226 in Wolf Creek to access Recreation Road during this closure, which will extend from Lyon’s Creek Road to Woods Siding Road near the interchange.

“This closure will allow crews to place a new 4-foot diameter concrete pipe under Recreation Road to help improve drainage near the interchange,” Matt Widhalm, MDT engineering project manager, said in a release. “We are aiming to get this work completed as quickly as possible and will reopen Recreation Road and the interchange as soon as we are done.”

An additional closure of the Exit 219 northbound on-ramp and southbound off-ramp for paving will occur after this closure and the public will be notified once paving is scheduled.

Paving of the I-15 northbound lanes is currently ongoing.

Motorists traveling through the construction area should expect crossover traffic patterns, single-lane traffic traveling in both directions on the southbound side of I-15, and reduced speed limits.

A 12-foot width restriction remains in place, and all loads wider than 12 feet need to be staged and escorted. Motorists traveling through the project area from 4-6 a.m. may encounter brief interstate closures if wide-load escorts are needed.

Work on this project began in April 2026 when crews began removing and replacing more than a foot of degraded roadway material on the northbound lanes of I-15. Resurfacing the southbound lanes is expected to take place in 2027, according to MDT.
