Highway 191 in Gallatin Canyon, Montana

The Montana Department of Transportation has issued a new advisory for Highway 191 in Gallatin Canyon. Beginning sometime the week of August 11, traffic will be detoured at Swan Creek with 35 mile-per-hour speed limits strictly enforced due to reduced visibility. MDT advises that motorists use extreme caution in this area. The detour will be in place until May, 2009. Rock excavation at Swan Creek is complete.

Additional construction continues both day and night. Please watch for:

• Reduced speeds
• Up to 20 minute delays
• Single lane traffic at night

Truck traffic in Gallatin Canyon is limited to local deliveries only. Through loads must use Hwy 287. 

Road condition updates are available via:

• Signs located throughout the construction area between Four Corners and West Yellowstone
• The project website at www.mdt.mt.gov/US191
• The MDT mobile radio station with road advisories on AM 1610 between mile posts 70 and 74. 

Please help to assure everyone’s safety by observing traffic signs and posted speed limits during construction. With construction underway in Gallatin Canyon, especially the rock excavation in the evening hours, it’s advisable to allow yourself some extra time.

Remember: Fines double in work zones and you cannot legally resume speeds until you observe an "End Work Zone" sign.

Thank you and drive safely wherever you may be traveling!

General Information

Road construction is perennial in Yellowstone National Park. In general, park roads have either been recently repaired or reconstructed, or are scheduled for repair or reconstruction. Approximately 80% of main park roads (about 185 mi or 295 km) are in a structurally deficient state, with poor quality road bases failing under the weight, speed, and volume of modern traffic for which they were not designed. Harsh winter weather and short construction seasons provide additional challenges.

These needs are now being addressed under a 20-year, $300 million Federal Lands Highway Program for Yellowstone National Park. In addition to the major construction addressed below, park road repair crews will be working in other areas of the park throughout this and subsequent seasons. Thank you for your patience with our road construction efforts.

Other road closures or delays are possible. For current road information, call: 307-344-7381.

Additional construction zones and schedules may be announced as construction contracts are awarded.
