2021 Construction Projects Affecting Roads

1. Tower-Roosevelt to Canyon Junction ~ ROAD CLOSED ALL YEAR ~

Improvements: This segment of road remains largely unchanged since the last improvements in the 1930s. This construction project will widen the road and provide additional/improved pullouts; create a larger, safer parking area at Tower Fall General Store; and improve the trail and overlook for Tower Fall. To fund this project, the park received a grant through the Nationally Significant Federal Lands Program and will match it with fee dollars collected in the park.

Access: The road between Tower Fall and Canyon Junction will be completely closed for the 2021 season. There will be no access to the trails for Mount Washburn. From early November through March, Tower Fall and trails in the vicinity will be open for skis and snowshoes, snow-permitting (follow all closure signage posted at Tower-Roosevelt). The anticipated completion date for this project is May 2022.


2. North Entrance

Improvements: The North Entrance is not equipped to meet the challenges of increasing visitation and traffic. This construction will add an additional lane and kiosk to improve traffic flow and reduce lines; replace the existing two buildings with one larger building/station and two kiosks; improve the flow of employee and delivery traffic from Robert Reamer Avenue; improve pedestrian safety by realigning parking along Robert Reamer Avenue; and replace the water line along Robert Reamer Avenue. Funding for this project comes from the Federal Highways Administration, Yellowstone Forever, the National Park Foundation, and fees collected in the park.

Access: Expect construction and traffic pattern changes around the North Entrance. The entrance station will be open. This project started in 2020 and will be completed in late 2021.


3. Old Faithful Overpass Bridge

Improvements: Work on the Old Faithful Overpass Bridge includes deck repairs, new approach slabs, new curbing, girder repairs, railing improvements, and the removal and replacement of deck drains.

Access: Travelers can access Old Faithful and the Upper Geyser Basin, lodges, stores, clinic, and gas station, but expect delays up to 15 minutes to accommodate one-lane travel over the bridge. The anticipated completion date for this project is late 2021.

Yellowstone National Park is a large park at 2.2+ million acres and 251 miles of roads. At this point in time (2021), the roads are the best they have been for a very long time. There has been a lot of new construction and the park service has tried to do overlays on the other areas that were in bad need of repair.

All of Yellowstone roads are two lanes. There is limited space for pulling off the roads, and limited passing zones. There are a few roads with shoulders for bike riders. There are roadside pullouts for viewing areas, or wildlife, or for parking for hikes. Slower traffic is strongly encouraged to be courteous and think of other drivers and visitors and to utilize pullouts.

There are several areas where there are steep grades and winding narrow roads. These areas are: Sylvan Pass (8,530 feet / 2,600 meters), Craig Pass / Continental Divide (8,391 feet / 2558 meters), Mammoth Hot Springs to Gardiner, Montana (6,239 feet / 1,902 meters). The road from Mammoth Hot Springs to Gardiner is narrow with some fairly sharp turns, it is best to use low gears as your brakes will heat up. Some visitors who arrived in Gardiner wanted to find a garage to look at their brakes as they were hardly working by the time they got to Gardiner. All that was needed was time to allow their brakes to cool as they had overheated from usage on the drive down.

If you look at the above park map, you will note that the park roads are roughly in a figure eight, with an Upper Loop, a Lower Loop, and a Grand Loop. The total road mileage in the park is 251 miles, the Upper Loop is 70 miles around, the Lower Loop is 96 miles around, and the Grand Loop is 142 miles around. The park top speed limit is 45 miles per hour, with many areas with lower speeds. The speed limit is strictly enforced, you will not want to get a ticket while on vacation and most animal deaths in the park involve vehicle accidents. Be careful and enjoy your time in Yellowstone.

During the main tourist season (mid Jun - mid Sep) the roads are crowded. There will be times that wildlife will be on the road, they have the right of way. There will also be what is known as buffalo jams, elk jams, bear jams and wolf jams. You cannot stop and park your vehicle in the middle of the road to take pictures or watch. You have to pull completely off the roadway so you are not blocking traffic. Utilize pullouts, parking areas, and/or road shoulders if available.

It is hoped that this information will be helpful in planning your trip and time in Yellowstone. Be careful, have fun and enjoy the beauty, magic, and wonders of Yellowstone!
