Map Updates and Corrections (Addenda)

Updates to Recently Released Maps

If you are planning a bike tour, be sure to get the most recent map updates and corrections for your route by selecting the route, and the appropriate section(s), from the drop-down menu below.

Over time maps become less useful because things change. Every year Adventure Cycling's Routes and Mapping Department create map updates and corrections for every map in the Adventure Cycling Route Network, which now totals 52,047 miles. With the help of touring cyclists like you, we receive updates on routing, services, camping, and contact information. Until we can reprint the map with the new information, we verify the suggested changes and publish corrections and updates here on our website.

If you have updates or corrections for a map, please submit them through our online Map Correction Form.

NOTE: Map updates and corrections only pertain to long term changes and updates. For short term road closures, please see the Adventure Cycling's Routes Temporary Road Closures discussion in our Forums.

Section Information

(Sep 2019) RIDING CONDITIONS: The highway shoulder between Muddy Gap and Rawlins has been repaved and is no longer a dangerous stretch.

(Jun 2021) Effective April 23, 2021, the South Entrance Road, beginning at the South Entrance Station to the West Thumb Junction, will be closed to spring bicycling permanently. Yellowstone National Park has identified that spring bicycling on the South Entrance Road poses a significant risk to bicyclists due to the narrow roadway and lack of road shoulders. In addition, and most importantly, high snow banks, often on both sides of the road, make the road even more narrow, limits site distances and drivers' ability to see bicyclists, and leaves no escape route for bicyclists in case of the need to leave the roadway. The reopening of the road to bicycling in the summertime is dependent on how quickly the snow banks melt. For more info, see

(June 2022) YELLOWSTONE CLOSURE/FLOODING: Due to heavy flooding, Yellowstone National Park is temporarily closed to all traffic. To avoid the park, you must take the Teton Valley Alternate described below. Check here for updates:

(Apr 2021) NEW TETON VALLEY ALTERNATE: Due to safety concerns, some cyclists are choosing to visit Yellowstone National Park by renting a vehicle and driving through the Park to see the sights. The Park has heavy traffic with lots of RVs during the summer, and many of the roads are narrow 2-lanes with minimal to no shoulders. This 139.3 mile alternate to avoid the Park begins in West Yellowstone, MT, and heads west, south and east through Idaho into Wyoming. Here is the link: You'll ride 36 miles on US 20 through Montana and Idaho. The highway has variable shoulder widths, and continuous rumble strips in Idaho. It also has fast moving traffic. In both Idaho and Wyoming there will still be traffic, but we have routed onto several separate bike paths where possible. The Idaho state highways are mostly narrow, and have minimal to no shoulders. The alternate ends in Jackson, Wyoming, where you will connect to the Teton Spur on TA_Sec05. The 33.5 mile Spur joins the main route at the intersection of Teton Park Rd. and US 89/191/287. The alternate, including the Teton Spur, is 80.3 miles longer than the main route through Yellowstone. Here is a pdf that lists services on the alternate.

(Jun 2021) With the exception of Fishing Bridge RV Park and Slough Creek Campground, all of the campgrounds in Yellowstone National Park (even the ones off route) have a limited amount of hiker/biker sites. They are first come, first served. Reservations at any campgrounds at regular sites is highly advised. 

(Apr 2022) Two major road projects will impact Yellowstone National Park. (1)A major repaving project is scheduled to begin in the Spring of 2022 and last through the 2023 season. It is occurring on Grand Loop Rd. between Old Faithful and West Thumb (map 48). Expect delays and overnight closures. In the past, when there is road construction a pilot truck usually takes cyclists thru the construction section. If the construction section is short and the roadbed not seriously affected, they sometimes let you ride through. (2)A second project is the rebuilding of the Lewis River bridge, 11.5 miles south of West Thumb. It's also scheduled to begin in the Spring of 2022 and last through the 2023 season. Expect delays and overnight closures. For more information see
