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 48,629 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.


We have one or more versions of this map in our system. Match the BC number and print year on your map's cover to the links shown below for the most current Map Updates and Corrections. The print year is located in the lower right corner of the cover. To update an older map version, you must download ALL newer Map Updates and Corrections (addenda) for maps subsequent to yours.

Map Updates and Corrections (Addenda) are shown for a map's previous three versions. If your map is dated earlier than the listed versions we recommend purchasing a new map so you are current with all the service changes and other updates.
