Just ran across this posting on the "old" Yahoo Hi Lo Group. Don't know if it is true or not but worth checking if you are headed that way.

The Alaska Highway is currently closed in 2 places due to flooding. The following CBC news article is dated June 8, and includes updates from June 9:

I've been unable to find any info source giving an estimated date of re-opening of the Alaska highway.

If you know other RVers who are headed to Alaska, please forward this message to them.
