Here is an update I received this morning.
Sean, IHC should be done with all construction and lane closures and traffic impacts by Friday May 10th, but hopefully earlier if weather permits. In the meantime, all rest areas are still open – No Name, Grizzly Creek, Shoshone, Hanging Lake, and Bair Ranch. We recently modified the traffic control at Hanging Lake to allow drivers to turn around at Hanging Lake, thus it is possible to now get back on WB I-70 here instead of having to turn around at Bair Ranch. It’s now more convenient for boaters leaving and returning to Glenwood.
