At least your changes are making it to the maps(even if the road work isn't completed yet)
I've got roads around me that were changed almost 10 years ago and the maps are still not updated.....

I had a similar, but more the opposite experience. I had a route where the state was rebuilding a section of a roadway. The XT was wanting to re-route me 100 mile out of the way, and kept prompting me to recalc, and turn around. It was confusing as I was continuously meeting traffic, so I figured th...
