Douglas Lake, or the river between portions of it, provides I-40 from Knoxville to Asheville a reason for a bridge. And the bridge was a reason for a construction project. And the construction was the reason for a delay of an hour in my journey earlier this week. The delay was the reason the sun was setting at this point, rather than when I drove in my driveway. And at least that was the end of the 2 delays where traffic was stop and go. I was very grateful to not have any accident scenes to deal with on my whole trip. Most of the drivers were very polite.
