I think it’s 15 over, not necessarily 80+. If the work zone speed is 55, 70+ would be the point that it triggers.

I still think it’s reasonable though

I like CT, but the roads and sidewalks are awful. The roads a terribly designed (left exits, lanes ending right before a turn/exit that direction forcing everyone to merge over right before). The stoplights are also terribly coordinated if even linked at all. Sidewalks seem to be nonexistent outside of core areas
