This summer, even if you’ve got your drive times down to a T, you’ll want to be forewarned about roadwork projects that can turn your commute into a crawl. Right now, drive times from Riverton to Dubois may be significantly increased depending on when you hop into the queue awaiting a pilot car escort through construction that’s limited 287 to one lane for miles, and throughout this summer WYDOT has dozens of projects to overhaul roadways that you should note for warm-weather excursions.

Green: Interstate highway work zones: Generally, there are no delays or detours. Travel may be narrowed to one lane each way and involve a reduced speed limit. Orange: Two-lane road projects: At times, motorists may have to drive on gravel or another temporary surface, typically for two miles or less. Delays are limited; there are no detours unless specifically noted but there may be a pilot car.  Magenta: District-wide projects: Various locations; may involve reduced speeds.
