For anyone traveling to MDI/Bar Harbor via Bangor, just thought I'd give you a heads-up that it might take a bit longer than expected. There is major road construction at 3 different points along Route 1A/Route 3 on the way to the island.
First, a 3.5 mile section to widen/straighten the road in the Green Lake area of Route 1A (near Lucerne).
Second, the High Street Widening project at the Main Street/High Street intersection. This is only 0.66 miles long.
Third, the recapping of Route 3 from the Ellsworth Wal-Mart to the Trenton Bridge. (To the best of my knowledge, this is only lasting three days).
As someone who commutes this route for work, I should note that it has only delayed me a total of 10 minutes either way so far. But, just thought I'd share for anyone traveling down 1A/3 towards the island.
