Thanks for the info!
There's no doubt it is shorter taking route 28 from Concord to Alton Bay. Then, from Alton Bay, it takes approximately 10 minutes (a bit longer if there's traffic) to drive to West Alton Marina. According to Google maps, it is shorter in time to take the exit 20 route, going from Concord to the West Alton Marina.
But, I wonder which *actually* takes longer? The traffic between route 93 and the bypass (along with the numerous lights!) is a problem and can be unpredictable.
Hey, why wasn't that bypass built all the way to 93?
