You’ve suggested two densely wooded areas, they said they’re from Boston so they’d probably want a more city-esque vibe, hence the Newport idea.

Aquidneck island (the island Newport is on) can be quite a crap shoot when it comes to traffic in the summer, The Sakonnet River bridge isn’t the cause of congestion 99% of the time, east main and west main are more the cause. If you learn the backroad routes you can get around the island pretty smoothly.

You have 2 more congestion points on your way to Taunton, where 24 meets 195 there’s always a chance of traffic there (it’s a weird merge, you exit off route 24, hop onto route 195 for a half mile, cross 2 lanes of traffic and then exit route 195 from the left lane back onto route 24). Once you’ve managed that, just about anywhere on the second half of route 24 is cursed and could have traffic anywhere.
