Such logic does not exist in Massachusetts. Mark Snyder Waltham Burlington Cambridge Framingham Boston
Roads, bridges, exit signs, street signs and such all seem to be haphazardly placed in whatever manner seems the easiest (cheapest, perhaps) at the moment. EXIT ONLY lanes are rare (though they have grown a bit in the past 2 years) and efficient design seems to be all but ignored.
State roads tend to meander through towns, often making several complete and unpredictable turns, which in the absence of good signage could send an out of towner in the completely wrong direction. So watch for signage and if your route number seems to have disappeared, consider that you might have missed a turn.

So, getting around is easy if you are local and is very difficult if you are not. Expect to get lost, to get stuck, to miss your turn or to get stuck in traffic. A GPS will help get you there eventually but just don't expect anything to happen on time.
Additionally, Boston area road quality is notoriously horrendous. Towns such as Belmont, Watertown and Cambridge, have especially poor road conditions, with massive potholes, band-aide fixes and frost heaves that haven't been addressed in decades. The towns blame the problem on money, which makes sense. Lack of funding results in repairs rather than actually rebuilding roads to last. This short-sightedness of course results in never fixing the problems, never having good roads, always having some sort of construction issues going on and leaving lots of hub caps along the road side. My personal opinion is that these excuses are unacceptable for a modern society. I have seen better roads in third world countries. If you are not collecting enough money to maintain your infrastructure, then you are not doing basic parts of your job. There should be no tolerance for huge potholes that persist for a decade, especially in a state which relatively speaking is affluent and modern. Yet Bostonians are so used to it, we cannot see the forest through the trees. We persist on just tolerating poor infrastructure and complaining that we don't want to pay to fix the problem. Why would you pay to fix problems with your car and not pay to fix problems with the roads that they drive on? It makes no sense to me!
Construction in Massachusetts is notoriously poorly done (though I will acknowledge that very few places do it right). Keeping traffic moving during construction means understanding traffic patterns. Studying driving speeds and the first point of notice for a construction site, should help in the planning of road signs and flaggers. The more 'last minute' a lane merge is, the more likely a bottleneck. For this reason, advance notice to slow down and start merging, can really alleviate a crunch at the last minute to move to the correct lane. Connecticut does this particularly poorly, but Massachusetts is right behind. Investments in good signage and cones along with strategic placement would really improve the flow of traffic during construction (which often lasts for years in Mass).
