And when it opened I recall sections of metal plates on its ceiling fallng down, right?
Yes, some of the ceiling tiles in one of the off ramps tunnels coming from the airport into the central artery(I93) fell and killed some poor woman driving through in her car.
It actually was a huge improvement to the downtown Boston area. Now you can walk from Faniuel Hall all the way down to the harbor. Where there used to be this big ugly elevated three lane each way highway that separated the city.
It is also great when you drive in for a Sox game at Fenway. East on I90. Get off at the Prudential Center turn right and go into the parking garage.
Boston does not have a grid pattern street layout like NYC.
Boston has a dozen different neighborhoods with streets going in lots of different directions. It was first settled in 1620. The downtown section was basically an island surrounded by the Charles River, Mystic River and Boston Harbor. A big portion of the current city is land fill. The Back Bay section was part of the Charles River but had solid rock underneath. Which is why both the Prudential Tower(55) and John Hancock Building (60) were built there.
