As noted by Eric, none exist where Acela goes 150 MPH.
Amtrak at present has no plans to eliminate the remaining crossings. The first, Miners Road scene of a fatal accident between Acela & a car, is such a small road that it simply doesn't pay to build a bridge for the 4 or 5 houses that are served by the road.
The 3 crossings in downtown New London could only be closed by totally rerouting the tracks some place else or elevating the tracks through town. Building a road bridge is impossible, as there is no place to ramp down prior to landing in the bay. Digging a tunnel would also be a nightmare that close to the shoreline. Either plan would also require building a new station too.
There is one crossing in Mystic that perhaps one day could be considered for closure, especially if the population were to increase dramatically.
After that, the remaining crossings again are simply too small with too little traffic to warrant the expense. The only way Amtrak might ever consider closing them, is if they can somehow raise the speeds in that area over 125 MPH, as then it would pay from their point of view to be able to go faster. I rather doubt however that Amtrak can find a way to increase speeds to the point where it would pay to close.
