At the very lower end of the Susquehanna River there are 4 major
bridges . Seen here are three of them . Closest is the CSX RR Bridge,
next is the US RT 40 Bridge and the lowest one is the Amtrak NEC
Bridge at Perryville, MD . The missing bridge is Interstate 95 which
does not fit in when you try to get them all , at least from the
ground .
