The following may be one for Harold or Ed........ :-)

I have always read and have been told PAT retained the "over the hill"
trackage (now Route 52) just in case an emergency closed the tunnel.
Considering the information presented in this discussion thread, did PAT
consider retaining another bridge crossing just in case the Smithfield span
had to be closed or perhaps if more serious weight restrictions had to be
imposed? Ken J.
