West Main Street Bridge
Posted April 6, 2014, by ArtS (asuckewer [at] knite [dot] com)

I drove over this bridge over the weekend. It is really magnificent in person. For those traveling through the NY metro area, it less than an hour by car from Newark International (not that I recommend flying into Newark, but if you must...).

At first, the cream color that Hunterdon is now using on its antique metal bridges didn't appeal to me but it really works on making this one stand out.

The castings appear to be in great shape and all of the pertinent info is cast into the top chords. The only issue is an apparent dip in the deck of the western span when viewed from the north (the top chord does not seem to be affected).

Its amazing that this bridge is a tourist attraction while a bridge just one year newer (Meadville, PA) is about to come down.

Regards,
