this bridge has the old style rocker bearings that are not used much in pa anymore sort of acts like a rocking chair when the bridge deck expands in the heat of the day they rock over and return back to a straight or plum position when the deck cools down. these are not a ball bearing by any means only a sold piece of steel.
