The floor rails are no longer supported by the superstructure, but by the stautions (in the stream). As you said, this bridge is under repair and hopefully someday, the floor will be tied again to the superstructure. This style of bridge construction is old. I'm betting this bridge is over 100 years old. Several bridges of this style with I-Bar tension members have failed in Ohio, thus are being phased out or refurbished. The main box members of the superstructure are made of flat plates and channel iron hot riveted together. This is the hallmark of this type of bridge, and is not seen in today's bridges. Also, if you examine the truss structure, there should be adjustable tension members with turn-buckles in the center of the tension rods. In the days when this style of construction was popular, there was a professional occupation called a "bridge tuner". After the bridge was roguhed in, it was his job to adjust the tension members so that each part of the bridge was carrying equalized loads. He 'tuned' the bridge much as one would tune a piano. By adjsuting the tension members, then striking them to make them ring, he could compare one memeber to another for tension. The frequency of ringing was a function of the amount of tension in the rods. After the bridge had seen some use and settled a bit, he would return to touch up the "tune" of the bridge.

Thanks RockinC, Photo2 and Carol... Photo2 BCSP is in East Liverpool, OH...It's only small part of Little Beaver Creek State and National, Wild and Scenic River...A beautiful park and it never disappoints me for photo opportunites... juanital

There is wildlife, but the most to see in the main part of park are fowl:hawk, crow, a couple different woodpeckers, smaller birds, etc...Last year we saw an eagle...Can occasionly 'hear' deer...I don't snap good pics of birds, got a groundhog last year that was half way decent...We occasionally walk the trails...but probably, no matter how quiet you walk, don't see much of anything else... I suppose if you get there early, early...and this is what dh says, probably can see the animal kingdom waking up! juanital

Thanks Bigack and Joan... Bigack you would have a blast there...there are trails leading off from here...I haven't done the walking trail that overlooks...yet! I think that would have to be a day with packed lunch and no pressures of having to do anything else...I easily take 300-400 pics in this part of park alone...of course alot do not come out...I get enthralled with it....
