PLATE 1
Detailed diagram of construction of joint U7 of the north truss of the Ohio side span showing the joint pin, the two sets of eyebars, gusset plates attaching members of the north truss to the eyebars joint, retaining plate and the retaining pin which was inserted through a concentric hole in the joint pin and which was installed with two nuts on either end of the retaining pin. The makeup of the retaining pin, retainer plates and the use of double nuts on each end of the retaining pin were common to all eyebars joints except at the tops of the two towers and at the connections of the eyebars chain with the chain bent posts.
