The abutment towers are similar to the river towers.

On the abutment towers the chains are connected by horizontal links, carried on rockers, to anchor ties.

Each chain over a shore span consists of two segments, the longer attached to the tie at the top of the river tower, the shorter to the link at the top of the abutment tower, and the two jointed together at the lowest point.

When arches form the superstructure, the abutment must be so designed as to transmit the resultant thrust to the foundation in a safe direction, and so distributed that no part may be unduly compressed.

For spans over 75 ft., expansion due to change of temperature is provided for by carrying one end of each chain girder on rollers placed between the bearing-plate on the girder and the bed-plate on the pier or abutment.

A more common type is a bridge with two leaves or bascules, one hinged at each abutment.

If it revolves about a vertical axis d its centre of gravity must always lie in that axis; if it rolls the centre of gravity must always lie over the e abutment.

If the bridge is erected when the river is nearly dry a travelling stage may be constructed to carry the projecting end of the girder while it is hauled across, the other end resting on one abutment.

Bending moment increases uniformly from either abutment to the load, at which the bending moment is M =Rem = R 1 (l - m).

At any point x from the abutment, the bending moment is M = Zwx(l - x), an equation to a parabola.

The reaction at B is 2wx 2 /l and the bending moment at any section C, at m from the left abutment, is 2wx 2 /(l - m)/l, which increases as x increases till the span is covered.

A crown or removable denture is secured to this abutment as the final restoration.

The methods of erection may be classed as - (I) erection on staging or falsework; (2) floating to the site and raising; (3) rolling out from one abutment; (4) building out member by member, the completed part forming the stage from which additions are handled.
