Railway bridge in the context of "Suchiate River"

An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end that provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan.

The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault. The impost or abacus of a column in classical architecture may also serve as an abutment to an arch.

Barrow rail bridge, (or the Barrow viaduct), is a pratt truss type of railway bridge that spans the river Barrow between County Kilkenny and County Wexford in the south east of Ireland. This rural landmark with a length of 2,131 ft (650 m) is the longest bridge on the river. It was second longest bridge in Ireland and the third longest rail bridge in the British Isles. Designed by Sir Benjamin Baker and built by the firm of Sir William Arrol. It is known locally as Barrow Bridge.

Part of a development to improve cross-channel passenger services. The steel truss single track bridge was built between 1902 and 1906 by English and Irish railway companies, it operated passenger services between Rosslare Harbour and Waterford until 2010. It is maintained by Iarnród Éireann, the Irish rail operator.
