Built between 1812-15, the Craigellachie Bridge spans the River Spey and was designed by engineer Thomas Telford. It is the oldest surviving cast-iron bridge in Scotland and is considered one of the finest of its type in Britain. Castellated stone abutments support four ribs that form the single arch of the bridge, above which the roadway is carried by latticed girders.

(Location cited as NJ 285 452). Craigellachie Bridge. This bridge was built in 1812-15 by engineer Thomas Telford and is one of the finest cast-iron bridges in Britain. A single 150ft (45.7m) arched span, with 4 ribs, is supported by rustic ashlar abutments, with castellated terminals and rubble wing walls. One of the terminals (on the Banff side) has 2 cast-iron plaques with the legends 'CAST AT PLAS KYNASTON RUABON DENBEIGHSHIRE' and '1814'.

J R Hume 1977.

This bridge is the oldest surviving iron bridge in Scotland. It cost 8,200 pounds sterling, which was 200 pounds sterling more than the estimate, and the money was found by the Parliamentary Commissioners and by local subscribers. It was restored in 1964 by Banff, Moray and Nairn County Councils, and by-passed in 1972.

The ironwork was cast at Plas Kynaston by William 'Merlin' Hazledine, Telford's normal ironmaster. It was erected by William Stuttle, Telford's foreman, and the stonework was by John Simpson, mason, of Shrewsbury.

The bridge is situated to take advantage the constriction formed by an outcrop of hard Moinian gneiss. Telford allowed for floods by placing the bridge on abutments 12'(3.7m) above normal water level; it withstood the flood of 1829, when the Spey here rose 15' 6" (4.7m), although the flood arches were washed away.

The four ribs are mounted 15' (4.6m) apart and they make an arc of smaller radius than the roadway, which partly accounts for the lightness of the bridge. The spandrels are formed of diamond lattice which also contributes to the delicacy of the design. The castellated rustic ashlar towers that decorate the abutments are 50' (15.2m) high and hollow with false arrow slits; they are perhaps rather heavy.

G Nelson 1990

This bridge formerly carried the A941 public road over the River Spey between the parishes of Knockando (to the N) and Aberlour (to the S), within the pre-1975 counties of Morayshire and Banffshire respectively. Both these parishes fall within the post-1975 Moray District of Grampian Region.

Information from RCAHMS (RJCM), 7 December 1995.

The location assigned to this record defines the apparent midpoint of the span. The available map evidence suggests that it extends from NJ c. 28523 45224 to NJ c. 28542 45164.
