Scammonden Bridge
Scammonden Bridge, also known locally as the Brown Cow Bridge (after the nearby Brown Cow Inn, now closed), spans the Deanhead cutting carrying the B6114 (the former A6025) Elland to Buckstones road over the M62 motorway in Kirklees, West Yorkshire, England. The bridge and Scammonden Reservoir to the west are named after Scammonden, the village that was flooded to accommodate the reservoir whose dam carries the motorway. On opening, the bridge was the longest concrete arch bridge in the UK.
The bridge was built for the West Riding County Council to the designs of the county surveyor, Colonel S. Maynard Lovell. In March 1962 a model of the 37-mile (60 km) section of the M62 was displayed in Wakefield, the administrative centre of the West Riding County Council. The route of the motorway, from the A572 to the A640 at Huddersfield, was announced by Tom Fraser on 29 October 1964.
On opening, it was believed to be one of the largest concrete single spans in Europe.
The bridge had high winds; pedestrians found it sometimes hard to walk along it, so a new type of road sign, for high winds, was installed.
The £8m contract was given in late October 1966.
The bridge was planned as a flat arch bridge, but aerodynamic considerations led to an open spandrel design. The main span supports eight spandrel columns and there are four other columns over the motorway cutting. The spandrel columns are 18 inches (46 cm) thick.
The arch is a twin box section. Its deck is an inverted T-type pretensioned prestressed concrete beam. The bridge deck is 24 feet (7.3 m) wide. Using computers, its design was calculated to withstand 110 mph (180 km/h; 49 m/s) winds, and was tested in wind tunnels at the University of Nottingham and the National Physical Laboratory. The motorway cutting was profiled with 15-foot (4.6 m) 'steps'.
The road it carried was the A6025, but is now the B6114 between Elland and the A640 junction at Buckstones Moss. To the west of the bridge the M62 enters Calderdale from Kirklees; the boundary crosses the B6114 north of the bridge, and follows the north side of the M62 along Scammonden Water. The road crosses the M62 at around 1,017 feet (310 m) above sea level, northeast of Cow Gate Hill.
