In Chorley, Lancashire, Jamestown supplied plate girders which enabled the restoration of a famous piece of railway history.

The Chorley Flying Arches

Built in 1841, the sixteen flying arches braced retaining walls on either side of the rail line between Manchester and Preston. They are believed to be the last surviving examples of their kind in the United Kingdom. However, electrification of the line meant that overhead clearance had to be increased. Plans were therefore made for the track to be lowered, and at the same time it was decided that the brick and stone arches would be reinforced by underlying curved steel beams, which would need to be exactly matched to the varying width and curvature of the masonry.

Responding to Political Uncertainty

Recent political events such as the Brexit vote and the British election result have led to uncertainty in the construction industry; this is true particularly with regard to projects in the City of London and other major business centres. Jamestown Manufacturing Ltd. recognises these challenges and is ready to respond.

When sections of the Cuningar Loop pedestrian bridge were lifted into place over a meander in the river Clyde in east Glasgow, the bridge was being put together for the second time. To ensure a perfect fit, a trial erection of the hundred metre bridge had already taken place at the Jamestown Steel site.

Collaboration on a Difficult Site

Specialist surveyors were brought in to produce a three-dimensional scan of the bridge once the trial erection was completed; this was so that the scan could be checked against the dimensions of the pier and bearings already built by Robertson Civil Engineering, the contractors who were also responsible for the bridge abutments and access embankments. Progress at the site was further complicated by old mine workings and a trunk sewer, as well as electrical and water supplies running through the abutments.
