"Bridge Construction"


Manchester Hulme Arch:

Completed in 1997, this dramatic road bridge is suspended from a 28m high arch which runs diagonally across the deck.  The arch was fabricated in six sections and assembled on-site into two halves.  These were lifted into position onto pre-surveyed holding down bolts and joined at the apex.  The arch was re-surveyed and the required lengths of the 22 no. stay wires were calculated before being installed.

Gateshead Millennium Bridge:

This bridge was entirely fabricated in Bolton, and assembled in Wallsend, Newcastle.  This photo shows the third and final deck section being lifted into place jointly by two heavy lift cranes.  Once complete, the whole bridge was lifted onto a barge and carried 5 miles up river to be placed next to the existing Tyne Bridge.

London Wall Pedestrian Footbridges:

During the construction of a 13 storey office block in central London, two pedestrian link bridges were installed.  Each weighing over 60 tons, the single span bridges were lowered onto holding-down bolts with just a few millimetres to spare!
