Ramsey Harbour swing bridge links the main part of the town of Ramsey, Isle of Man, to the Mooragh Promenade, which runs along the seafront. It carries both a road and a footway over the River Sulby.
The bridge consists of two pairs of steel trussed arches, each pair spanning 64m to the central pivot point. It is supported at this central point by a circular pier of dressed masonry. The turning mechanism is electrically operated.
The roadway is 3.8m wide and the footway 0.76m. Traffic weights and speeds over the bridge have been restricted for many years.
The approach on the northern side is via a low eight-span viaduct. The road is carried on longitudianl steel beams at 915mm centres spanning between pairs of circular cast iron columns of about 430mm, all on aslight curve. The main beams carry transverse steel beams, which in turn carry smaller longitudinal beams supprting the deck. #iom #ramsey #swing_bridge
