Building work to create the 140-metre-long Bascule Bridge over the River Ely between Cardiff Bay and Penarth in Wales started in 2009. The purpose of the bridge is to allow access for pedestrians and cyclist across the harbour.
It also needed to incorporate a 20-metre-wide opening section to allow river traffic to pass beneath it.
Construction work was completed and the bridge was opened for Public access on July 14th, 2010.
With frequently required openings to allow traffic to pass safely underneath, the prime requirement is for the long term efficient and trouble-free operation of the bridges lifting cylinders.
