KGAL completes turnkey design for Stroud District Council.

LodgemoreKGAL has undertaken the complete turnkey design of a new lifting bridge at Lodgemore Lane, a symbolic feature of Stroudwater Navigation. The last remaining Strouid original historic canal swing bridge, manufactured in 1927, was removed in 2015, making way for the state-of-the-art replacement.

A pioneering feature of the new bascule bridge is that it has only one counterweight arm instead of the more traditional two. Operated by the canal users, it is lifted through one side of the deck only via a double acting hydraulic cylinder, powered by a manual hydraulic pump, and lowered by its self-weight.

KGAL’s responsibilities included producing a full structural design of the bridge deck, the mechanical design and purchase specification for the bearings, along with the preliminary designs and the purchase specification for the hydraulic equipment. KGAL coordinated site activities, liaised with suppliers and the Principal Contractor, check the designs, witness the commissioning test and produce the O&M manual.

The new bridge allows boats to pass through, making the canal navigable for three miles between Stonehouse and Wallbridge.
