Case study: Balloch Bridge

Background:-
HBPW worked with C Spencer Ltd, to provide a near identical replacement for the existing Balloch Bridge near Glasgow, which crosses the River Leven and was originally constructed in the early 1900’s.

A popular spot for sightseeing pedestrians, it had become apparent that the widths of the footpaths on the existing bridge were insufficient and that segregation of vehicles and pedestrians was inadequate.

Challenge
To provide a replacement bridge that utilised the existing sandstone abutments and river piers.

Solution
HBPW has designed and detailed the new five span continuous structure in accordance with an agreed Approval in Principle. It has integral abutments as well as two principal main girders supporting a composite steel/concrete road deck and cantilevered steel footpaths with aesthetically pleasing handrails.

Cantilevering the new footpaths outside the main girders of the bridge provided additional footpath width. This allowed for the increase of road width to acceptable modern standards and the segregation of pedestrians and vehicles.

Outcome
Full planning permission was achieved, including the blessing of Historic Scotland and the National Park Authority within which the bridge fell.
