The existing Dogpool Lane Bridge was originally built around 1923 on a traditional 3 arch detail in stone and blockwork, over the years there had been minor settlement over the main arch requiring supplementary temporary support mid-span.
The stone pilaster parapet was also under-strength, and a new bridge was required.
The works involved full removal of the existing bridge (under a road closure) a temporary footbridge and service support structure installed parallel to the line of the new bridge.
Complete demolition of the existing structure new driven pile support to abutments, cast in situ abutments, pre cast edge beams with integral parapet detail and pre-tensioned & intermediate support beams (simply supported). Services reinstated in service trough and bridge reinstated to original line & level.
The new construction involves a simple span which takes out the intrusion of arch spans which impede river flow, which had caused numerous floods over the previous 10 years.
The Contract was awarded a National Considerate Contractor Award for its attention to detail and close liaison with the local community to minimise impact on daily life and the environment.
All works were completed within budget and 2 days before programmed completion date.
