Pont Briwet Road and Rail Bridge replacement
Client: Gwynedd Council
Contractors Designers: Hewson
Form of Contract: ICE 5th with amendments
Dates work carried out: 2013 - 2015
HOCHTIEF completed the design and build Pont Briwet project, in Northern Wales, summer 2015. The scheme involved complex phasing for the demolition and replacement of the ageing timber rail and road viaduct. A critical element of this was to maintain public utilities throughout.
The new structures have a design life of 120 years; therefore they will require less maintenance than those which are being replaced. The carriageway over the structures has been widened to current standards and the footway widths increased providing better and safer access. The railway over the viaduct is carried on a separate deck, capable of an increased line speed and designed to current alignment standards.
