A40 Oxfordshire
Location & Overview
John F Hunt Concrete Cutting carried out the successful demolition of the Burford Bridge, which spanned the A40 in West Oxfordshire. The bridge was a post-tensioned structure supported on two end columns with stairs on either side connecting to the main span.
Work, Challenges & Solutions
The lead handrails were flame cut and removed from the bridge, whilst cores were diamond drilled into the columns to create lifting points.
A diamond wire sawing technique was used to cut and separate the main beam and stair column connections.
The main beam was then underslung using a mobile crane, and the structure was lifted in sections onto bearers at road level and then onto transport for removal from site.
All the materials following transportation were recycled and reused.
Due to the A40 being an extremely busy route, the road could only be fully closed for one night. Therefore, the programme of works was very tight.
Achievements
Skanska commended on our works “We are very pleased with the professional manner in which John F Hunt has acted throughout the planning and implementation of this scheme. The demolition was efficiently and safely carried out to ensure disruption for motorists was minimised, and the safety of the public and works was maintained.”
