It's action stations at viaduct
Published on: 25 Aug 2017
WORK is progressing well on the repairs to the southern viaduct of the ring road at Bromley Heath.
South Gloucestershire Council is hopeful that the project, which began on July 24, can be completed in 33 weeks.
Traffic on the A4174 over the river Frome is all being diverted on to the northern viaduct, meaning only a single lane in each direction. Over the summer holidays, delays have not been too bad but it is expected that drivers will be held up from this month, especially after the UWE Bristol term begins.
Most of the work is going on underneath the bridge, so the council is keeping everyone up to date via a Facebook page and a page on its website. Any queries can be sent via email to email@example.com
The information pages show how 150 tonnes of concrete have now been poured underneath the viaduct to create jacking plinths next to each abutment. These will be used to raise the structure temporarily so bearing replacement works can take place. Once complete, the viaduct will be lowered back down to its original height.
On top of the viaduct, an inspection gallery is being created. This will be used for access to bearings which need replacing in future.
The Frome Valley Walkway, beneath the bridge, will be closed on both sides for the river from August 24 for a minimum of three weeks so that scaffolding can be constructed safely.
