Work to undertake critical repairs to the Claverton Street railway bridge in Bath will see part of the A36 closed overnight between June and October, Network Rail has announced.

The repairs are being made to ensure the safe and reliable running of the railway through the city.
Network Rail has said it will begin work on the Claverton Street railway bridge, which sits above the A36 at Churchill Bridge roundabout, on Monday 20th June, lasting until Sunday 16th October.
To minimise disruption to road users and rail passengers, the refurbishment will take place at night.
Between the hours of 6am and 7pm daily, the road will be open as usual and train services will remain unaffected throughout.
The bridge, which sits just outside Bath Spa station, needs extensive steel and brickwork repairs.
Around 17,500 tourists, commuters and visitors travel by train to Bath Spa station every day and, once complete, the work will extend the lifespan of the bridge for at least another 25 years.
As part of the £800,000 project, Network Rail’s team of engineers will be working throughout the evenings both trackside on the top of the bridge, and from the road underneath the bridge grit-blasting and repairing metalwork, before applying a protective layer of paint.
Brickwork repairs will also be completed to the sides and support structures of the bridge.
To carry out this work safely for rail and road users, and pedestrians, the A36 at Churchill Bridge roundabout will need to be closed to all eastbound and southbound traffic from 7pm to 6am between 20th June and 16th October, seven days a week.
Between 20th August and 9th October, Network Rail’s engineers will only be working trackside each Saturday evening meaning the road closure on Saturdays will differ, lasting between midnight and 7am.
During this period of work, a diversion route, approved by Bath and North East Somerset Council, will be in place as follows:
- All northbound traffic including access to the A4 London Road, A46 and M4 motorway will travel via Green Park Road and Charles Street to Queen Square, and then via Gay Street and George Street onto the A4 The Paragon.
- All eastbound traffic including access to Bathwick, Bathampton and Warminster, will travel via the A3039 Dorchester Street and Manvers Street to North Parade before turning left onto the A36 Pulteney Road (South).
- All southbound traffic including access to the A367 Wellsway to Radstock and Midsomer Norton will travel via the A3039 Dorchester Street and Manvers Street to North Parade before turning right onto the A36 Pulteney Road (South).
- All Westbound traffic towards Keynsham and Bristol leaving the city centre will either follow the southbound diversion before travelling onwards via the A36 Lower Bristol Road, or travel out of Bath via the A4 Upper Bristol Road.
Network Rail says it has worked closely with B&NES Council and other businesses and stakeholders in the city to identify any largescale events that would be significantly impacted by the work, and has adapted its programme and agreed to stand down work on a number of dates to accommodate events, including the Michael Bublé concert (15th-16th July), Bath Boules (22nd-24th July), and the Fantastic Food Festival (29th-31st July).
Michael Contopoulos, Network Rail’s Project Director, said: “The Claverton Street railway bridge is a significant piece of rail infrastructure that carries around 17,500 rail passengers in, out and through the city of Bath each day.
“Now it needs important repairs to extend its lifespan and structural integrity.
“To carry out this work safely, we need to close the road underneath the bridge and for that we apologise for the disruption this will cause road users.
“We are aware of the impact a traffic diversion will have in such a busy city centre location and we have limited our working to overnight shifts to minimise disruption to road users as far as possible.
“Some of our work may be noisy at times and we again apologise if any nearby residents are affected by this work.
“We will be doing all we can to complete this work as quickly and quietly as safely possible, and we would like to thank residents, businesses and road users in advance for their patience and understanding.”
