Bromley Heath Viaduct

Preliminary cross over work on the Bromley Heath Viaduct will take place from Monday 6 February for eight weeks. This will involve lane two overnight closures on both the west and eastbound carriageway of the A4174 on the Viaduct between 8pm – 6am.

We are developing a local traffic plan for the duration of the Bromley Heath Viaduct maintenance work and would like to invite you to attend one of our engagement events to learn more about the scheme, as well as your views on our proposed traffic measures during the duration of the work.

  • Wednesday 22 March 7-9pm – Frenchay Village Hall
  • Saturday 25 March 10am – 12pm – Downend Library

The Bromley Heath Viaduct was constructed in February 1966 as a single carriageway road over the River Frome and in 1988 was changed to a dual carriageway. Today, the viaduct carries approximately 55,000 vehicles and 500 cyclists a day. In its current form the viaduct is in need of maintenance work on:

  • pier strengthening
  • bearing and hinge replacement
  • drainage improvements
  • water proofing
  • parapet replacement
  • concrete repairs

The location of Bromley Heath viaduct

We now have the opportunity to bring the structure up to standard and improve the viaduct through the financial support of the Challenge Fund and Cycling Ambition Fund from the Department for Transport.

After considering a range of options, councillors decided to begin the work on the Bromley Heath Viaduct in June/July 2017 for a maximum duration of one year, but with an aim to try to secure additional funding to accelerate the work programme and reduce the timescale.

Both the essential maintenance of the viaduct structure and the improvements to widen the shared footpath for cyclists and pedestrians will be combined, which means that the total maximum time required on site would be one year rather than two.

We have already undertaken some preparatory work. The work includes assessing wildlife habitats and clearing vegetation where the anticipated work will take place. In addition, ecological surveys have been completed before the vegetation clearance and mitigation planting programmes will also be rolled out post completion.

The extent of the work will require the southern viaduct to be closed to all traffic for the duration of the project.

This is because the removal of the worn out parts of the structure will mean that it is too weak to safely carry any traffic until the maintenance is complete. Therefore, a crossover link will be created for the duration of the work and the current two lanes in both directions over  the viaducts will reduce to one lane in each direction. Please see the below map that illustrates how people and vehicles will be able to travel over the viaduct.

 

Bromley Heath viaduct traffic management

This is one of the busiest sections of the A4174 and will cause significant delays. We understand that this scheme may cause disruption and disturbance to residents, communities and businesses and would like to apologise in advance and kindly ask for your patience whilst this work is taking place. To help facilitate traffic movements, we have carried out traffic modelling and identified alternative travel routes across key areas, that the work will significantly impact. Please see the below schematic plan which illustrates possible alternative routes. These alternative routes will be discussed at our engagement meetings, details of these events are at the top of the page. Maps showing our traffic management proposals are available in the Downloads section of this page. Please note these proposals are indicative only and are subject to change following resident engagement.

Early stages

With a start date of June and July 2017 confirmed at the Environment Community Services meetings on Wednesday 18 January, the team are continuing to prepare the work programme and are considering the scheduling of current and future transport schemes including MetroBus, utility work and day to day scheduled roadworks to ensure the proposed programme minimises disruption to road users and communities.

Preliminary cross over work on the viaduct

We will be carrying out preliminary cross over work on the Bromley Heath Viaduct from Monday 6 February for a period of eight weeks. The preliminary cross over work will take place at the Bromley Heath Viaduct and will involve overnight closures of lane two on both the west and eastbound carriageway of the A4174 of the Viaduct between 8pm – 6am.

During the overnight work, traffic will still be able to access the A4174 on lane one on both the west and east bound carriageway. The west bound and east bound carriageways will remain fully open at weekends and all other times.

This work is part of the Challenge Fund project and cycle ambitions, in order to carry out this work as efficiently as possible and to minimise disruption to local residents and businesses, the work is being undertaken overnight. We understand this may cause some inconvenience and disruption and apologise for this.
