Bromley Heath Viaduct will undergo a £5.9 million maintenance programme to strengthen the 1960s structure and provide improvements for cyclists and pedestrians.
The improvement works will be carried out west bound, between the Bromley Heath roundabout and the Hambrook / Bristol Road junction.
They will begin in June/July this year 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.
Because of the extent of the work, the southern viaduct will be completely 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 it is too weak to safely carry any traffic until the maintenance is complete. During the closure, all traffic will be diverted on to the northern viaduct as other options would require a significant one to two mile diversion on to narrow roads.
Unfortunately this will cause significant delays, as this is one of the busiest sections of the A4174, and the impact will be felt on other local roads too. Ultimately if the work wasn't done, the southern viaduct would become too unsafe to use.
