In a remarkable engineering feat, a 1,600-tonne bridge has been strategically placed over an existing railway in Birmingham, demonstrating effective use of advanced construction techniques.
- The Aston Church Road Bridge, composed of steel and concrete, extends 84 metres in length and 21 metres in width.
- The installation operation, facilitated by specialist contractors, concluded five hours ahead of schedule, minimising disruption to rail commuters.
- Significant preparations were undertaken, including platform construction and utilise self-propelled modular transporters for precise positioning.
- Further developments will enhance the infrastructure over the next year, including the demolition of the old bridge and integration with the road network.
In a remarkable engineering feat, a 1,600-tonne bridge has been strategically placed over an existing railway in Birmingham, demonstrating effective use of advanced construction techniques. The operation, undertaken by High Speed 2 (HS2) engineers, progressed over a five-hour window and successfully positioned the new Aston Church Road Bridge over the Birmingham to Derby railway line at Saltley.
The Aston Church Road Bridge, composed of steel and concrete, extends 84 metres in length and 21 metres in width, offering enhanced robustness and durability. Notably, the bridge’s construction reflects community input, with features such as a wide pedestrian walkway, cycling lanes, LED lighting, and weathered steel panels with perforated patterns for improved aesthetics and visibility.
The installation operation, facilitated by specialist contractors Mammoet alongside the main works contractor Balfour Beatty Vinci JV, commenced at 10 pm on 10 August and concluded by 3 am the following day. The strategic planning enabled the railway to be handed back to Network Rail five hours earlier than planned, thereby significantly reducing disruption to rail commuters.
Significant preparations were undertaken, including the development of a 9,000 square metre platform and the construction of 62 piles to support the concrete structures. The bridge was moved using two 128-wheeled self-propelled modular transporters across a matting bed for stability, allowing for precise positioning over existing railway tracks without undue disturbance.
In the coming weeks and months, further developments surrounding the bridge will be completed, including finishing details such as the steel assembly of parapets. Over the next 14 months, the previous Aston Church Road bridge will be demolished to create additional space for the new HS2 line, which will eventually connect into the existing road network, signifying a major upgrade to the local infrastructure.
The successful installation of the Aston Church Road Bridge reflects innovative engineering and cooperative planning, setting a precedent for future infrastructure projects in the region.
