Innovative Engineering Brings Aston Church Road Bridge to Its Final Position

In a significant achievement for Birmingham's infrastructure, a new 84-metre composite bridge was successfully moved into position in just five hours as part of the HS2 project. This massive 1,600-tonne structure, which spans 21 metres in width, was relocated over the existing Birmingham to Derby railway line, marking a critical step forward in the development of the high-speed rail network. The new Aston Church Road bridge not only promises to improve connectivity but also introduces several innovative features designed to enhance the experience for pedestrians and cyclists.

Innovative Design and Sustainable Construction

The bridge is a composite structure, featuring a concrete deck cast over steel girders with glass-reinforced plastic panels used as permanent formwork. This design not only ensures durability but also contributes to a more efficient construction process. To support the bridge’s substantial weight, a 9,000m² platform was prepared, and 62 piles were constructed to support the concrete structures. In total, approximately 4,000m³ of concrete and 490 tonnes of reinforced steel were used in the construction.

One of the standout features of the new bridge is its integrated lighting system, which is particularly innovative in reducing urban light pollution. The lighting design is sympathetic to local wildlife, ensuring that the natural environment is preserved while still providing enhanced light levels for safety and visibility. This thoughtful approach makes the bridge not only functional but also more attractive to both pedestrians and cyclists, encouraging sustainable modes of transport in the area.

Looking Ahead: Enhancing Local Infrastructure

With the bridge now in its final position, the focus will shift to connecting it to the existing road network and demolishing the original Aston Church Road bridge to make way for the HS2 line. The new bridge rests on three key structures: an abutment to the west of the existing rail tracks, a pier consisting of two columns on the east, and another abutment further east. This carefully planned structure ensures the bridge's stability and longevity, reinforcing its role as a critical piece of local infrastructure.
