Constructing Windsor Road bridge

Windsor Road bridge

A project designed to replace a longstanding bridge in Cardiff with an improved, modern structure, is currently underway.

The Windsor Road bridge is being demolished and rebuilt in order to benefit the railway as well as accommodate the current and future requirements of modern traffic in Cardiff. The bridge, which carries five rail lines, as well as a road route, connects Adamsdown and Splott and spans the South Wales Mainline.

Benefits of the new bridge include greater access for pedestrians and cyclists, as well as better lighting. The new bridge has also been designed with longevity in mind, so will not need to be replaced for at least 125 years.

As part of the project, the bridge is being raised as part of Network Rail’s Railway Upgrade Plan to provide the extra space required for the future electrification of the railway. The electrification of the South Wales Mainline will result in quicker and more reliable journeys for passengers and will provide better connections between towns and cities in South Wales and further afield.

Work began on the project – which is being implemented by Network Rail – in January 2015 and is expected to reach completion in summer 2016.

Project manager for Network Rail Wales, Mark Bull, said:

“When the scheme is completed, passengers will benefit from a new and improved bridge that is better able to cope with the demands of modern road and rail traffic and provides improved access for pedestrians and cyclists. Passengers will also benefit from more frequent, faster, quieter services once this wider programme of work is completed as part of our Railway Upgrade Plan.”

Dating back to 1902, the Windsor Road bridge covers an area measuring 125 metres in length by 12 metres in width. The bridge is a significant structure in Cardiff and accommodates a number of utilities, including water, gas, electricity and fibre-optics.

The railway has remained open throughout the course of the project, so the site team is working hard to ensure that disruption to services is kept to a minimum. The road, meanwhile, is currently closed to traffic.

While work continues to make good progress on the project, the scheme has not been without its challenges. High winds and extreme weather conditions have resulted in a few delays and during early 2015 Network Rail engineers had to re-design the site’s foundations due to challenging site conditions.
