REMINDER: Splott Road bridge in Cardiff closed from next weekend while Network Rail carries out upgrade work


Residents are reminded that Splott Road bridge will be closed from 13 August while Network Rail carries out modernisation work as part of the Railway Upgrade Plan to improve journeys for passengers.

The bridge, which connects Adamsdown to Splott, is currently too low to accommodate the overhead line equipment needed for trains running on electricity and, at 117 years old, the bridge has reached the end of its lifespan. The existing bridge is being demolished and replaced with a new and improved structure, heightened to give clearance for trains running on electricity and strengthened to withstand modern city centre traffic.

Andy Thomas, route managing director for Network Rail Wales, said: “We are reconstructing Splott Road bridge as part of our Railway Upgrade Plan to prepare the railway for the overhead wires and posts that will power trains running on electricity.

“The new Intercity Express trains, which can run on electric and diesel, will provide extra seats and faster services for thousands of passengers. It will also mean a quieter and greener environment for communities living alongside the railway. We are working closely with Arriva Trains Wales and Great Western Railway to improve services for passengers.

“We would like to thank residents for their patience and reassure them that we are only closing the bridge when it is absolutely necessary for public safety.”

The bridge is being rebuilt in two phases to help maintain traffic flow and pedestrian access. It will be closed to all vehicles for three weeks while half of the bridge - the carriageway carrying traffic from Adamsdown to Splott - is demolished. The bridge is expected to reopen on 4 September. Following the reconstruction of the Adamsdown to Splott side of the bridge, the remaining side of the bridge will close, with the second phase of the bridge’s reconstruction completed by autumn 2018.

Pedestrians will still be able to access the bridge except for limited periods of demolition work when the bridge will be fully closed with a diversionary route in place. During these times, a fully accessible minibus service will be available to transport members of the public from one side of the bridge to the other.

Work is ongoing at Adamsdown footbridge, which is closed every Saturday from 10pm until 7am on Sunday until autumn 2017. The footbridge will be completely closed over August bank holiday weekend from 26 – 28 August.

Rail passengers are advised to check before travelling as services between Newport and Cardiff will be reduced between 19 August and 3 September 2017 as work continues to modernise the South Wales Mainline.

About Network Rail

Network Rail owns, manages and develops Britain's railway - the 20,000 miles of track, 40,000 bridges and viaducts and the thousands of signals, level crossings and stations (the largest of which we also run). In partnership with train operators we help people take more than 1.65bn journeys by rail every year and move hundreds of millions of tonnes of freight, saving almost 8m lorry journeys. We employ 36,000 people across Britain and work round-the-clock, each and every day, to provide a safe, reliable railway.

About the Railway Upgrade Plan

The Railway Upgrade Plan is Network Rail's investment plan for Britain's railways. It makes up two-thirds of Network Rail's £40bn spending priorities for the five years to 2019 and represents the biggest sustained programme of rail modernisation since the Victoria era. It is designed to provide more capacity, relieve crowding and respond to the tremendous growth Britain's railways continue to experience; passenger numbers have doubled in the past 20 years and are set to double again over the next 25 years - so we need to continue to invest in building a bigger, better railway. For passengers, that means:

  • longer, faster more frequent trains;
  • better, more reliable infrastructure; and
  • better facilities for passengers, especially at stations.
