Winsford Station Bridge investigation
Post-Tensioned Structure Inspection (PTSI) – Winsford Station Bridge, A54, Winsford
Latest update
Following further safety assessments, the bridge will be turned back to a two-way arrangement but with a 7.5 tonnes weight restriction to protect the bridge - warning signs are currently being manufactured and we are aiming to have this in place as soon as possible.
Manned temporary traffic signals were trialled at Bostock roundabout but didn't improve the current traffic delays for vehicles leaving the industrial estate.
Background
Winsford Station Bridge is a four-span post-tensioned structure that carries the A54 over the electrified West Coast Main Line railway next to Winsford Station.
Constructed in the early 1960s, the bridge is an important link for both the local road network and the national rail network.
What is a post-tensioned bridge?
Post-tensioned bridges use high-strength steel tendons embedded within the concrete to give the structure its strength.
A specialist inspection is required to assess the condition of these tendons, as they are not visible from the outside.
What is happening now?
Recent engineering assessments have identified issues that mean traffic restrictions need to remain in place while further investigations and assessments are completed.
Engineers have confirmed the bridge is not at immediate risk, but the current restrictions are required to ensure it can continue to be used safely.
Working over the railway
The bridge crosses the West Coast Main Line, one of the busiest rail routes in the country.
Some elements of the work can only be carried out during pre-planned Saturday night railway closures, agreed in advance with Network Rail.
This means the works must be carefully phased and coordinated, with preparation works taking place during the week and the most sensitive operations carried out overnight when rail access is available.
