Kingsferry Bridge Closure for 'Urgent' Network Rail Repairs to Begin

The Kingsferry Bridge, an essential structure connecting the Isle of Sheppey with the mainland, is set for closure to facilitate urgent repairs by Network Rail. Built in 1960 by British Rail, this 64-year-old bridge plays a crucial role in the region's infrastructure, supporting both road and rail traffic. The upcoming works aim to replace 40 steel ropes that lift the bridge, last replaced nearly 30 years ago.

Recent tests indicated that these ropes, installed in 1995, have significantly degraded, necessitating immediate replacement. The first phase of this extensive repair project will involve four sets of closures and rail disruptions, with Network Rail overseeing the maintenance operations.

The Replacement of Steel Ropes

The replacement of the 40 steel ropes on the Kingsferry Bridge is a significant civil engineering feat. These ropes are essential for the lifting mechanism of the bridge, allowing it to accommodate maritime traffic passing underneath. Over the decades, these ropes have been subjected to constant stress and environmental wear, leading to their current degraded state.

Engineers will undertake a detailed and systematic process to replace these ropes. This involves:

• Assessment and Preparation: Engineers first conduct a thorough inspection of the existing ropes and lifting mechanism to understand the extent of wear and tear.
• Precision Removal: The old ropes will be carefully removed. This process requires meticulous handling to avoid damaging the bridge’s lifting system.
• Installation of New Ropes: New steel ropes, designed to meet modern standards and withstand significant stress, will be installed. This step involves threading the ropes through the existing pulleys and securing them to the bridge’s lifting apparatus.
• Testing and Calibration: Once installed, the new ropes will undergo rigorous testing to ensure they operate correctly under load. Engineers will calibrate the system to ensure smooth and reliable operation.

Impact and Mitigation Measures

During these periods, a regular rail replacement bus service will operate between Sheerness, Queenborough, Kemsley, and Sittingbourne stations. However, Swale station will not be served due to the extensive diversion routes required.

Traffic management plans have been implemented to mitigate the impact on road users. A single lane of the bridge will remain open, controlled by traffic lights, until Wednesday, June 12, and then from Monday, June 24 through Friday, August 2. Despite these measures, the ongoing roadworks at Grovehurst Junction present additional challenges.

These comprehensive repair efforts underscore the importance of maintaining critical infrastructure and the complexities involved in balancing necessary upgrades with minimal disruption to public services.
