A section of the M25 motorway, specifically between junctions 9 and 10 in Surrey, will remain closed to facilitate the installation of concrete beams for a new bridge. This closure is part of a broader £317 million project aimed at improving junction 10 and involves scheduled disruptions during five planned weekend closures.

During the closure, authorities have established a 19-mile diversion route that directs traffic onto A roads, some of which traverse London’s Ultra Low Emission Zone (ULEZ). Drivers whose vehicles do not comply with the ULEZ emission standards risk incurring a £12.50 daily charge if they deviate from the sanctioned diversion path. National Highways has stressed the importance of adhering to the official diversion to prevent congestion and ensure smooth traffic flow, highlighting that navigation around the signed routes could lead to increased travel times and potential fines.

Despite these directives, there has been a noted increase in motorists not following the official route, resulting in heavy traffic and disruption, particularly evident over the recent weekend. This has subsequently led to lorries and other heavy vehicles navigating through less suitable suburban streets, causing additional disturbances.

Local businesses and residents along the diversion route have reported quieter streets and a drop in footfall due to the redirected traffic. National Highways and transport authorities have advised drivers to consider alternative transportation methods and to travel only if necessary. They also recommended that motorists ensure they are prepared for longer journey times, including carrying extra supplies if travelling via the M25 during the closures.

The project is making good progress, with several beams already installed. However, the authorities continue to urge drivers to respect the designated detours and plan their trips carefully to minimize disruptions and avoid unnecessary penalties as the construction work continues.
