A significant investment worth £6 million is underway to enhance a critical route in Somerset. National Highways is set to improve the A46 between the London Road roundabout and the Cold Ashton roundabout, delivering safer and more reliable journeys for the thousands of vehicles that use this stretch daily.
The upgrade includes a new road surface, improved drainage systems designed to prevent flooding, and enhanced signage, including upgraded chevron signs at the notoriously tricky Hartley Bends to boost road safety.
Sean Walsh, Route Manager for National Highways, emphasized the importance of the works: “More than 20,000 drivers rely on this route every day for commuting, deliveries, and goods transport. Maintaining and upgrading this vital corridor is essential for safe and efficient travel.”

The project will unfold in phases. The first phase begins on January 18 with ground investigation surveys and the installation of monitoring equipment at Charmy Downs, laying the groundwork for future improvements. Subsequent phases will address drainage at Four Winds Farm and resurface the road at Hartley Bends later in the year.
To ensure the safety of workers and motorists, night-time closures of the A46 between the Cold Ashton roundabout and London Road roundabout will be enforced from January 18 to March 20, Monday to Friday between 8 pm and 6 am. A signed diversion route will be in place for northbound and southbound traffic. Access to properties within the closure zone will be maintained, with National Highways staff available to escort residents through the worksite.
Additionally, lane closures will occur at Charmy Down, involving contraflow arrangements on the three-lane section. Motorists are advised to plan their journeys accordingly and allow extra travel time, as closures may be subject to change due to weather or other factors.
For the latest updates on closures and traffic information, drivers should consult the National Highways daily closures page or the Traffic England website.
