Significant closures will affect the A1M beginning on January 29 at 8pm and are expected to remain in place until February 5 at 6am. The restrictions are set to cover both northbound and southbound carriageways from junction 61 to junction 63 for barrier renewals, resulting in lane closures and speed restrictions. The carriageway will be closed for essential patching work, and lane closures are expected during these times. The restrictions are set to remain in place during these hours, and residents are advised to plan accordingly. Residents can check the Durham County Council website for a comprehensive list of roadworks and expected closures throughout the area.
