A1 Closure Southbound, Lincolnshire. Monday 29 December 2014
The A1 in Lincolnshire was closed on Monday 29 December on the southbound carriageway between the B6326 near Long Bennington and the B1174 near Grantham, due to an accident involving a HGV which overturned. The HGV fully blocked the southbound carriageway lanes and a substantial righting and recovery operation was required which extended the duration of the closure.
Shortly before 13:27 this very serious incident was responded to by Highways Agency contractors after Lincolnshire Road Police Units notified the Highways Agency they were attending an overturned HGV on the A1 southbound carriageway. As a result of the accident, extensive delays were experienced by customers with substantial volumes of trapped traffic, which was regrettably caught behind the scene. With the incident itself near the village of Marston, a traffic queue of approximately 10 miles extended back to the A46 junction at Newark-on-Trent. Some of the trapped traffic was able to be released via local roads however due to the constraints of the location it was not possible to release some traffic, most noteworthy HGV’s. Unfortunately due to the HGV’s resting position, allowing trapped traffic past the scene was not an option.
At 15:00 vehicle recovery was reported as arriving at the scene and evaluating the situation. Recovery contractors with their specialist equipment remained working at the scene for a significant number of hours assessing and working to ensure that the vehicle was righted without further incident. This was primarily to avoid any further delay in getting the HGV and its load removed from the scene safely. During the afternoon Highways Agency contractors implemented the diversion for strategic southbound traffic which was diverted on our existing pre-planned emergency diversion route. This route utilising the A46 southbound from Newark-on-Trent to Bingham and then the A52 eastbound to re-join the A1 at Grantham. The diversion route was following the Hollow Diamond Diversion symbol sign. Additionally, the Highways Agency National Traffic Operations Centre set Variable Message Signing on all appropriate strategic approaches to inform customers already on our network of the A1 closure, so they had the option to consider alternative routes.
Throughout the afternoon the recovery operation was ongoing and prolonged. Recovery vehicles were finally clear of the scene at approximately 19:00, which then allowed our contractors to sweep and clear the road surface in the area to ensure it was restored to its pre-accident condition. Therefore allowing the safe re-opening of the carriageway for use by southbound traffic.
At 19:48 our contractors confirmed from the scene that the carriageway was fully re-opened and traffic flowing accordingly.
