A1 closure, between the A607 and the A606 in both directions, Lincolnshire. Sunday 10th July 2016
The A1 in Lincolnshire was closed in both directions between the A607 near Grantham and the A606 near Stamford on Sunday 10th July due to a collision between a Heavy Goods Vehicle (tanker) and a car which was towing a caravan near Stoke Rochford. All emergency services subsequently attended the incident, and the road remained closed for over 7 hours.
Shortly after 11:19 operators at our East Midlands Regional Control Centre were informed by Lincolnshire Police of an incident which involved a tanker carrying sodium hypochlorite and a car which was towing a trailer at the time. This had triggered the despatch of emergency services including Lincolnshire Fire and Rescue Service to deal with the situation. The tanker and the car were reported to have overturned as a consequence of the collision. Our National Incident Liaison Officers based at the National Traffic Operations Centre at Birmingham were made aware of the incident and started to report and brief internal teams and stakeholders. For our customers Breaking News was updated on our website and tweets immediately issued on our regional twitter feeds. Real time traffic monitoring data was already starting to measure delays of 15 mins and the delays were starting to rise.
The carriageway was initially blocked (traffic held) in both directions between the B6403 near Woolsthorpe by Colsterworth and the B1174 at Little Ponton, however after an initial assessment of the situation by Lincolnshire Police, they directed that the A1 be closed in both directions between the A607 and the A606. This closure would facilitate a robust emergency diversion route suitable for all vehicles. An added complication was that a lamp column had been knocked down and unsafe overhead cables had become an added risk.
By 12:09 that morning with the road formally closed between the A607 and the A606 the diversion was published and disseminated to the media by our National Incident Liaison Officers. With an assessment of the situation presented to them completed, emergency services formulated and began to put in place measures to mitigate further damage and deal with the situation presented to them. Thankfully, it had been ascertained that there were no casualties as a result of the collision. The tanker had crossed over the carriageway and had come to rest on its side. A local Power Utility Company was requested to scene to deal with the unsafe lamp column and overhead cables.
At 13:27 our East Midlands Regional Control Centre were notified that the Power Company, now on scene, had isolated the power. Lincolnshire Fire and Rescue Service were involved in identifying the tankers load and thus the correct way of making it safe. By 14:47 it had been ascertained that the tankers load was sodium hypochlorite (when dissolved in water it is commonly known as bleach or liquid bleach). There was also a diesel spillage to be dealt with and a specialist clean– up crew was requested to scene. A crane was also requested to scene to right the stricken tanker prior to recovery.
Work continued through the afternoon and by 17:40 the southbound carriageway had been swept, and on the northbound carriageway the crane was in situ and righting the stricken tanker.
At 18:35 we were able to reopen the southbound carriageway; however the northbound carriageway remained closed for recovery work to continue at scene. Delays had peaked at 30 minutes and the wider diversion route ensured that our customers be able to continue with their journey plans.
By 19:29 with all vehicles recovered, spillages dealt with (diesel only. The tankers load remained intact throughout), and the carriageway cleaned and wept; we were able to reopen the A1 in both directions. There were no residual delays.
