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.
