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.

Through­out this inci­dent, High­ways Agency updated cus­tomers via our web­site www.highways.gov.uk/traffic-information/ and via our regional twit­ter feed @HATraffic_emids
