M25 Lane Closures Junction 16 Clockwise, Buckinghamshire. Friday 05 December 2014

The M25 in Buck­ing­hamshire had 2 lanes closed within junc­tion 16 clock­wise due to an inci­dent involv­ing 2 vehi­cles result­ing in a large diesel spill.

Around 08:45 on the morn­ing of  Fri­day 05 Decem­ber 2014 an inci­dent occurred within junc­tion 16 (clock­wise) of the M25 involv­ing a col­li­sion between a HGV and a car. As a result of the impact between the two vehi­cles the fuel tank of the HGV suf­fered a frac­ture and sub­se­quently spilt a con­sid­er­able amount of diesel onto the road surface.

Our Traf­fic Offi­cers were first on scene ensur­ing that those involved were not injured and closed the lanes affected by the spillage. Work­ing closely with Thames Val­ley Police and our con­trac­tors we began to treat the spillage with spe­cial­ist absorbent. Due to the effects diesel has to the car­riage­way, an  assess­ment was needed to deter­mine if  any dam­age had been sustained.

Our National Traf­fic Oper­a­tions Cen­tre had set mes­sage signs across the region and fur­ther afield to warn you of the inci­dent and the delays. We set strate­gic diver­sion mes­sages advis­ing of alter­nate routes so as many of you as pos­si­ble could avoid being caught up in the delays.

After repeated man­ual treat­ment of the spill, a road sweeper was requested to scene to increase the capac­ity of the clean up effort. By 11:00 the sweeper com­pleted its first run and more spe­cial­ist absorbent was applied by our con­trac­tors. At 11:17 the process was repeated and the road swept once again. 2 lanes remained closed. We had con­tin­gency mea­sures in place with all the nec­es­sary resources, equip­ment and mate­ri­als ready to resur­face the road should it be required.

12:30 a third treat­ment of absorbent was applied after the road was once again swept. By doing this, and if suc­cess­ful, a full clo­sure of the road for re-surfacing could be avoided. At 12:52 we were able to open another lane leav­ing just 1 lane closed. The HGV involved in the inci­dent was recov­ered around this time.

Our con­trac­tors con­tin­ued to work hard through­out the after­noon to get all lanes open and the absorbent and sweep­ing process was again repeated for a fourth and final time.  This proved to be suc­cess­ful and at 14:45 all 3 lanes were once again available.

The prompt actions at scene and tire­less work of our con­trac­tors ensured that the M25 was not fully closed through­out the day. We later, overnight between 23:00 and 05:00, re-surfaced the road clos­ing 2 of the 3 lanes to achieve this when traf­fic would be at its light­est and the impact minimal.
