M1 Closure J20 - J21 Northbound, Leicestershire. Thursday 04 December 2014
The M1 was closed on Thursday between junctions 20 and 21 in Leicestershire due to an incident involving 2 cars.
Leicestershire Police directed that the M1 be closed due to an incident involving 2 cars. The incident occurred around 18:40. Highways Agency Traffic Officers and the Ambulance Service were also in attendance. Our East Midlands Regional Control Centre set signs and signals to warn motorists of the incident
19:32. With the closure in place, the Emergency Services in attendance were actively involved in treating the casualties at scene. At this stage there was approximately 2.5 miles of trapped traffic (vehicles that were caught within the closure), and congestion was almost back to J19, building rapidly. A signed diversion was instigated by the Highways Agency with motorists directed to follow the Hollow Black Square symbol via the A5 and the M69 (see map below).
A plan was put into place to release the trapped traffic by rearward relief , whereby traffic is turned around on the affected carriageway to travel in the reverse direction, in this case to junction 20 where it exited. This process was a lengthy one due to the considerable amount of vehicles within the closure, some 2.5 miles of traffic.
Leicestershire Police along with our Highways Agency Traffic Officers organised recovery vehicles for the 2 cars and a full Police investigation ensued.
We were due to have in place on this night a planned full closure of the M1 northbound for carriageway re-surfacing, however, mindful of the fact that our customers were already experiencing considerable delays and inconvenience due to this incident, we decided not to go ahead with the roadworks to avoid further disruption to journey plans. At 01:40 all the trapped traffic was released,and then it was just a case of recovering a number of broken down vehicles within the closure (which were not associated with the accident). Delays at this time were clearing. Leicestershire Police concluded their investigations and we were looking to get the road re-opened. This occurred at 03:35 with all the broken down vehicles finally recovered.
