In 15.5 hours the Highways Agency and its contractors (Armac, the demolition company, and Costain-Carrillion JV, the main contractor), closed the M1 motorway in Bedfordshire, and prepared it for the demolition of the old A5120 road bridge, built in 1959 and weighing over 1400 tonnes.
Demolition began at 9:15 pm on Saturday June 30, 2012, with the hydraulic breakers making short work of the concrete and steel structure. The M1 was fully re-opened from 11:30 am the following morning.
