AMSE were appointed for the construction of 2 new steel bridges at the M50 to M1 junction. The 2 bridge structures S01 and S02 consist of approximately 1000 tonnes of steel. Fabrication for the southern bridge S02 commenced in February 2009 with the first section erected on the 22nd April. Erection of the bridge consists of 3 night road closures of the M1 with 6 major lifts. On the 22nd of April Lifts 1 and 2 where erected from the east abutment to the east pier. On the 24th of April Lifts 3 and 4 where erected completing the clear span over the M1 and stopping just short of the M1 north bound off ramp. The final 2 lifts are to be undertaken on the 27th of April completing the full span of the bridge as far as the western abutment. In total over 300 tonnes of steel will have been erected in 3 nights between the hours of 11pm to 6am so as to minimize any disruption to traffic on the M1 and M50.
