THE Institution of Civil Engineers has announced that the A160 Port of Immingham Improvements Project has been shortlisted for a regional award.

A160 improvements merit nomination

The scheme to upgrade the link between the A180 and the UK's biggest port is nominated fo the Centenary Award.

Last year it was won by Leeds Station Southern Entrance.

While principally a road project, the A160 involved a major feat of engineering to slide a 4,000 tonne bridge beneath one of the busiest freight rail lines in Britain, a focal point of the long-running scheme that was conducted over Christmas 2015.

A 100-strong team worked around the clock to install the bridge at Rosper Road, the port's western entrance.

Highways England and contractor Costain delivered the £88.4 million scheme.

The ten-hour push – a first for a Highways England scheme, and preferred option to crane works due to the time frame involved and it being less susceptible to weather – saw the bridge moved at about 3m per hour.

Costain and civil engineering specialist Freyssinet launching a plan that was two years in the making.

Grease and visqueen was added to bentonite, pumped in below a guide raft that became the base slab, aiding the hydraulics to move the huge bridge, designed with abnormal loads in mind. It was a vital part of dualling the port entrance, making it two lanes in and out of the jewel in ABP's crown.

At the time, Costain's contract lead, Craig Snow, said: "This operation is the most complex part of the scheme. It is unique as a civil engineering challenge."

The awards highlight the outstanding work done by civil engineers from across the region.

Professor Tim Broyd, the Institution's president, will present the awards at York's National Railway Museum on March 3.

Mark Duquemin, ICE awards secretary for Yorkshire and Humber, said: "The standard of the nominations was high and we were really impressed by some of the great work that is happening in the region. I would like to thank all the nominees for taking the time to put forward an entry and helping to raise the profile of the profession."
