Overview

A diver-under structure was required to take two railway lines beneath the East Coast
Main Line, removing a key bottleneck on the network. A 150m long, 8m high, 11.5m
wide, 750m radius curved reinforced concrete box weighing 11,000T was constructed
offline and then jacked 165m into position during a 9-day partial closure of the main
line.

In this lecture, Matt Hadden will discuss the engineering challenges faced in the
construction of the scheme.
