million (estimated)
Around 112,000 vehicles use this particular section of the M1 each day,
and lane closures during work to increase capacity at Junction 15A would
have caused serious traffic delays, with no practical alternative route.
While conventional construction methods might have been cheaper, an innovative
tunnelling technique was used to install a major underpass under the 'live'
motorway that allowed traffic flow to remain unrestricted during the construction
work and drivers to be blissfully unaware of the activities beneath the
road surface, while the adjacent local road network was not forced to accommodate
additional traffic.
The judges said:
"An excellent demonstration of how to create infrastructure
whilst avoiding the disruption of millions of journeys."
