Over two weekends last December, specialist teams used a 750-tonne crane to lift 32 beams – weighing a combined 720 tonnes – into place at Binley junction, Coventry.
The scheme is part of a congestion-busting upgrade to alleviate queues for drivers.
This means that drivers staying on the A46 will not need to slow down for the roundabout, while also improving traffic flows for local businesses nearby.
National Highways Project Manager, Bryan Bradley, said: “This new time-lapse footage shows the methodical and complex work of putting the beams into place as part of our upgrade at Binley junction.
“Given the scale of the task involved, the beams were lowered into place using specialist equipment. We’re making good progress on the upgrade and once the work is complete, it will alleviate congestion at a well-known bottleneck on the A46.”
Work at Binley junction started last year (2020) and is set to be complete by Spring this year (2022).
The scheme also includes improvements to the existing footways for pedestrians and cycle paths.
