The direct rail link into Luton Airport has moved a step closer with a bridge to carry trains over the main A1081 road now in place.
The bridge was lifted into place using heavy duty jacks and took around 3 hours to get the components into place.
The 1,000 tonne structure was built off site near the Percival Way roundabout and rolled down into position.
This has been an exciting achievement and a hugely significant milestone in the delivery of the innovative DART scheme. The whole project has been full of engineering challenges and to move an object of this size ranks as one of the biggest."
Once operational in 2021, the £225m Luton DART (Direct Air-Rail Transit) will speed travellers from Luton Airport Parkway station to the terminal of London Luton Airport in well under four minutes.
Passengers will be able to travel between St Pancras and London Luton Airport in just 30 minutes
