Engineers removed the old, worn-out structure and craned in the main sections of its replacement over Sunday, 5 January, while the railway was closed.

When the project is complete, in spring this year, the new bridge will be better able to handle the weight and volume of traffic crossing it.

While work continues, a temporary bridge is in place to keep the community connected to the road network.

Magda Rutkowska, scheme project manager for Network Rail, said: “It’s fantastic to complete this critical stage of work on time at Craigo Road, a huge well done to my team who carried out the work despite freezing conditions.

“Our focus now turns to diverting utilities onto the new structure, before laying the road surface ahead of the bridge reopening in April.

“We know there’s never a good time to close the railway, and we’re grateful to passengers and the community for their patience whilst this vital project takes place.”

Work at Craigo Road is due to be completed in April and is part of a wide-ranging bridge modernisation programme aimed at increasing reliability and improving performance on Scotland’s Railway.
