Massive machines moved into North Tyneside on Friday in a bid to complete the final underpass crossing the new Northumberland railway line.
The line, which currently carries freight trains, had to be shut for a total of 100 hours as engineering teams worked round the clock to install the 400 tonne concrete structures.
A self-propelled modular transporter (SPMT) - a giant multi-wheeled trailer used for transporting massive objects from large bridge sections to spacecraft - was used in the construction, with the project set to be completed on Tuesday.
