Hundreds of thousands of rail passengers face major disruption later this month with a nine day closure of half the platforms at London Bridge to allow work to rebuild the station.
Exclusive pictures below show work at the station which is part of the £6.5 billion Thameslink project.
Rail managers say the closure will allow new platforms to open in September, a key part of the project. More closure will take pace at Christmas.
ITV Meridian spoke to Dave Ward from Network Rail.
