A new landmark for London
The new viaduct spans over 500 metres, from the end of platforms 8 and 9 at London Bridge station, through Borough Market and on to Metropolitan Junction, where the railway crosses Southwark Street. The most visible part of the viaduct, the part which spans Borough High Street, was constructed ‘in situ’, on top of the new viaduct.
The 1200 tonne, 72m bridge structure was slid into place over a long weekend in Spring 2011 – the weekend of the Duke and Duchess of Cambridge’s royal wedding – at an average speed of 7mm per hour. Constructing the viaduct in this way minimised disruption and road closures during the installation and helped to keep road and rail traffic moving during the work. The white, tubular bow truss now forms a striking new gateway to the City of London.
Working with Borough Market
Despite the majority of the construction taking place within Borough Market itself, the market traded as usual throughout the work. Some pitches were moved to a purpose-built trading space within the existing market footprint, and were moved back to the main market hall when work was completed.
Minimising the effects of construction on local residents and businesses was a key goal for the project. Other measures taken by the project to minimise our impact include building an acoustic screen to protect Southwark Cathedral from noise pollution, ensuring the construction was completed in time for the Olympics to allow Borough Market to fully benefit from the influx of visitors and ensuring no noisy work took place during the market’s busiest hours.
Keeping the market operational throughout the work introduced additional construction challenges, but was essential to help maintain the viability of the market. A temporary market roof was constructed in Jubilee Market early on to provide a space for traders displaced by the work.
