Transport for London (TfL) has completed a major refurbishment of the Fore Street tunnel, in north London.
Since April 2015, TfL and its contractors, BAM Nuttall, have been working overnight to carry out a range of improvements to the tunnel, ensuring it can remain usable for decades to come. The work included installing new waterproofing within the tunnel – with more than 30 tonnes of pre-cast concrete wall slabs and 70 tonnes of poured concrete used to help put an end to the ongoing problem of leaking water within the structure. Repairs were also made to equipment damaged by leaking water.
The existing lighting within the tunnel was upgraded to long-life LEDs, lowering energy consumption by 40% and reducing future maintenance costs.
Nick Fairholme, director of projects and programmes for surface transport at TfL, said: “Safety for all road users is a top priority for us and the water issues within the structure, which have been present since the tunnel was built in the 1990s, posed a real threat to the long-term operation of the tunnel.
“Thanks to the great work and effort put in by the engineers, we’ve now modernised this tunnel in a timely manner.”
