Tesco won their appeal in July 1998 to build a large supermarket over the railway line in the centre of Gerrards Cross. On June 30th 2005, their tunnel collapsed narrowly missing two packed commuter trains and causing serious disruption to the rail network. Tesco have left what looks like a colossal abandoned quarry in the middle of our High Street since the collapse.
Tesco left 80 thousand tonnes of Incinerator Bottom Ash Aggregate lying around uncovered adjacent to residential homes and the shopping centre for nearly four years. A BBC ‘Inside Out ‘ programme identified possible health risks associated with the IBAA in Gerrards Cross. In response Tesco commissioned an ‘independent’ investigation and issued a report stating the material posed no significant health risks. However, campaigners were skeptical of this report proving that the material in Gerrards Cross is entirely safe.
On the 10th October, 2008, the Buckinghamshire Journal reported that Tesco is preparing to rebuild the tunnel. However they were not given final approval by Network Rail until February 2009. The store opened on 29th November 2010. Please see an article in the Buckinghamshire News, 30th September 2010.
