Booth Industries completed work in February on the £250,000 (US$393,000) contract to supply bespoke and commercial steel doors for the M25 Bell Common Tunnel.

The contract formed part of the £90.4M (US$142.1M) scheme by the Highways Agency to refurbish the tunnel. The project involves replacing mechanical and electrical equipment installed in the 1980s when the tunnel was constructed.

Booth were brought in by the main contractor Costain to supply specially designed steel fire doors fitted to the central dividing wall of the east and west bound bores of the tunnel, providing fire escapes.
