Dockland Light Railway
Canary Wharf has progressed a long way since the first tenants moved there in August 1991. 90,000 people now work there; arriving via car, Dockland Light Railway, on the Jubilee Line, or even by boat; which although an unusual way to commute is perhaps not so surprising as Canary Wharf is situated on the Isle of Dogs and surrounded by water on three sides. Commuters and sightseers travelling by boat arrive at Canary Wharf via Thames Clippers which run a ferry service approximately every 10 minutes during peak hours. These provide a valuable means of transport but also result in a heavy footfall on the floating pontoon - the link between the clippers and dry land. The pontoon clearly needs to be both waterproof and able to withstand heavy traffic and by 2010 several years of wet conditions and millions of passers by had meant that the pontoon was suffering water damage and the tarmacadam screed was breaking away causing possible trip hazards.
