The new Thames cable car, spanning the river, opened to the public on 28th June 2012. The Emirates Air Line links the O2 Arena in Greenwich, south-east London, with the ExCel exhibition centre at the Royal Docks in east London. The service can carry 2,500 people an hour. A single adult fare on the pay-as-you-go Oyster card will cost £3.20 while the cash fare is £4.30. But the fares are not included in travelcards or Oyster capping. The service will operate through the week from 07:00 until 21:00. The gates will open an hour later on Saturdays while the service will run from 09:00 on Sundays. Passengers will also be able to make a non-stop round trip on the cable car, with views of the City, Canary Wharf, the Thames Barrier and the Olympic Park, at a cost of £6.40 with Oyster. But Transport for London said a one-way journey at peak time will be between four and five minutes long, but off-peak the same journey will last about 10 minutes. The Dubai-based airline Emirates is sponsoring the cable car for 10 years at a cost of £36m. The total cost of the project is about £60m, £45m of which went towards building it.
