Inter-terminal transport

Terminals 1, 2 and 3 are within walking distance of each other. Transport to Terminal 4 is by Heathrow Connect trains or bus and to Terminal 5 is by Heathrow Express trains or bus. On Heathrow Express, Heathrow Connect and local buses (but not on the London Underground) the sections between Heathrow Central, Terminal 4 and Terminal 5 are free of charge.

ULTra Personal Rapid Transport is currently being constructed as a trial shuttling passengers to and from Terminal 5. The initial trial will have 18 pods running. ULTra are small transportation pods that can fit four adults, two children, and their luggage and will be able to carry passengers directly to the terminal. The pods are battery powered and will be initially used on a four kilometre track. If the trial is successful there are plans for a roll out airport wide.

Taxi

Taxis are available at all five terminals. The fare to anywhere in London, or within 20 miles of the airport, is set by meter. The fare to central London is between £40 and £70. BAA Heathrow: Taxis

Car

Heathrow is accessible via the nearby M4 motorway and A4 road (Terminals 1–3), the M25 motorway (Terminals 4 and 5), and the A30 road (Terminal 4). There are drop off and pick up areas at all terminals and short and long stay multi-storey car parks. Additionally, there are car parks (not run by BAA) just outside the airport, these are connected to the terminals by shuttle buses. Heathrow airport is also served by taxi services.

Four parallel tunnels under one of the runways connect the M4 motorway and the A4 road to Terminals 1–3. The two larger tunnels are each two lanes wide and are used for motorised traffic. The two smaller tunnels were originally reserved for pedestrians and bicycles; to increase traffic capacity the cycle lanes have been modified to each take a single lane of cars, although bicycles still have priority over cars. Pedestrian access to the smaller tunnels has been discontinued, with the free bus services being the alternative.

Bicycle

There are (mainly off-road) bicycle routes to some of the terminals.Transport for London free maps 'London Cycling Guide 6' covers Terminals 1, 2 & 3 while 'London Cycling Guide 9' covers Terminal 4 (as of the June 2007 revision). Free bicycle parking places are available in car parks 1 and 1A, as well as to the North and South of Terminal 5's Interchange Plaza. Cycling and Motorcycling map
