Heathrow airport directions are simple and easy to follow as the airport is excellently signposted from all routes. Local traffic can approach Heathrow from the A30 or the A3113. Please note that you must leave as much extra time as possible, particularly during the morning and evening. Traffic is heavy on the M25 and the M4 around rush hour and when there are road works in progress.

The most effective way to get to Heathrow Airport is to go via the M4 motorway. The M4 is most easily accessed from junction 15 of the M25.

If you are travelling by car terminals one and three are located just off junction four of the M4 or locally via the A4.

If you are travelling to terminal four, leave the M4 at junction three or the M25 at junction 14.

• From the North: Join the M25 using the M40 from Birmingham and Midlands, or the M1 or A1 from the North East. On the M25 head westbound for Heathrow and Gatwick until you reach junction 15.


• From the West: Join the M4 (from Bristol, Swindon, Reading) and stay on until Heathrow. If you're coming from the southwest join the M3 heading for London and then the M25 north signposted for Heathrow. Leave at junction 15 and join the M4 heading for London and Heathrow.
