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.
