From the north, take the M25 to junction 6. Take A22 south and Arlington Stadium is signposted on right from A22 shortly after Hailsham.
From west and east, take A27 to Polegate, then A22 and head north. Arlington is signposted on the left.
Alternative faster route from the western side of the M25 is to take the M23 south and then head east on the A27.
