Instead turn right into Carpenters Road, under a railway bridge and then left into Warton Road. Follow it until the lights where you rejoin the A11 and turn right into our carpark. Join the A14 either outside Ipswich off the A12 or from the M1 where it meets the M6. Once you arrive in Felixstowe follow the signs for the docks rather than for the town. Follow signs for Dock Gate 2 which is the first of the dock-gate exits.
Parking is readily available.
Thankfully the road to and from Felixstowe is pretty good. Join the A14 either outside Ipswich off the A12 or from the M1 where it meets the M6. Once you arrive in Felixstowe follow the signs for the docks rather than for the town. Follow signs for Dock Gate 1 which is the second of the dock-gate exits. At the Dock Gate 1 roundabout take the entrance to Dock Gate 1 and just before a checkpoint take the second left into Sub-Station Road.
