The A318 is a short urban A-road running parallel to the M25 in Surrey.
Addlestone - Byfleet
The road begins at the Addlestonemoor Roundabout at the junction with the A317 and St. Peter's Way (the spur to Junction 11 of the M25). It crosses over the railway, passes the 900-year-old Crouch Oak, then runs into Addlestone proper, where it meets the B3121 (the former A319), near the Runnymede Council offices in the centre of town.
After crossing the River Bourne at Crockford Bridge, the A318 leaves Addlestone and runs down towards New Haw, passing a couple of farms, a garden centre, a golf course and lots of houses. Traffic permitting, it's not too long until it meets the B385 Woodham Lane (to Woking) at a roundabout. It then swings round to the left and crosses the Wey Navigation, just before its junction with the Basingstoke Canal. Both are good places for canoeing, whilst their towpaths are excellent for cycling.
From there, firstly it's a straight run along a chicaned and gatsoed section towards Byfleet and New Haw station. There, it passes under a 9"9' restricted bridge carrying the main London - Woking railway line. It's single-track and signal-controlled and hence heavily congested around here for most of the day. The next section is even more uninspiring than what has gone before: half a mile or so of industrial estates and business parks. It then leaves its original course, which ran straight on down Oyster Lane, to take a dog-leg to the left to enter the former Brooklands motor-racing circuit, where it runs in between a joint Tesco/Marks and Spencer retail park and the remains of the Brooklands banking. At the entrance to Brooklands Airfield, it TOTSOs to the right at a roundabout, and after a short stretch of dual carriageway, it ends on a roundabout with the A245 in Byfleet.
