The A209 is a short suburban road in southeast London linking the A206 and A207.
The road starts as Wickham Lane from the A206 Plumstead High Street at a mini-roundabout. Within 30 yards of the junction is a Zebra Crossing. The roads passes typical Victorian/Edwardian terraces and newer low rise flats. Parking is allowed on both sides of the road and it also forms part of two bus routes. This can cause hold ups.
Railway bridge in Welling
A secondary school is passed before a traffic-light-controlled crossroads with two unclassified routes. A large Wickes is on the right. Presently the road changes its name to Upper Wickham Lane and passes Plumstead Cemetery is on the left.
After meeting Okehampton Crescent at a roundabout the A209 continues southwards with, to begin with, an open space on both sides before becoming urban once again. Then it goes past another secondary school and under a railway bridge before going past a Lidl. Some small shops then appear and the road ends at traffic lights on the A207 Welling High Street.
This is the same as the original 1922 route of the A209 - but the road has been extended and curtailed in the intervening years.
Following a multiplex west along the A207 back under the railway line, the A209 also used to run along Welling Way. This is quite an impressive-looking road, roughly a mile long, running off the A207 Bellegrove Road just west of Welling and into Oxleas Wood. It once formed part of Rochester Way (the old A2), in the days before the motorway-style East Rochester Way was built. These days, however, the A2 runs along the new Rochester Way Relief Road, and the original Rochester Way is unclassified. For some years the A209 ended on an unclassified road but Welling Way has now been declassified as well.
