Merton have an unofficial policy of tolerating pavement parking in certain roads. I have that on good authority, but it's also obvious to anyone who walks along Lower Downs Road (below) or Arterberry Road, to give two examples.
Now imagine you're a mum with a baby in a buggy and another young child walking. If the vehicle above has to reverse to get out of its parking space, they won't see a child that is close to the rear of the vehicle. Think if you're sending your little sweetheart to school at the nearby Dundonald Primary. If your child is walking on their own to school, they will face the twin hazards of vehicles manoeuvring on and off the pavement, and because children are forced to walk in a narrow corridor close to the garden walls with the parked cars on the other side, it will be difficult for cars in driveways to see them.
Now if Lower Downs Road were a major route, the current situation might be understandable. But the bottleneck is the tunnel under the railway, which is strictly single-lane. So having a nice wide road simply enables vehicles to get to the bottleneck quicker, where everyone gets very cross because it's a single lane where no-one has priority. What also happens on a regular basis is an overheight idiot get stuck in the tunnel causing chaos. Lower Downs Road was never designed for high volumes of traffic.Merton Council have allowed it to become a rat-run between Kingston Road and Worple Road to the detriment of the local community.
So what are they going to do about it? Merton Council are investigating punching a hole through the railway embankment, making a new tunnel to improve conditions for pedestrians 'and cyclists'. This would cost a fortune, and while it would improve conditions for pedestrians for about 10 yards, they will still have to walk along a busy rat-run with a footway unpleasantly narrowed by parked cars. It certainly won't do anything for cycling as cyclists will have to leave and rejoin the main carriageway at either end of the tunnel. I swear to you - Merton Council don't live in the real world. Thank goodness they'll have less of our money to waste in the coming years.
