I've also been thinking about the patch where you have to cross St Thomas St to get to the Bermonsey St Tunnel - that can be difficult to cross in the mornings with traffic coming from two directions. You're basically dependent on the time lag between the lights changing on both sides to get across.
Yes, another potentially dangerous spot. I also think it would be good to have one on Long Lane, opposite City Walk and Wilds Rents - where one can stand for up to 10 minutes, just waiting to cross - getting very wet on rainy days from both above and below!
There is a long gap between the two nearest crossings, and it would reduce the regular speeding on Long Lane, and also reduce being regularly Tsunamied.
This leads to poor planning for the area (see the protracted arguments over Bermondsey Street) and means the needs of the area's real residents are not of primary concer to the planners.
I fully garee the junction at Leathermarket Street/TannerStreet/Bermondsey street is awkward and could be dangerous. The problem is that so many people use Tanner Street as a cut through for this area, with flows both East and West. If it was made 1 way with no entry from Tower Bridge Road traffic flows would reduce considerably and the risk at the juction on Bermondsey Street would be greatly reduced.
As for a crossing on Long Lane at City Walk/Wild Rents i think that would be a great idea, and cause very little interference for all users of the road.
As to Tanner Street becoming one way, I would disagree on the basis that there would be no alternative for traffic coming from Tower Bridge trying to get into the Bermondsey Street area, they would have to go all the way to Bermondsey Square just making that area even busier. In other words making it someone else's problem. That seems a bit Nimby for me.
I like the approach of other countries where all the traffic, pedestrian and vehicular share these crowded areas with low speed limits and without defined pavements or crossing points. This novel approach seems to slow the traffic right down.
There is a crossing further up from City Walk towards Bermondsey Street but it is quite a way to walk just to cross the road. Many people use City walk as a cut through and you see lots of people trying to cross here so I think a crossing is long overdue. Sadly what normally happens is southwark Council react rather that are proactive so until something nasty happens (God forbid)at any of the sites mentioned nothing will probably change.
