I wonder about whether the Silvertown Tunnel will make the average traffic worse but the worst case traffic better. Currently, if the Blackwall tunnel closes, traffic basically grinds to a halt across a huge part of SE London. I was taking my dying bunny to the vet the other month and a trip that normally takes under ten minutes took forty due to the Blackwall tunnel being closed, even though I'm all the way back in Hither Green. Nevertheless, I would have preferred they built one of the many proposed pedestrian/cycling bridges...
