Silvertown Tunnel campaign needs your support

I assume the logic behind this tunnel is that Greenwich is so jammed because of people trying to get over the river to go east and the tunnel will enable them to do that more efficiently. I doubt it because the problem is really caused by Greenwich being in the way. If you start a 3rd tunnel there it will only get worse. The answer is to build a river crossing further down that is accessed by something that bypasses the central bits of London.

Not doing anything is not an option, and the campaign is missing the point by assuming that the problem is private cars. This is central London, and maybe 70% of the problem is more like commercial traffic of various sizes, minicabs, black cabs and buses. Therefore a solution should be found that reduces or removes our reliance on that. If you care about pollution then the solution is to ban diesel and phase in LPG and LPG-hybrid vehicles. If you care about traffic volume then you need to look at moving deliveries to nighttime, incentivise working from home, increase river transport, build a Thamesside monorail or something, etc.

Incidentally I'm not sure about the logic displayed here:

The building of the second Blackwall Tunnel in the late 1960s saw traffic double within a year – and its new approach roads were jammed within a decade. The Silvertown Tunnel would be no different.

Because didn't that co-incide with a huge boost in Britain's prosperity, the availability of affordable cars and finance to pay for them, people relocating to the suburbs and overspill towns and all the rest of it. It's correlation rather than causality. I'm sure studies show it, but do they normalise it to eliminate economic and societal factors?
