As far as I'm concerned, this post from Two Doctors puts the case against building another Forth Road bridge about as succinctly as it's possible to do. If there was any justice, that single blog post would convince the SNP, LibDems, Labour and the Tories that it's the biggest, dumbest transport vanity project ever conceived of, well since the M74 motorway extension. And that would be the end of it.

Sadly it isn't.

It must be a little embarrasing for the SNP in Holyrood to discover that the three local authorities most affected by the project, two of which include SNP members in the executive, are working out how to lodge formal legal complaints about the proposals for the new bridge. And why? Because they know the new bridge will generate vast quantities of traffic, because the new bridge is simply a road - with no investment proposed in public transport. The Scotsman reports:

Councillor Gordon Mackenzie, Edinburgh City Council's transport leader, said: "While I welcome the publication of the bill, we need a firm commitment from the Scottish Government that a focused public transport strategy will be developed.

"Spending over £2bn to have the same traffic queues, or worse, is not a sensible position."

When will the LibDems, Tories, and Labour join the Greens in opposing this farce of a project?
