Bridges are a great example of where average speed cameras can work, and as the 20mph limit on most of them is for protecting the fabric of the bridge as opposed to the users of it I guess there is a viable economic case for doing the others too.
I am aware of the Tottenham Court Rd scheme, but I'm not actually sure if it will work, and I don't like making cyclists share with speeding buses.
I can't think why they don't do the Strand though. At the moment it is so useless as a road that there's no point in leaving it open.
