New overhead cameras have gone up on the approaches to Tower Bridge with
signs mentioning camera enforcement. What are they enforcing? The 20mph
speed limit? If so, how - average speed over the bridge?

Not seen them, but if they look like a camera with two infra-red lamps
beside them, then they're probably SPECS cameras, which do exactly as you
suggest.

That's the ones. Looks like they're front-facing only though so anything
without a front number plate (eg motorbikes) will be immune...?
