There is a bus gate in Chelmsford causing mayhem and income, its situated close to a roundabout, is poorly signed and unless you are very local it will catch you out.
All it really needs is a no entry sign with an except for busses tag and it will work, however 37,000 fines in less than a year, common sense says the signage is inadequate and its an easy income stream, or is that too cynical?
