This is Cromer St, part of a bike route south of Kings Cross station. It's been carefully designed to stop cars using it, by the insertion of a bollard; to stop motorcyclists using it, by the insertion of jagged flagstones; and to stop cyclists using it, by the insertion of a parking space right at the end.
This is actually a rare view of the facility without a car parked right on top of it - where the bicycle symbol is. Google's Street View shows it as it normally appears, with a car loading up on toilet rolls and 2-for-1 party packs of Mars bars from the shop to the side. Good to see that some businesses are weathering the recession.
