Roads filed under BS21

Named roads first, then numbered ones. A road is filed under one district even where it runs through several, so a street missing here may be listed under a neighbouring district — which is why the address lookup never calls a British street absent. Great Britain has no open register of buildings, so a listed road never means a building on it exists.

That the address lies in the BS21 district of the BS (Bristol) postcode area, and the place OS Open Names most often lists first for its postcodes is Clevedon.
