Leeds city centre is contained within the Leeds Inner Ring Road, formed from parts of the A58 road, A61 road, A64 road, A643 road and the M621 motorway. Briggate, the principal north–south shopping street, is pedestrianised and Queen Victoria Street, a part of the Victoria Quarter, is enclosed under a glass roof. Millennium Square is a significant urban focal point. The Leeds postcode area covers most of the City of Leeds and is almost entirely made up of the Leeds post town. Otley, Wetherby, Tadcaster, Pudsey and Ilkley are separate post towns within the postcode area. Aside from the built up area of Leeds itself, there are a number of suburbs and exurbs within the district.
