tourists/visitors to the city. West End The West End District, lying to the West of the Central zone, is the city's social and academic hub. West Street, the main thoroughfare in this area, is home to Sheffield's largest concentration of bars, clubs and restaurants and is heavily used by young adults, students in particular. Many university buildings are in this area, including many parts of the Sheffield Teaching Hospitals (although they mostly lie beyond the Inner Ring Road and thus do not constitute part of the City Centre). The Supertram also runs through this district, connecting it to the central zone and several other areas of the city. The Devonshire Quarter, on the southside of West Street, is a social and commercial hub, again especially for the young. It has seen a great deal of investment. The St Georges Quarter, right in the centre of the West End zone, is relatively small and focused upon the end of West Street as it meets the Inner Ring Road at Sheffield University Officer Training Corps home - Somme Barracks, main entrance is on Gell Street. New and future developments In recent years there have been numerous new developments in Sheffield City Centre seeing a large number of new additions to the skyline. Most of this work has been carried out under the guidance of the 'City Centre Masterplan 2008' and examples of its progress can be seen Tudor Square, Riverside, Castlegate and the Sheffield Digital Campus. St Paul's place is one of the most notable developments and features Sheffield's tallest tower. Riverside exchange and the West Bar combine to make a large business district on the north side of the city centre and are also home to legal and governmental offices. Sheaf Square and the Sheffield Station have also been heavily redeveloped and are due to see extras improvements in the next few years. In the West End area the University of Sheffield has invested in a number of new facilities and student accommodation and Sheffield Hallam University has greatly improved the area outside its main campus on Arundel Gate also. In late 2006, the "Connect Sheffield" scheme came into being. As part of this scheme, vehicle signage was improved by dividing the centre into four main areas (separate from the quarters) using electronic messaging panels with information about congestion and available parking and information about transport and visitor attractions.
