 The Tyne Gorge, between Newcastle on the north bank and Gateshead—a separate town and borough—on the south bank, is known for a series of dramatic bridges, including the Tyne Bridge of 1928 which was built by Dorman Long of Middlesbrough, Robert Stephenson's High Level Bridge of 1849, the first road/rail bridge in the world, and the Swing Bridge of 1876.Large-scale regeneration has replaced former shipping premises with imposing new office developments; an innovative tilting bridge, the Gateshead Millennium Bridge was commissioned by Gateshead Council and has integrated the older Newcastle Quayside more closely with major cultural developments in Gateshead, including the BALTIC Centre for Contemporary Art, the venue for the Turner Prize 2011 and the Norman Foster-designed The Sage Gateshead music centre.The Newcastle and Gateshead Quaysides are now a thriving, cosmopolitan area with bars, restaurants and public spaces.
