Local services in Glasgow
Glasgow has a large urban transport system, mostly managed by the Strathclyde Partnership for Transport (SPT). The city has many bus services; since bus deregulation almost all are provided by private operators though SPT part-funds some services. The principal bus operators within the city are: First Glasgow, McGill's Bus Services, Stagecoach West Scotland and Glasgow Citybus. The main bus terminal in the city is Buchanan bus station. The main M8 motorway passes through the city centre and connects to the M77, M73, and M80 motorways. The A82 connects the city to Argyll and the western Highlands. The M74 runs directly south towards Carlisle; the M74 completion scheme has extended the motorway from Tollcross into the Tradeston area to join the M8. Other road projects in the city include East End Regeneration Route, which aims to provide easier access to deprived areas of the East End by linking the M8 to the extended M74. The city has three international airports within 45 minutes travel of the city centre, as well as a centrally-located seaplane terminal. Two are dedicated to Glasgow while the third is Edinburgh International which, as it is situated on the west side of Edinburgh, is relatively close to Glasgow. These airports are Glasgow Airport (GLA) (8 miles (10 km) west of the city centre) in Renfrewshire, Glasgow Prestwick Airport (PIK) (30 miles (50 km) south west) in Ayrshire, Edinburgh Airport (EDI), (34 miles (50 km) east) in Edinburgh, and Glasgow Seaplane Terminal, by the Glasgow Science Centre on the River Clyde. There are also several smaller, domestic and private airports around the city. There is a heliport, Glasgow City Heliport located at Stobcross Quay on the banks of the Clyde.
