The Pyhrnautobahn (A9) ('Pyhrn Motorway') is an Autobahn (motorway), in Austria. It runs through Alps by 2 two-lane tunnels: the 5,400-meter (17,700 ft) long Bosrucktunnel and the 8,320-meter (27,300 ft) long Gleinalmtunnel. The longest tunnel on the motorway is the 10-kilometer (6 mi) long Plabutschtunnel under Graz and its outskirts. The last section of the highway was completed in 2004.
While as of 2016 some section still remain only single carriageway, including some tunnels, work is progressing to make the Phyrn Autobahn fully dual carriageway. The second carriageway of the Bosruckstunnel was opened on Oct 19 2015; the Tunnelkette Klaus (8 km) and Gleinalmtunnel (8.3 km) – the last sections with a single carriageway – are planned to receive a second carriageway in late 2018 and in 2019 respectively.
