Versorgungshausstraße (line 2) via the Fürbergstraße to the Fadingerstraße was built in the spring of 2006. Especially during events in the city centre, and during the UCI Road World Championships 2006, it has been used intensively. Since then, the trolleybuses of lines 2 and 4 have operated on and off over this route. This section was the basis for the later electrification of the former Albus line 20. Also, until September 2006 the Gaswerkgasse / Ignaz-Harrer-Strasse intersection, and the Hauptbahnhof area around the Forum-Kaufhaus/Fanny-von-Lehnert-Straße, were provided with additional turning and reversing capabilities. Likewise, since the spring of 2007 a non-revenue section has been in operation from the Landeskrankenhaus (line 7) to Willibald-Hauthaler-Straße (Line 4), and an additional turning space has been provided at the Makartplatz, in front of the Holy Trinity Church. A new turning facility on the Aiglhofkreuzung from line 4 to line 2 was created in spring 2008, as well as a dedicated lane for trolleybuses in the Griesgasse in the city centre. The latter allows the stacking-and-demand retrieval of trolleybuses in the city centre for events. With the timetable change on 7 December 2007, line 4 was extended from Langwied over the city boundary to Mayrwies, replacing bus line 4A. In autumn 2008, the Salzburg Municipal Council decided to electrify the branch of bus line 20 to Sam / Lankessiedlung. The route follows that of line 20 from Lankessiedlung, via the Salzburg-Gnigl S-Bahn station, Fuggerstraße, Volksgarten, Hanuschplatz to the Landeskrankenhaus; the line leads back to Hanuschplatz and to Sam, via Edward-Baumgartner-Straße and Karajanplatz. This work was completed in mid-2009, and bus line 20 became trolleybus line 10. On 9 July 2009, lines 3 and 5 were extended by to the new Itzling Pflanzmann terminus. These were the first privately financed trolleybus sections in Salzburg. Lines The eleven lines of the present Salzburg trolleybus system are as follows: Projects In October 2010, plans for new extensions were presented. It is proposed to run line 10 through the Strubergasse in future, and thereby provide a better connection with the Struber barracks. Additionally, by means of a branch in the Karolingerstrasse, line 8 will serve the many businesses and residents in that district. The city of Salzburg plans to invest around €2.2 million in these two projects up to 2015. For quite some time, an extension to Eugendorf, or a cross-border line to Freilassing in Germany, have also been discussed.
