The most important of these is a 1.8km extension from Alte Poststrasse to Reininghaus in the south west of the city, which includes four new stops. Construction should start in 2019 the \u20ac44m extension is expected to open in 2021.\r\nIn the city centre, a 1km line will be built from Jakominiplatz to Annenstra\u00dfe via Neutorgasse and Belgiergasse to relieve the section along Herrengasse section. This stretch is currently used by all of the city\u2019s tram lines and is considered a bottleneck.

Construction will begin in 2020 and the extension will open in 2021.\r\nFinally, three single-track sections on lines 1 and 5 will be doubled. These include:\r\n\u2022 Zentralfriedhof - Puntigam (Line 5, \u20ac15m)\u2022 Hilmteich - Mariagr\u00fcn (Line 1, \u20ac6.3m), and\u2022 Mariagr\u00fcn - Mariatrost (Line 1, \u20ac2.3m).\r\nFor the first time, the province of Styria will contribute to the construction of tram extensions in Graz with a contribution of \u20ac43.8m.
