part of European route E85. The A2 motorway, connecting Vilnius with Panevėžys, is a part of E272. Other highways starting in Vilnius include A3, A4, A14, A15, A16. Vilnius's Southern bypass is road A19. Public transport The bus network and the trolleybus network are run by Vilniaus viešasis transportas. There are over 60 bus, 18 trolleybus, 6 rapid bus and 6 night bus routes. The trolleybus network is one of the most extensive in Europe. Over 250 buses and 260 trolleybuses transport about 500,000 passengers every workday. The first regular bus routes were established in 1926, and the first trolleybuses were introduced in 1956. At the end of 2007, a new electronic monthly ticket system was introduced. It was possible to buy an electronic card in shops and newspaper stands and have it credited with an appropriate amount of money. The monthly e-ticket cards could be bought once and credited with an appropriate amount of money in various ways including the Internet. Previous paper monthly tickets were in use until August 2008. The ticket system changed again from 15 August 2012. E-Cards were replaced by Vilnius Citizen Cards ("Vilniečio Kortelė"). It is now possible to buy a card or change an old one in newspaper stands and have it credited with an appropriate amount of money or a particular type of ticket. Single trip tickets have been replaced by 30 and 60-minute tickets. The public transportation system is dominated by the low-floor Volvo and Mercedes-Benz buses as well as Solaris trolleybuses. There are also plenty of the traditional Škoda vehicles, built in the Czech Republic, still in service, and many of these have been extensively refurbished internally. This is a result of major improvements that started in 2003 when the first brand-new Mercedes-Benz buses were bought. In 2004, a contract was signed with Volvo Buses to buy 90 brand-new 7700 buses over the following three years. An electric tram and a metro system through the city were proposed in the 2000s. However, neither has progressed beyond initial planning. In 2018 the Seimas of the Republic of Lithuania approved a new metro project with the president's agreement. In 2014 a mobile app was launched with public transport tickets on smartphones. In 2017, Vilnius started the historically largest upgrade of its bus services by purchasing 250 new low-floor buses. The project resulted in making 6 of 10 public buses being brand new
