2000-Today Trunk Routes The trunk routes were created in 1995 as part of an attempt to create a bus rapid transit system in Athens. They actually were renamings of existing routes in order to have a common special numbering based letters and a common number when using the same street to exit the city centre. For example, all routes using the number 8 (A8, B8, Γ8) are passing from Patission street with a common start at Polytechneio. There were also express routes, whose name started with the letter E, that were special express rush-hour alterations of the A-lettered route of a certain line (for example route E7 followed the exact same path as route A7, but it was not calling on some stops). The main goal of these lines was to remove a vast number of bus routes from the Athens city center, which was heavily affected by traffic congestion at the time. With the creation of trunk routes most of the bus routes were relocated in suburbs. For example, routes "538 Kanigos-Kifissia and "508 Kanigos-Agios Stefanos" used to have a common start at Kanigos Square and then followed Kifissias Avenue until Kifissia, where 538 was turning in Kifissia whilst 508 continued further north to Agios Stefanos. After the trunk route system these routes were renamed to "A7 Kanigos-Kifissia" and "508 Kifissia-Agios Stefanos". Many routes like 508 had their starts moved to suburbs where a trunk route finished. This scheme was created only for distant suburbs of Athens such as Agios Stefanos, Vouliagmeni, Paiania, Ano Liossia and Mandra. In suburbs near the city centre, such as Ilioupoli, Vyronas, Psychiko and Galatsi, there was not any factual change on the bus routes. The routes initially had a distinct colour for each line but after 1998-1999 they practically had no difference from a normal bus route. These routes were heavily overshadowed by the metro system after its opening in 2000. In 2007, after the metro extension to Egaleo opened, the metro system had practically taken over the role of a trunk route. After 2011, when ETHEL (Athens Bus Company) and ILPAP (Athens Trolleybus Company) merged to avoid bankruptcy (both companies were heavily affected from the financial crisis) and formed OSY, many of these routes were discontinued and they were completely replaced by the metro system. Today only 19 of the 45 initial trunk routes are still in service (not counting the express routes), while only 17 have a trunk route role (routes B2 and B12 have been localised but they still use the trunk route numbering system).
