shopping mall (1999). Beside them, there are many small and bigger shops, stores on its either side, and mostly turn-of-the-century residential buildings above them. Transport Metros The four metro lines have five stations on Nagykörút, at the junctions of the above four roads: (from north to south) Nyugati pályaudvar (M3), Oktogon (M1), Blaha Lujza tér (M2), Rákóczi tér (M4) and Corvin-negyed (M3 again). 4 and 6 trams A characteristic vehicle of the Grand Boulevard is the tram no. 4 and 6, reaching Buda both in north (Széll Kálmán tér) and south Újbuda-központ (line 4) and Móricz Zsigmond körtér (line 6). The line dates back to 1887 and it has since extended to 8.5 km in length and 21 stations to become the busiest tram line of Europe, carrying 200,000 travellers a day. (The routes of tram lines 4 and 6 differ only in their last two stops in the south.) Its trams (no. 4 and 6), a unique type in Budapest, have been replaced by low-floor Siemens Combino Supra vehicles, the longest in Europe (54 m), after July 1, 2006. Tram stations were elevated and in places widened and modernized, ramps added, the electric cables renovated and some rail sections replaced during the reconstruction, which cost altogether 3.4 billion forints. Further ring roads in Budapest There are three further ring roads in Budapest: the Small Boulevard (Kiskörút), with the length of about 1.5 km, inside the semicircle of Nagykörút (including Károly körút, Múzeum körút and Vámház körút), the Hungária körgyűrű, an even bigger ring road outside Nagykörút (approx. 13 km), which is not always thought of as a single entity (it includes Róbert Károly körút, Hungária körút and Könyves Kálmán körút). the M0 motorway, which encircles the three-quarters of the metropolitan area, connecting motorways M1, M7, M6, M5, M4 and M3.
