19-444: The first part of the current line to Alléparken was opened in 1914, following the construction of a pontoon bridge across Tranebergssund . The line was then gradually extended westwards, reaching the current terminus at Nockeby in 1929. To the east, the line ran to Tegelbacken in central Stockholm. The pontoon bridge was replaced in 1934 with the new Tranebergsbron . Planning for a Metro system started around this time, and in 1944

38-456: A Centralbron was therefore substituted by a temporary solution, by its customers dubbed Slingerbultsleden ("The Dodge Route"), criss-crossing the western streets of Gamla stan using two temporary bridges crossing Riddarholmskanalen to open out on Vasabron . While the metro system and Centralbron were being constructed Slingerbultsleden had to be scrapped, and in 1953 it was substituted by a 240-metre-long (790 ft) pontoon bridge connecting

57-455: A capacity for 130,000 cars per day. It is paralleled by the bridges ( Södra and Norra järnvägsbron ) and the tunnel of a two-track railway used by the commuter and freight trains . Centralbron does partly go on top of the Metro which opened on this stretch 1957 and planned together with the bridge. Nearby bridges include Riddarholmsbron , Vasabron , Strömsborgsbron , and Hebbes Bro . Since

76-408: A maximum span of 33.7 metres. The continuous steel girders of the roadway are resting on concrete pillars firmly anchored to the soil by numerous poles. To the south, another two spans are stretching some 46 metres over Söder Mälarstrand ("Southern Shore of Lake Mälaren") before three smaller spans hands the roadway over to Söderledstunneln ("The Southern Route Tunnel"). To the north, the bridge

95-492: A truly 'central' bridge. An eastern route is as of 2008 not a timely topic, for several reasons but particularly because of the Royal National City Park taking up most of the area east of the city, thus making such a route infeasible. There is however a Western Bridge . The realization of the northern bridge stretching over Norrström had to be postponed until the enlargement of the traffic junction at Tegelbacken

114-428: Is a major bridge in central Stockholm , Sweden , connecting the northern district Norrmalm to the southern Södermalm . It is 1,200 metres long and consists of two viaducts passing over Söderström ("Southern Stream") and Riddarfjärden close to Norrström ("Northern Stream") with an interjacent elevated section traversing Riddarholmskanalen and the adjacent eastern waterfront of Riddarholmen . Centralbron has

133-451: Is continuous with a 173-metre-long (568 ft) viaduct passing over the Gamla stan metro station , opened 1957. The viaduct is made of a concrete roadway resting on steel girders. The entire structure was completed and inaugurated June 16, 1959 and the name 'Centralbron' made official by a naming committee that assumed a Österbron ("The Eastern Bridge") would be built, thus making Centralbron

152-595: The Brommadepån  [ sv ] depot at Alvik via tracks to the west of the station. These are shared with the metro (which uses reversing sidings in the depot for trains terminating at Alvik), and therefore are electrified with both overhead lines for trams and third rail for the Metro. Tegelbacken Tegelbacken is a junction at Norrmalm in Central Stockholm and the name of several streets that contains

171-465: The cross-platform interchange provided to change to the Stockholm metro green line (lines 17, 18 and 19), or they can change to Tvärbanan (line 30 and 31) at lower level platforms. The tramway is separated from roads, but has some level crossings . The journey time from Alvik to Nockeby is 14 minutes, with service intervals varying between 6 minutes in the morning and evening peaks, and 20 minutes during

190-497: The Ängbybanan route was built from Alvik to Åkeshov (and later Islandstorget ), operated initially with trams but designed as a grade-separated route for later conversion. Conversion happened in 1952, forming the western section of the present-day Stockholm metro Green Line. Consequently, the Nockebybanan was cut off from running into the city and became a feeder route for the Metro at Alvik. Nockebybanan and Lidingöbanan were

209-446: The 1960s traffic increase. Over the years, Centralbron together with a suggested additional railway track have been much criticized and debated because of their unwieldy and rumbling presence in a delicate historical setting. Lately, the construction of a tunnel to replace them has been suggested. The cost of such a tunnel, several billion kronor, has put this on hold without any time set. A new metro tunnel has also been suggested because

228-517: The evening and weekend. Typical weekday traffic is around 11,800 boarding passengers (as of 2019). The line is served by 30 meter long Flexity Swift trams. The depot and traffic control center at Alvik are shared with Tvärbanan. As of 2018, new CAF Urbos trams (A35) were ordered for the Tvärbanan extension to Solna . But after Tvärbanan modernisation (23/3 to 2/10, 2017) all A35 were put on whole Tvärbanan , 28% are A35 and 72% are A32. Trams access

247-465: The first decade of the 20th century, numerous proposals labelled "Centralbron" had been produced and more than 20 of them scrapped before the elaboration of the general plan of 1928. During the 1930s the need for a "central bridge" crossing Gamla stan , the old city, declined due to the realization of the plans for a western traffic route, Västerbron , and the clover-shaped traffic junction at Slussen , both finally inaugurated in 1935. In 1930 plans for

266-506: The junction. At Tegelbacken, the traffic are connected to the Centralbron , Vasabron , Nynäsvägen and Gamla stan . 59°19′42″N 18°03′41″E  /  59.3283°N 18.0614°E  / 59.3283; 18.0614 This Stockholm road or road transport-related article is a stub .

285-533: The northern end of the now non-existent Riddarholmskajen ("Quay of Riddarholmen") to Klara strand . Its 7 metres wide roadway had a maximum capacity of 20,000 cars per day and remained in use until the completion of the northern bridge in 1967. WW2 further delayed any attempts to elaborate a permanent solution, but in 1947 a decision to build a southern bridge crossing Söderström was taken, and work finally begun in 1950. The 189-metre-long (620 ft) and 21.3-metre-wide (70 ft) bridge stretches over six spans with

304-455: The only tram lines in the Stockholm region not to be withdrawn in conjunction with the switch to right-hand traffic in 1967. Since the line does not run on the street, and was simple and self-contained, and bi-directional rolling stock was available from the pre-metro tram lines, it was easier to convert to right-hand running than the rest of the network. Trams now run on the right from Nockeby to

323-409: The penultimate station at Alléparken, where they cross over and run on the left into Alvik, permitting cross-platform interchange with the Metro. By the 1990s, the line and rolling stock was in a poor state of repair and was widely expected to be dismantled and replaced with bus services. In 1975, the line had been re-numbered from 12 to 120, matching the numbering scheme used by local buses. The number

342-488: Was resolved in 1961. The bridge, finally inaugurated September 3, 1967, is a 246-metre-long (807 ft) and 22.3-metre-wide (73 ft) reinforced concrete structure with an average span of 19 meters. To the north, it makes a sharp turn to the west where it extends over the railway, and connects to Klarastrandsleden . The bridge over the railway replaced a level crossing nicknamed Tegelbackseländet ("The Tegelbacken misery"), since it created long traffic jams as an effect of

361-557: Was reverted back to 12 later. However, a concerted local campaign saved the line and from June 1997 to June 1998 the line was closed and renovated, and new Bombardier Flexity Swift (A32) trams were introduced from 1999. A running race in the surrounding neighbourhoods, Tolvanloppet takes both name and distance (12 km) from the line number. Nockebybanan has a single line (line 12) with ten stops, running from Nockeby to Alvik in Bromma borough . At Alvik metro station , passengers can use
