the road that goes across it is called Viksängsleden. It is equipped with a bicycle and pedestrian path. E4-bron is a vertical-lift bridge, crossed by the eponymous E4 Motorway, and marks the southern fork with E20. It was built in the 1960s, together with the motorways around the city. Saltsjöbron was built in 2002 to relieve the E4-bron, and to provide an alternative in case of mechanical failure after one occurred in 1990. Parallel to Saltsjöbron and E4-bron lays the railway bridge predominantly used by local and freight trains. It opened in the summer of 2010, and is hence the youngest bridge in the city. It replaced the old railway bridge from 1921, which was located immediately east of the current bridge. The old bridge was replaces as it was unable to handle heavy trains, nor deep-going maritime vessels. It was also too noisy. The distance between the bridge pillars on the new bridge is wider, to enable the canal to be broadened further. The old railway bridge had a small pedestrian path. After it was demolished in autumn of 2010, pedestrians must cross at Saltsjöbron instead. The old railway bridge replaced an even older bridge from 1860 that crossed around the area of Tältet. That bridge was demolished in the 1920s, when Saltskog railway station had been closed and replaced Södertälje Södra railway station (subsequently renamed Södertälje Hamn). The Igelsta Bridge is the southernmost of the city's bridges. It is the main route for long distance and regional trains across Södertälje Canal. It is 2140 meters long, reaches as high as 48 meters above the canal, making it Sweden's tallest and longest railway bridge (after the Swedish part of the Øresund Bridge). Igelstabron spans between Pershagen and Hall. The bridge forms part of the Grödingebanan on the Western Main Line and opened in 1995. Södertälje Syd railway station is located on the bridge's eastern abutment. Church buildings Södertälje belongs to the Diocese of Strängnäs within the Church of Sweden. A total of eight church buildings are located within Södertälje. The oldest and most important to this day is Sankta Ragnhilds kyrka (English: Church of Ragnhild of Tälje) from the 1100s–1300s, which is located on the main square Stortorget. Further churches belonging to Södertälje parish are (St. Michael's Church) in Geneta, (Hovsjö Church) and (Lina Church) in Lina Hage. Lina kyrka was designed by Tallius Myhrman. It is renowned for
