E20 passes south of the city, crossing onto Kastrup where it meets the Copenhagen Airport. Between Køge and Copenhagen, the road has three E-road numbers (also E47 and E55). The Great Belt Bridge and Øresund Bridge are both tolled. The Øresund crossing begins as a tunnel at Kastrup, which then transfers onto the bridge at the man-made island Peberholm. The road crosses the border between Denmark and Sweden on the Øresund Bridge. Sweden In Sweden, E20 is a motorway from the Öresund Bridge in Malmö to Alingsås 48 km northeast of Gothenburg, a long motorway. Furthermore, it is a motorway most of the route from Vretstorp (20 km (12 mi) west of Örebro) to Stockholm. The Swedish part of E20 is long. Its extent is shared with E6 along a long stretch, with E18 along and with E4 along . The part through Stockholm has very heavy traffic, including the most heavily trafficked road in Scandinavia, Essingeleden (160 000 vehicles/day). There is often congestion on this stretch. A new tunnel for route E20, "Norra länken", was built north of the city center and opened 30 November 2014. The planned Förbifart Stockholm bypass will divert traffic from Essingeleden. Between Stockholm and Tallinn a car ferry departs daily, taking 15 hours. The port in Stockholm is located at Lilla Värtan, about 4 km northeast of the central core of the city. A 21 km stretch of the E20 between Hallsberg and Örebro is planned to become by 2025 the first permanent electric road in Sweden. Estonia In Estonia, E20 follows the route of national main road nr. 1 (Tallinn–Narva). In Tallinn to relieve traffic a bridge has been built on the intersection of the E263 and the E20. The E20 across Estonia is partially an unsigned expressway (speed limit 110 km/h in summer), for 80.7 km east of Tallinn to Aaspere along with a section near Haljala (km 87 - 90.5) and a section between Kohtla-Järve and Jõhvi (km 155.9–163.2). The remainder being single carriageway. The distance from Tallinn to the Russian border at the Narva River is 218 km. Russia In Russia, the route takes the Narva Highway (also listed in the Russian road numbering system as the A180 route, formerly known as the M11 route) running from Ivangorod to Saint Petersburg as a dual-lane highway. The distance from Ivangorod to Saint Petersburg is 142 km. The border control facilities at
