The B-10, also known as Ronda Litoral (Catalan: [ˈrɔndə lituˈɾal], Spanish: [ˈronda litoˈɾal]; English: Coastal Ring Road), is a 20-kilometre (12.43 mi) freeway in Catalonia, Spain partially encircling Barcelona passing through the eastern side of the city. It starts at Nus de la Trinitat interchange in northern Barcelona and runs along the entire length of the Besòs River and the city's coastline south to Nus del Llobregat interchange in Barcelona's southern suburbs, where it becomes the Autovía A-2. Both north and south end interchanges link the freeway to the B-20 or Ronda de Dalt, which encircles Barcelona passing through the western side, jointly forming a beltway commonly referred to as the rondes that surrounds the city. The freeway features a mix of below-grade, at-grade and covered tunnel sections, mainly as it passes through central Barcelona, where it is only two lanes in each direction while the other sections are three lanes. It becomes a segregated urban highway as it passes through central and northern Barcelona so that all its signposting becomes green and is maintained by the Metropolitan Area of Barcelona. In contrast, the southern section of B-10 is considered to be part of European route E90 and is signposted in blue following the formal colour scheme for motorways since it serves as a continuation of the Autovía A-2. In addition, unlike the rest of the route, this section is named Cinturó Litoral and is maintained by the Spanish Government. Although the speed limit is 80 km/h (50 mph) along the urban freeway section and 100 km/h (62 mph) along the interurban section, car's average top speed is lower due to traffic congestion as it serves as an arterial corridor to access Barcelona by road, and even average top speed may reach 20 km/h (12 mph) during rush hour. Additional restrictions for heavy goods vehicles are applied on the section situated between Montjuïc–Morrot and Rambla de Prim near Sant Adrià de Besòs, whereby weight limits is posted 12 tonnes and all vehicles over 12 meters long are banned from that section.
