National road 50 (Polish: Droga krajowa nr 50) is a route belonging to the Polish national road network. The highway forms a part of bypass of Warsaw metropolitan area, running from 29 to 84 km away from centre of Warsaw. The route has two bridges over Vistula, one in Wyszogród and another in Góra Kalwaria.
Because of the heavy traffic (road is used as a detour for trucks due to restrictions in Warsaw), the highway was completely reconstructed and has a few bypasses along major and smaller towns.
See main article: A50 autostrada (Poland). A new parallel route from the Central Airport to Mińsk Mazowiecki is planned as the A50.
See main article: Expressway S50 (Poland). A new route with expressway status is planned from the Central Airport via Sochaczew, Wyszogród and Radzymin to near Mińsk Mazowiecki. Together, the planned A50 and S50 will form a new ring road around Warsaw, replacing the current ring.
