On May 1, 2004, the day Poland joined the European Union, the Regulation of Minister of Infrastructure came into force, under which the movement of vehicles with a single axle load of up to 11.5 tonnes (25,000 lb) was allowed, at first on Poznań (Komorniki junction) – Konin (Modła junction) stretch. On November 15, 2005 the increased carrying capacity was extended to the entire length of national road 2,[3] which is still in force today.[4]
On the section constituting the Southern Bypass of Warsaw, between Konotopa and Warszawa-Lubelska interchanges, the route has the status of an expressway.
Over the years, the course of national road 2 through Warsaw was changed several times:

Near Mińsk Mazowiecki
Between the crossing with national road 17 in Warsaw and the junction with national road 50 in Stojadła the national road 2 was completely a priority road (19.4 kilometres (12.1 mi)). In 2011 alterations were made on this section – the traffic signals were installed and in Dębe Wielkie a roundabout has been built.
In August 2012 a motorway bypass of Mińsk Mazowiecki has been opened and the course of road 2 was assigned to that route. On December 17, 2012, by the ordinance of General Director of National Roads and Highways, the old route Choszczówka Stojecka – Mińsk Mazowiecki – Ryczołek (Kałuszyn) was renumbered as the national road 92.[12] In March 2021,[13] by the ordinance of General Director of National Roads and Highways, the section between crossing with national road 17 on the border of Warsaw and Zakręt and Choszczówka Stojecka was renumbered as the national road 92. From east of Mińsk Mazowiecki up to Siedlce (including bypass of the city), the road 2 is completely a priority road (over 50 kilometres (31 mi)).
