[3] The last segment to the Belarusian border (32 km (20 mi)) is under design, but its planned construction has been postponed due to the Russian invasion of Ukraine.

New plans to build the A2 motorway were seriously formulated in communist Poland in the 1970s, possibly with the goal of completing it in time for the Moscow Olympics in 1980.

Construction of another stretch (between Łódź and Warsaw) was started and then abandoned, leaving an interesting ruin informally named Olimpijka, which was in turn demolished around 2010 when building of the motorway resumed.

This section is a toll road, with the exception of a short stretch through Poznań which serves as that city's bypass (between the interchanges at Głuchowo and Kleszczewo).

The 90 km (56 mi) section from Stryków to Warsaw was to be built in a public-private partnership, but the negotiations between the government and private companies interested in participating collapsed in February 2009 due to disputes over financing terms.

This goal was an ambitious one and ultimately proved challenging, given the possibility of unexpected delays during construction[13] and the fact that the Chinese consortium abandoned the project less than a year later,[14] so that new contractors had to be selected to replace it.

The goal was to have this motorway stretch provisionally opened to traffic in time for Euro 2012, even if it is not fully completed, with various restrictions such as a lower speed limit to ensure safety.

For a while it was not clear whether even this limited goal would be reached, but the motorway opened to traffic in June 2012 after very intensive construction work in the final few months.

[17] After COVEC withdrew from completing its construction of the A2, Bank of China was to pay a performance guarantee to the Polish government's roads organization GDDKiA.

[18] The eastern section from Warsaw to the border crossing with Belarus at Kukuryki near Brest (connecting with M1), about 170 km (110 mi) in length, is largely under construction.

[21] The longest section from Mińsk Mazowiecki to Biała Podlaska (101 km (63 mi)) is in realization (design-build contracts) and is planned to get completed by 2024.
