Expressway S10 or express road S10 (in Polish droga ekspresowa S10) is Polish highway which, when completed, will serve as a direct route between Szczecin and Warsaw. It has been planned to run from the interchange with Motorway A6 on the eastern outskirts of Szczecin, through Bydgoszcz and Toruń, to the interchange with express road S50 near Płock, west of Warsaw. Its planned length is 460 km (290 mi).
As of 2024, only short stretches of S10 serving as bypasses of Bydgoszcz, Toruń and several smaller towns have been built, totalling about 56 km (35 mi). According to the plans, the road from Bydgoszcz to Toruń will be constructed by 2026, from Szczecin to Bydgoszcz – by 2030, and from Toruń to Warsaw – by 2032.[1][2]
Completed as dual-carriageway road mostly in expressway standard, but two intersections remain at-grade. They are planned to get reconstructed to full expressway standard by 2028.
Preparatory works. 1st carriageway of Wyrzysk bypass completed. 1st carriageway of Piła bypass completed with at-grade intersections and traffic lights (to be reconstructed during the addition of the 2nd carriageway).
