Expressway S17 or express road S17 (pl. Droga ekspresowa S17) is a Polish highway which, when completed, will run from Warsaw through Lublin to the border crossing with Ukraine at Hrebenne/Rava-Ruska. As of 2024, 163 km out of planned 310 km are opened to traffic: the main section running from Warsaw through Lublin to Piaski, as well as bypasses of Tomaszów Lubelski and Hrebenne. The section from Piaski to the border with Ukraine is planned to get completed by 2028.

History

The joint section of S12 and S17, including the bypass of Lublin, was constructed in years 2011 – 2014. The section between Warsaw and Lublin was to be finished by 2015, but with subsequent reductions in government spending on infrastructure, the investment was delayed. The section was constructed in the design-build system starting late 2015 and early 2016, and the road was opened to traffic in 2019 and 2020. The road southeast of Lublin has smaller traffic density and received a lower priority, except for the bypass of Tomaszów Lubelski which was opened in 2021 (first carriageway only). Opening of the expressway between Piaski and Ukraine's border is expected from 2026 until 2028 depending on the section. In January 2024 contractors were selected to build two sections of the segment between Piaski and Zamość (16,6 km Piaski - Łopiennik ; 18,8 km Krasnystaw - Izbica ) with completion planned for 2027. Three sections between Zamość and Hrebenne are currently in the design stage of the design-build projects (Zamość Wschód - Zamość Południe, Zamość Południe - Tomaszów Lubelski, Tomaszów Lubelski - Hrebenne), with completion planned for 2026.

Sections of the expressway

Lublin bypass

In December 2009, the bidding process was started for the contracts to build the 66 km section of the road around Lublin, from Kurów to Piaski, which includes the city's east–west bypass road. The construction of this section started in 2010, with the first 13 km section to be opened to traffic in late 2012 and the rest in 2014. On this section, S17 overlaps with S12.

Warsaw eastern bypass

In Warsaw, the S17 expressway will serve as the eastern bypass of the city. Apart from the southernmost section from Lubelska to Zakręt, which was opened in 2022, the construction timetable is not yet set due to the environmental permit having been challenged in the courts.
