Construction of the Biskupia Górka viaduct and reconstruction of Trakt st. Wojciecha, Zaroślak, Okopowa, Nowe Podwale Grodzkie, Augustyńskiego and Toruńska streets is one of the most anticipated investments recently. The modernization of the road system connecting Śródmieście with the southern districts of Gdańsk and the national road No. 91, running to the south of Poland, was aimed at improving communication and increasing the transport accessibility of the city and the seaport.

As part of the investment, the old road viaduct was demolished and a new one was erected in its place. Two lanes of the viaduct have already been opened, and in the next stage of the works, bus lanes running in both directions will be commissioned. Both on the Biskupia Górka viaduct and on the routes leading to it, ELDRO installed traffic lights along with ITS system devices, which significantly increase road safety.
