The task of its scope includes, among others, the construction of a new bridge in place of the existing one located in kilometre 190+859 of the national road Noteć river in Ujście (Pilskie County, Greater Poland Voivodeship).

The investment envisages the demolition of the existing facility and the construction of a new structure in its place when carrying out traffic by a travelling bridge.

As a result of the expansion, the facility will gain a higher load capacity class and improve the performance of the crossing, among others, thanks to its expansion with walking and bicycle. Equipment elements of the new structure, in particular road safety barriers, will improve safety and improve the comfort of users.
