The plan is to build a causeway between Riutunkari in Oulu and Huikku on Hailuoto Island. The causeway will replace the current ferry service. The causeway will be approximately 8.4 kilometres long, and it will consist of a road running on top of an embankment and long bridges in Huikku and Riutunkari.

A double-track railway is being built on the line Joutseno–Imatra, replacing the current single-track railway. The current track on the line Luumäki–Joutseno is also being improved. The project also comprises renovations to reduce the maintenance backlog on the Saimaa Canal Railway Bridge, the Mansikkakoski Railway Bridge and the underpass on the old Main Road 6.

The Finnish Transport Infrastructure Agency acts as a coordinator in six infrastructure development projects at the border crossing points of Raja-Jooseppi, Vartius, Parikkala, Imatra, Vainikkala and Vaalimaa funded jointly by the European Union and Finland. The projects will be implemented between 2019 and 2022.
