Roschier represented the largest lender, European Investment Bank, in the 20 year PPP road financing of the final phase (Hamina-Vaalimaa) of the E18 motorway, crossing the country from Turku to the eastern border and constituting the core of the Scandinavian-Mediterranean Network Corridor. The new road section to be built from Hamina to Vaalimaa comprises 32 kilometers and includes the building of a waiting area for heavy vehicles at Vaalimaa. Designed as a green motorway, the project will help reduce traffic congestion and increase safety in the area.
 
The total value of the agreement is 378 million euros. The construction work began immediately after the finalization of the documentation on 9 June and the motorway will be opened to traffic in spring 2018.

This is the first Finnish PPP road Project since 2011 and the fourth ever in Finland. Previous PPP road projects have been the E4 Järvenpää-Lahti motorway, the E18 Muurla-Lohja motorway and the E18 Koskenkylä-Kotka motorway. Roschier has advised either the winning consortium or all or part of the financiers in all four.
