Frei Zimmer has implemented road aesthetics on the E18 motorway between Koskenkylä and Vaalimaa in co-operation with consultants from Ramboll and Sito. Designing and construction of the motorway has been divided into two stages: Koskenkylä-Kotka and Hamina-Vaalimaa.
The implementation of the road aesthetics is based on a plan that was drawn up back in 2009. Programmes for both stages have been drawn up.
Koskenkylä-Kotka was completed in 2014 and Hamina-Vaalimaa in 2018.
