Project Objectives/Outcomes:
The Crown Bridges Light Rail (Kruunusillat) project is one of the biggest infrastructure projects in Finland in recent years. When the projected is finished in 2027, a total of three new bridges, including a 1,200-metre-long bridge that will be the longest one ever built in Finland, will connect Helsinki downtown to the expanding suburbs of Laajasalo and Kruunuvuorenranta, shortening the travel distance from 11 km to 5,5 km. This new scenic route is designed for light rail and pedestrians only, encouraging people to use public transport and travel by bicycle.
Our Role:
Construction started in 2021 and Mincon’s drilling expertise has played a significant role, using Mincon’s patented Spiral Flush technology.
