The 'Hloubené tunely Troja' tunnel project is part of a by-pass around Prague. This 6380m long stretch of road is being built to relieve traffic congestion in the centre of Prague. The two tunnel tubes were built one after the other. The Large-area Top 50 formwork elements were pre-assembled and supplied ready to use.
