The tunnel, as a two-cell reinforced concrete frame, and an adjoining operations building are being built using the cut-and-cover method. Additional protection will be provided by shoring and noise barriers up to 6 metres high.
Our construction activities will begin in mid-2024 and the shell will be completed by mid-2028 so that traffic can flow on the new carriageway at the end of 2029. To ensure that existing traffic can be maintained without restriction during the construction period, construction will take place parallel to the carriageway.
Completion of the overall project to widen and rebuild the B 33 is expected in 2034.
