Construction of the Riederwald Tunnel - Last Trees Felled - Hesse's €1.5B Riederwald Tunnel breaks ground after decades of delays

Workers have begun felling the last trees in Fechenheim Forest to make way for the Riederwald Tunnel. The operation marks a key step in Hesse's largest urban infrastructure project, now valued at €1.5 billion. Police reported no disruptions as clearing started peacefully.

The tunnel project has faced legal challenges but moved forward after the Kassel Administrative Court rejected an emergency injunction in February. Judges ruled that the tunnel served public interest by closing a long-standing gap in the road network. They also approved measures to protect the endangered Heldbock beetle, including relocating breeding trees.

Planning for the tunnel began over 35 years ago, with formal approvals dating back to 1989. Construction is set to last seven years, starting in January 2026. The west portal should finish by late 2028, followed by the east portal phase. Completion is not expected before 2033.

Police were present during the tree-clearing but noted no protests or activists at the site. Authorities confirmed the operation proceeded smoothly from the start.

The Riederwald Tunnel will connect the A66 and A661 motorways, addressing a missing link in the region's transport network. With legal hurdles cleared and construction underway, the project now enters its long-awaited build phase. The final cost remains at €1.5 billion, with no further delays reported.
