Roertunnel

The Roertunnel is a 2.45 km long land tunnel in Roermond, Netherlands. Opening in 2008, it is one of the longest land tunnels for road traffic in the Netherlands.The tunnel is a part of the A73-south highway, connecting the A73-north in Venlo to the A2 near Echt. The tunnel consists of two main tubes, each containing two traffic lanes without shoulders. One tube contains northbound traffic, while the other contains southbound traffic. Additionally, there is a third tube between the two main tubes that functions as an emergency escape route. The maximum speed inside the tunnels is 100 km/h. Since the highway is directly in the path of urban and protected environmental areas in Roermond, the tunnel has been constructed to lead the traffic underneath East Roermond's urban area, the Roerdal environmental protected zone, and the Roer river.
