Weser Tunnel, road tunnel
The Weser Tunnel is a road tunnel running beneath the Weser River in Lower Saxony, featuring two tubes with two lanes each for vehicle traffic. The passage stretches approximately 1646 meters in length, with its deepest point reaching about 40 meters below the water surface.
Construction began in 1998 and finished in 2003, with the tunnel opening to traffic in 2004 after workers pushed through multiple soil layers using specialized boring machines. The completion of both tubes marked a turning point in regional transport links, replacing the previous reliance on ferry services across this stretch of the river.
The tunnel accommodates only automobiles and trucks, with pedestrians and cyclists prohibited from using it. Occasional temporary closures can occur when fog develops or smoke detectors are triggered, requiring safety inspections before reopening.
This is the only fixed crossing of the Weser River north of Bremen and replaced multiple ferry routes, including the well-known Dedesdorf ferry. Some local ferry services continue to operate, still serving passengers seeking alternative crossing methods.
