Maintenance work in the Warnow Tunnel: Single-lane travel until September 5th!
One actually thought that the streets in Rostock would be in full bloom again after the long summer vacation. But now things are getting a bit tight! From September 1st to 5th, 2025, only one lane will be available in both directions in the Warnow Tunnel. The reason for this is scheduled maintenance work that is regularly necessary to ensure the safety and functionality of the tunnel technology. This reports Northern Courier.
The maintenance work is nothing new: it takes place once a year and is used to check and repair technical systems and the roadway. The quality of safety in a tunnel is absolutely crucial and every effort is made to maintain this. In order to make the flow of traffic as smooth as possible, traffic will be directed in the opposite direction through a tunnel tube during the work.
What can drivers expect?
Drivers traveling towards Warnemünde and the Baltic Sea should prepare for a change in traffic routing. The tunnel signage will be updated accordingly so that no one gets stuck in traffic. After all, the Warnow Tunnel, which opened in 2003, is an important transport route for the region and recently enabled the 90 millionth vehicle to pass through. This makes it clear how high the traffic volume is and how important this measure is.
We ask all road users to understand the temporary restrictions. Every effort is being made to complete the maintenance work as quickly and efficiently as possible so that the tunnel can soon be used in its full glory again. Anyone heading out on the road should have a plan B in place to avoid potential delays.
Further details about the maintenance measures can be found on the website Warnow crossing to find. Not only is the time frame clearly outlined here, but the importance of maintenance for the safety of all road users is also emphasized. It is important that we focus on safety - because safety comes first!
