Germany's B3 highway gets safety gates to curb closures

The Lower Saxony State Authority for Road Construction and Traffic has begun installing emergency gates (Nottoren) in the safety barriers on the Südschnellweg section of the B3 in Hannover. The gates are intended to prevent full road closures when heavy construction equipment, such as excavators and crane trucks, must pass. A brief closure is scheduled for Monday night from 22:00 to around 01:00, with detours signed in both directions.

The B3 is Germany’s longest federal road, running about 757 km from Buxtehude near Hamburg through Lower Saxony—passing Soltau, Celle, Hannover and Göttingen—into Hesse, Baden‑Württemberg and ending at the Swiss border near Weil am Rhein. It is often called the “German Route 66.”
