Hechtsheim motorway tunnel modernization: Less false alarms and traffic jams on the A60

improvements for Mainz-Hechtsheim: Modernization of the Autobahn tunnel

The tunnel of the A60 in Mainz-Hechtsheim is an important traffic junction, which has been closed again and again in recent years due to supposed fires. The sensitivity of the fire alarm system led to numerous false alarms, which led to kilometers of traffic jams on the A60 and in downtown Mainz. But now improvements are imminent that should significantly improve the situation for drivers and rescue workers.

intelligent technology to avoid false alarms

The fire alarm system in the Mainz-Hechtsheim tunnel reacts not only to actual fire, but also to hot exhaust gases from truck exhaust pipes. This led to unnecessary closures and trips from the fire brigade and the police. In order to solve this problem, Autobahn GmbH is now planning a modernization of the fire registration system. In addition to the temperature cables, other sensors are also to be installed that monitor additional parameters such as the concentration of carbon monoxide or visibility. Only when several sensors report a fire at the same time should an alarm be triggered. This is intended to significantly reduce the number of false alarms.

schedule for the renovation work

The elaborate renovation work at the Mainz-Hechtsheim tunnel should begin this year and are expected to take three years. In addition to the modernization of the fire registration system, further improvements are planned to increase security in the tunnel. With these measures, it will become less likely that there will be false alarms that affect traffic on the A60 and Mainz.
