Full closure in the Hollmightunnel: Start important modernizations!

In the context of extensive modernization work, the Hollmightunnel in Neckargemünd from January 13 to February 28, 2024 is fully blocked. The beginning of the blocking is scheduled for Monday, January 13th, at 9 a.m. The aim of these measures is to increase security, efficiency and longevity of the tunnel.

The modernization work contains several essential points: the passage lighting is converted to LED, the video surveillance system updates and the central conducting technology is renewed. In addition, the emergency call system is adjusted to ensure reliable communication in an emergency. Tunnel security officer is Benjamin May from the Office for Road and Rady Construction in the Rhein-Neckar-Kreis district office. The inner -city diversions have already been signposted. Truck traffic is diverted via the federal road (B) 45 to Wiesenbach and the Kreisstraße (K) 4163 towards Neckargemünd Süd. Road users are also asked for an adapted driving style.

Details on the Hollmightunnel

The Hollmightunnel has a length of 385 m and crosses the old town of Neckargemünd. It consists of an approximately 200 m long mountain -driven section in the west and an equally long section in an open construction in the east. Connection options exist via Dilsberger Straße and in the west via a bridge to the B 45. Dilsberger Straße is a district road (K 4200) with low traffic, so that cars from Dilsberg can reach the old town without Schleich paths.

In addition, research into modern tunnel lighting systems shows that current lighting solutions in tunnels have numerous disadvantages. These are often mounted on the tunnel ceiling or high on the tunnel walls, which makes installation and maintenance complicated, lengthy and costly. In addition, longer closing times of the tunnel increase the risk of accidents, since insufficient lighting makes it difficult for road users to recognize the road limits. This can lead to the driver unnecessary distance to the tunnel edge, which further increases the risk of accidents. Other frustrating effects such as the "cave effect" or the "Christmas tree effect" with excessive lighting can also affect the security in the tunnel, such as lmtgmbh.de reported.
