The Burgholz tunnel is a road tunnel in the area of ​​the city of Wuppertal . The tunnel connects the major road 418 (L 418) from the north of the city district Cronenberg located Theis Hahner cross with the Sonnborner cross , allowing a direct and continuous motorway link between the A 1 and A 46 via the Wuppertal southern hills . The tunnel runs through the Burgholz state forest and was opened on March 29, 2006 as the longest road tunnel in North Rhine-Westphalia to date . The breakthrough of the two two-lane, 1865 and 1787 meter long tunnels was already achieved in 2003 (tunnel breakthrough on September 23, 2003).

Planning and Importance

The reason for the construction of the tunnel was the following traffic problem: The A 46 crosses the northern part of Wuppertal and only then leads much further north onto the A 1 , which leads past Wuppertal to the east. For traffic heading south towards the A1, this meant a considerable detour. Therefore, this traffic moved largely through Wuppertal in the city. In addition, there was no efficient connection between the southern parts of the city, such as Vohwinkel with Cronenberg , Hahnerberg and Ronsdorf as well as to the city of Remscheid . This problem was to be solved by the motorway-like L 418, which touched the city south and was first planned in 1962.

The route of the road was problematic in parts because of the buildings there and for reasons of nature conservation. Therefore, the council of the city of Wuppertal rejected an above-ground solution that had already been planned and in 1989 decided to build what is now the Burgholz tunnel. According to current plans, the southern bypass should connect the Sonnborn motorway junction of the A 46 via the L 418 and state road 419 (L 419) with a new junction to be built on the A 1 near the existing junction 94 (Wuppertal-Ronsdorf). At the beginning of the seventies, the L 418 already existed near Sonnborn .

Construction of the privately financed tunnel began at the beginning of 2002 (the tunnel was stopped on July 5, 2002), and was completed in mid-February 2006. It was opened on March 29, 2006, and opened to traffic one day later. With a planned 40,000 vehicles per day, the tunnel is supposed to relieve the Wuppertal city center, the Kiesberg tunnel , the A 46 north in Wuppertal and the A 1 east of Wuppertal. However, the corresponding travel times have already been significantly reduced.

Topography and structure

For reasons of environmental protection, the tunnel construction was preferred to an above-ground variant and runs below the Burgholz state forest, which should not be cut by road construction due to its rare tree population. Due to the incline overcome in the tunnel structure and the fact that there are only three meters of earth above the tunnel, the construction of the tunnel was technically demanding. With a complex emergency call and monitoring system and six cross connections at a distance of around 266 meters between the tubes and emergency booths at a distance of around 133 meters, the tunnel meets high security requirements. 84 permanently installed video cameras transmit the traffic situation to the control center.
