The federal highway 236 (abbreviation: B 236 ) is an approximately 210 km long federal highway that runs mainly through North Rhine-Westphalia , but also partly in Hesse . It begins in the Westphalian district of Coesfeld near Olfen and runs through the eastern Ruhr area as well as the western and southern Sauerland , mainly in the Lennetal , and ends in the Ederbergland in the northern Hessian district of Marburg-Biedenkopf in Münchhausen .
The B 236, which is mainly laid out in a north-west-south-east direction, begins east of Olfen on the B 235 , crosses under the Dortmund-Ems Canal and runs southwest through Selm and Lünen . Between Luenen and the city boundary Dortmund / Schwerte is the B 236 B 236n as highway-like expanded, with the Wambeler tunnel (length: 1.420 m) and the tunnel Berghofen (1.310 m), the largest single structures. In this area, the B 236 represents the Autobahn 441 planned in the 1980s . At Schwerte, the Ruhr valley is crossed before the road crosses a ridge. Here the Unna district is left and the Märkische Kreis begins. The B 236 between Schwerte-Ergste and Iserlohn-Letmathe has been closed to motorcyclists on Saturdays and Sundays, public holidays, and from Monday to Friday from 5pm to 10pm.
At Iserlohn - Letmathe , the B 236 descends into the Lenne valley. As a bypass of Letmathe and Iserlohn- Oestrich there is a swivel over the A 46 and a high bridge over Oestrich. The path leads through the Lennetal through Nachrodt-Wiblingwerde and Altena to Werdohl , where the B 229 runs a short distance on the same route. After Plettenberg , the Olpe district begins with the towns of Finnentrop and Lennestadt .
From Schmallenberg the B 236 reaches the Hochsauerlandkreis . In 1997 the Schmallenberg tunnel (235 m) was put into operation. Since then, the B 236 no longer runs through the historic town center of Schmallenberg. The Lennetal is left behind Schmallenberg.
In winter mountain located since 1995 as part of a bypass past leading to the city Herrlohtunnel (168 m) mounted on a common portion of B 236 and B 480 is located, and extending under the center Walt mountain tunnel (230 m).
The last place in North Rhine-Westphalia is Hallenberg . On the Hessian side it goes through the district of Waldeck-Frankenberg with the villages of Bromskirchen , Allendorf and Battenberg . The B 236 runs along Wollmar and ends in Münchhausen on the B 252 .
State of development
Most of the B 236 has one lane for each direction of travel. The motorway-like section between Lünen-Süd / B 54 and Dortmund-Aplerbecker Mark (southernmost section is no longer motorway-like) has two lanes in each direction.
In addition, there are some two-part sections:
- Lünen-Kurt-Schumacher-Ring (both directions)
- Bridge Datteln-Hamm Canal near Lünen to the connection to the motor vehicle road (towards the southwest)
- Schwerte to Schwerte-Freischütz (direction north)
- Iserlohn-Grüne to IS-Oestrich (direction north)
The Federal Transport Infrastructure Plan 2030 contains the following plans for the B 236:
- The section in Lünen between the Datteln-Hamm Canal or the railway bridge and the start of the motor road is to be completely expanded to 2 + 2 lanes (urgent need).
- The section between the Dortmund city limits (Aplerbecker Mark) and Schwerte ( ) is also to be completely extended to 2 + 2 lanes and is already firmly planned.
In addition, the Lenne bridge in Nachrodt is to be replaced by a new building and the main road is to be swiveled a few hundred meters to the north.
