The Westhofener Kreuz is a motorway junction in North Rhine-Westphalia in the Rhine-Ruhr metropolitan region . It connects the federal highway 1 ( Heiligenhafen - Cologne - Saarbrücken ; E 37 ) with the federal highway 45 ( Sauerland line ; E 41 ).

geography

The motorway junction is located in the urban area of Schwerte in the Unna district , on the city limits of Dortmund . The closest districts are the eponymous Westhofen , Wandhofen and Holzen -Rosen, belonging to Schwerte, and Holzen and Syburg-Buchholz , in Dortmund. It is located about 10 km south of Dortmund city center, about 10 km northeast of Hagen and about 15 km northwest of Iserlohn . It is also located on the edge of the Sauerland , which the A 45 crosses in a southerly direction after leaving the cross. The Ebberg connects directly to the cross . The Ruhr is located around 2 km south of the triangle .

The Westhofener Kreuz has junction number 86 on the A 1 and number 9 on the A 45.

Design and state of development

Route during the renovation phase in August 2006

Since 2009 the A1 has been expanded to three lanes in both directions. In the direction of Bremen, the acceleration lane from the A 45 from Frankfurt was extended to approx. 1.3 km. Coming from Bremen there is a continuous 2.5 km long combined acceleration / unthreading strip from the Schwerte junction .

The A 45 is three lanes in the direction of Frankfurt. In the direction of Dortmund, the railway is two-lane and becomes three-lane when the distribution lane is inserted behind the cross. The complete three-lane expansion is urgently needed and is to be implemented in the next few years together with a renovation of the entire motorway junction. The direct connection ramps are two-lane, the indirect one-lane.

The motorway junction was laid out as a clover leaf , but is structured asymmetrically. The southern ear (A 1 from Cologne - A 45 to Siegen) is compressed because in this area, right next to the road, there is a Westhofen residential area behind a noise protection wall.

The cross is to be Template: future / in 5 yearsrebuilt by 2027 so that traffic on the A 1 coming from Bremen will be guided via a semi-direct ramp onto the A 45 to Siegen. From here, the A 45 is to be expanded to three lanes in each direction.

Traffic volume

The cross is used by around 187,000 vehicles every day. This high volume of traffic and day-to-day construction sites mean frequent traffic jams and delays.
