The Bottrop motorway triangle (abbreviation: AD Bottrop ; short form: Bottrop triangle ) is a motorway triangle in North Rhine-Westphalia in the Rhine-Ruhr metropolitan region . It connects the federal freeway 2 ( Oberhausen - Hanover - Berlin ) with the federal freeway 31 ( Emden - Oberhausen).
Geographical location
The motorway triangle is located in the northern Ruhr area in the city of Bottrop . The closest districts are Eigen and Grafenwald (City of Bottrop) and Ellinghorst (City of Gladbeck ). It is located on the southern edge of the Hohe Mark-Westmünsterland Nature Park , about 15 km south of Dorsten , about 10 km northeast of Oberhausen and about 10 km northwest of Essen . Immediately west of the triangle is the Franz Haniel colliery .
The Bottrop motorway triangle has junction number 3 on the A 2 together with the exit of the same name and number 42 on the A 31.
history
The motorway triangle was opened to traffic in 1987 together with the section between the Bottrop triangle and the Kirchhellen-Nord junction.
Originally, the A 31 was to be extended further south beyond the Bottrop triangle. A route via Mülheim , Essen-Werden and Bergisch Gladbach to Bad Neuenahr-Ahrweiler was planned, but was stopped by a Mülheim citizens' initiative. This explains why the triangle was built so generously: the lanes of the A 31 are drawn far apart for the southern extension and between the connecting lane of the A 2 in the direction of Oberhausen to the A 31 there is space for another ear. Originally, the motorway triangle was also called the Bottrop motorway junction .
Design and state of development
The A 31 has four lanes, the A 2 has six lanes. The connecting ramp from the A 31 to the A 2 in a westerly direction is two-lane, the remaining ramps are single-lane.
The triangle was laid out as a left-handed trumpet .
Due to the high volume of traffic and partly changed traffic flows, the State Office for Road Construction NRW is planning to convert the triangle; the renovation is to begin at the end of 2021 and be completed in 2024. A preliminary draft is currently available for approval from the state or federal transport ministries. Once the approval has been granted, the planning approval follows.
Traffic volume
The triangle is used by around 145,000 vehicles every day.
