The Knooppunt Bodegraven is a motorway triangle in the Dutch province of South Holland in the south of the city of Bodegraven . It connects Rijksweg 11 (N11: Leiden - Alphen aan den Rijn - Bodegraven) with Rijksweg 12 (A12: Oberhausen - Arnhem - Utrecht - The Hague ). Until 2015, today's junction was exit 12a of the A12.

The knot is named after the small town of Bodegraven , which lies north of the cross.

history

The Knooppunt Bodegraven was opened to traffic as a junction at the same time as the section of the A12 between Reeuwijk and Woerden on November 25, 1939 . At that time it was one of the first interchanges to be realized as motorway forks in the Netherlands. In 1939, however, the A12 was expanded to three lanes before it was expanded to four lanes in 1940. The N11 does not yet exist, so the exit ended at Goudseweg and the connecting ramp towards Utrecht ran over the A12. In 1965 the first section of the N11 was opened and connected to the junction, which at that time was already free of intersections.

In 1980, the A12 was expanded to six lanes in the area of ​​today's motorway triangle. For this purpose, a new lane was laid south of the old A12 and the connecting lane from Leiden to Utrecht, the junction at that time, was brought under the A12. At the same time, the Bodegraven rest stop was built immediately behind the exit. On May 18, 2004, the four-lane N11 was opened to traffic at Bodegraven. From then on, the junction was de facto a Knooppunt according to Dutch regulations, but was still referred to as a junction.

Between 2010 and 2012 the A12 was extended to eight lanes on the existing route, but the junction at that time was not adapted. In October 2015 the junction was officially renamed to a Knooppunt and the number 12a of the exit was dropped.

Design

The motorway triangle is built in the form of a motorway fork. The A12 has eight lanes near the junction, the N11 has four lanes. The connecting ramp from Utrecht towards Leiden is two-lane. On it there is a branch to the Bodegraven rest area, which is immediately behind the triangle, and a branch to the Bodegraven exit. The connecting carriageway from Leiden to Utrecht is also two-lane . It runs in a wide arc under the A12 and is reduced to one lane shortly before the junction.

In the triangle it is not possible to drive from Leiden on the A12 towards Gouda and vice versa. For this you have to balance on the Goudseweg which connects the Bodegraven exit of the N11 with the Reeuwijk exit of the A12.
