A9 motorway (Netherlands)
The A9 motorway is a motorway in the Netherlands. The motorway starts off by going from the A1 at Diemen (junction Diemen) to the A2 at junction 'Holendrecht' (on the 'Gaasperdammerweg'). Overview Here one drives approximately two kilometers south by means of the combined A9/A2 before the A9 heads off to the west again towards Amstelveen, junction 'Badhoevedorp' (A4), junction 'Raasdorp' (A5), junction 'Rottepolderplein' (A200) and on to junction 'Velsen' (A22). Hereafter, the A9 goes further northward by means of the Wijkertunnel under the North Sea Canal, junction 'Beverwijk' (A22) to Alkmaar. At this point, the A9 motorway becomes the N9 highway and proceeds until De Kooy (at Den Helder). In 1996, the Wijkertunnel was opened and integrated into the A9. The original route of the A9 ran through the Velsertunnel where there is also a connection with the A208. This part still exists but this portion of motorway has been re-numbered to A22. The part between A1 and A2 is four lanes; between A2 and Rottepolderplein it is six lanes. Hereafter the way is mainly four lanes, with short pieces in the area of the Wijkertunnel that are six lanes. With regard to the Gaasperdammerweg, it is noted in
