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 the original plans that this road would not become a motorway. The plan was to build a local link-road for the occupants of the Bijlmermeer. The section between A2/A9 and A1/A6 was never built, although this would have formed a natural connection between A9 and A6. Because of this, the Gaasperdammerweg has developed into an overflowing connection between A2 and A1.
Discussions on extending the A9 in a straight line to the A6 are still going on. Because this part of the route would pass by the Naardermeer, environmentalists oppose this plan.
