The A10 motorway (Dutch: Rijksweg 10) is a motorway in the Netherlands. This motorway is the ring road around the city of Amsterdam. It has a length of 32 km. Five other motorways connect to the A10: motorway A8 at interchange Coenplein (north), motorway A5 at interchange Coenplein (south), A4 at interchange De Nieuwe Meer, A2 at interchange Amstel, and A1 at interchange Watergraafsmeer. Part of the A10 is the Coentunnel, crossing the Noordzeekanaal ("North Sea Canal"). This twin tube tunnel is notorious for traffic jams for decades, reason why another two tubes have been built. These new tubes opened on 13 May 2013 and the old tubes were closed for extensive renovation. On 21 July 2014 the old tubes were reopened after completing the renovations and all four tubes became be available for traffic.
The city of Amsterdam has a network of numbered stadsroutes (city routes). These routes are indicated with an "s" prefix followed by a three digit number starting at 100. Since these s-routes are connected to the A10 motorway and each s-route only crosses the motorway once, these numbers can be considered as the first exit numbers on Dutch motorways. Recently, regular exit numbering has been implemented based on the numbers of the s-routes. For example, the junction leading towards the s106 used to be exit number s106 and is now numbered as exit 6.
