A7 motorway (Netherlands)
Location of the A7 motorway
The A7 motorway is a motorway in the Netherlands connecting Zaandam, via the Afsluitdijk, Sneek and Groningen to the German border near Bad Nieuweschans. The entire road is part of the European route E22, with exception of the first kilometre, between the terminus in Zaandam and the interchange Zaandam. With a length of 236 km it is the longest motorway in the Netherlands.
The motorway A7 is interrupted twice:
- Around Sneek, the road is 'demoted' to a highway for several kilometres, and included some at-grade intersections, the at-grade intersections were replaced with grade separated intersections in 2008–2010, however, it isn't a motorway.
- Also around the city of Groningen it is demoted over a distance of several kilometres, mainly for the at-grade intersection with motorway A28, and for the road's small alignment through the city in general.
Both of the abovementioned sections are denoted as 'N7', to distinguish those parts from the motorway, for which the 'A' designation is used in the Netherlands. The A7 together with the N7 is called the Rijksweg 7.
Speed limit experiment
From March 2011, on a section of the A7 motorway, motorists were allowed to drive at 130 km/h, opposed to the then national speed limit of 120 km/h. This was a government test to investigate if driving at these higher speeds have an effect on the environment and safety. The test resulted positively, and the national speed limit was raised to 130 km/h in October 2012.
The A7 runs across a historic part of Dutch engineering, the Afsluitdijk. This dam was originally created to protect the country's long interior coastline from floods by creating a large freshwater lake. The road over the Afsluitdijk was previously a 2-lane N road, but is now a proper motorway; the upgrade to motorway was achieved by utilising the dike's unused railway reservation for the second carriageway. Its midpoint is near the village of Breezanddijk. The former State Secretary for Infrastructure and the Environment, Joop Atsma, issued a statement detailing the factors influencing the decision to build a new naviduct on the Afsluitdijk section of the A7 at Kornwerderzand. A naviduct and new locks was costed at €200–450 million, depending on the size of locks and size of highway. A naviduct would give waiting time annualised benefits €13 million to road traffic, based on the existing bridge opening 7,000 times a year. Cost–benefit analysis of all potential solutions were considered, and a naviduct could be built to replace the locks when they reach the end of their useful life in 2050.
