Motorway interruptions

The motorway A7 is interrupted twice: *Around Sneek, the road is demoted to a highway for several kilometers, and includes 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 kilometers, 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 , opposed to the then national speed limit of . 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 in October 2012.

Afsluitdijk

The A7 runs across a historic part of Dutch engineering, the

. 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

. 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

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 Cost–benefit analysis (CBA), sometimes also called benefit–cost analysis, is a systematic approach to estimating the strengths and weaknesses of alternatives. It is used to determine options which provide the best approach to achieving benefits ...

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.
