The A6 motorway, of which the largest part is located in the province of Flevoland, is the shortest route between the city of Amsterdam and most parts of the northern provinces of Friesland and Groningen.
Hollandsebrug
In April 2007, it was announced that the bridge Hollandsebrug, the bridge between intersection Muiderberg and the city of Almere, did not meet the quality and safety standards. The Dutch research organization TNO found out that heavy trucks could cause holes to appear in the road surface. Therefore, as of April 27 of that year, heavy traffic was not allowed to cross the bridge in either direction, and was forced to use the A1 and A27 motorways instead, a detour of about 20 kilometers.
