UTRECHT, 11 August 2008 – Strukton and TBI Infra have devised an alternative solution for the A6 and A9 motorway connection between Amsterdam and Almere. The solution involves the construction of a tunnel that uses existing foreign technology to entirely remove and filter fine particles, without ventilator towers creating an eyesore or polluting the landscape.

The plan involves creating a closed outer ring road around Amsterdam via a tunnel between the Holendrecht and Muiderberg junctions: the ‘missing link’ between the A9 and A6 motorways in the direction of Almere. The tunnel consists of two tunnel sections, each comprising three layers, with a centre layer for three lanes. The tunnel passes the Naardermeer, some distance from the current A1 motorway. What’s more, since it lies underground, it will be invisible, inaudible and odourless. Only after the Muiderberg junction in the direction of Almere will the tunnel emerge from beneath the ground. Its design incorporates the technical and traffic-related expertise of the Haskoning engineering agency.
