On the A1 at Winterthur is currently being built brisk. A reader of the commuter newspaper "20 minutes", the Winterthur is regularly on the motorway section between the Töss and the upper on-the-go, is surprised: "There are countless, massive beams above the roadway will be created," he says. Which was to him a mystery. "This is overkill, a waste of money."
The bars are called in the technical language signal portals. In the said section of the Federal office for roads (Astra) made up a total of 19 portals, as it says on request.
they span both of the carriageways and roadside strip and need to carry up to seven-Meter-high panels with a weight of one ton. "The cost for that is exclusive Signals to around six million Swiss francs," says spokesman Tobias Bolli.

the purpose of the signal portals – where cameras, traffic detectors, and display boards will be mounted – is a better use of the existing infrastructure. "To be able to transport better to control, it needs a complete Overview of the roadway," said Bolli.
In the twisty sections around Winterthur and more portals are therefore needed than in a straight line.
With the portals it is possible to identify dynamically to the traffic impact and hazards at an early stage. "At the push of a button can be driven point and their traffic impact by-step speed adjustments to minimize it."

So they wanted to take advantage of the remaining capacity of the infrastructure in a better and more flexible, and so traffic will prevent traffic jams. The signs were prepared in accordance with the prescribed standards.
Similar projects are also planned for Zurich on the A3 in the direction of Pfäffikon SZ. You are to be implemented within the next two years.
