> ... 1m of road costs about 10000 euro ... Too little information. If 1m is length, what is the width? where is the road located? If it's a two-way superwide highway in the middle of a big city, sandwiched between a similarly sized winding overpass, and an underpass, and the cost includes the overhead on the city's economy for shutting down that part of the highway for the given duration, we might be having a conversation.

It fits right in the middle for Autobahn, so in this case I assume 2 lanes each way (with a third at the right for emergency stops), controlled access, no major earthworks, and either steel or steel-reinforced concrete center and side barriers. Also including some trees or brush either side to shield noise and, presumably, also side winds. Depending on curves, it would be rated between 120 km/h and ~200 km/h (though anything above 130 km/h seem to be declared as "no limit", deferring to the motorist's judgement).
