Highway underpass

Portugal has an excellent highway system nowadays. One can get from here to there in no time at all. As a consequence, some areas of the countryside are now striped with highway patterns. This is specially evident in the more densely populated Northwestern region.

The photo below shows a highway underpass we crossed during a country road hike this Spring. It is convenient to drive on it, but quite a nuisance to hike under it. By the way, that's my family over there: daughter, wife and son (on my wife's back).
