Motorways help peolpe travel quickly and cover long distance but they cause some problems Nowadays fortunately there are a lot of means of transport. Motorways are the best way to connect different city unless across more countries but like everything have some problems and can caused big or little accident. One of the problems can be the maintenance of the street, the bridges, the overpass and other because if you do not this can be big incident like Genova that recently had an enormous accident in the street that collect the city from other, with maybe 30 death and a lot of injures because the overpass collapse from time to time. Moreover an other important problem is the pollution of the environment but also the destroy of it because if you built a street you demolish mountain, little hill, all flora and vegetation that encircle our. I concur that the best thing to do is control everything and before to built something think to future causes that can have or do because with a little maintenance street, bridge and other survive a lot of time.
