Also, the interstate network was built to run through the existing centers of cities instead of around the edges, unlike most of the motorway/autobahn class roads in Europe. > So effectively you have high-speed roads with appropriate access > restrictions (preventing people from entering them) running through the > cities and once a road enters an area where people are allowed, there's a > speed limit sign? America is kind of a strange place when it comes to mixing high-speed automobiles and non-motorized transport. I grew up not too far from a city street with a 55 MPH (90 km/h) limit and sidewalks/pavements on both sides, yet currently live blocks from a motorway with signs banning bicycles and pedestrians, even though a heavily used access to a hike/bike trail is located at one of the entrance ramps. -- David J.
