Route 1 bridges

There is only one major road in Iceland - Route 1.  It was only completed in the 1990's and there are still some dirt or gravel sections in the east. One complication are the bridges which are one lane only and priority is to the person who arrives first!  We're hesitant to approach at speed when we can't see over the bridge hump or the bridge is over 1/4 mile long!  The usual victims are foreigners like the latest crash with a Chinese driver head first into a Japanese driven car!
