he Alsace is only across the River Rhine (around 30 minutes by car).
If it across river directly it gives me the next calculation:
-With average speed limitation of 40/60 kph at bridges it means that bridge is at least 20 km wide.
Correct me if I wrong but the longest river bridge in Europe is bridge over river in Lisbon . Only 18 km. So your bridge is 2 km wider at least.
Or you have to swim each time when going to France!
