I want to know the answer to the following question:
What would the use of a new carriageway do in Alsace?
All the background I'm provided with is that "At present, plans are being considered for building a new dual carriageway west of Strasbourg, which would reduce the buildup of traffic in that area by picking up north and southbound vehicles and getting rid of the buildup outside Strasbourg.". Is that enough to answer the question?
Answer: yes
