"Suddenly going to 2 lanes from 4 is going to cause even worse congestion."
Not necessarily. Without knowing the scope of the surrounding area regarding roadways how it will change can't be predicted. However, there is plenty of data that how congested traffic doesn't have as much to do with how many lanes there are.
A lot of place expand to 4 lanes to compensate for more traffic, but traffic rarely improves because those 4 lanes will eventually merge to 3 or 2 and heavy traffic being forced to merge slows down traffic ever more.
So it's possible, even likely, you won't see much of a difference.
