They didn't widen it; they just had to shore up the sloping earth bits on each side of the Conestoga Parkway a bit. The "sidewalks" on the deck sides are exactly where they were before the project started; it's not like they built wing extensions or something on the sides.
I misspoke before; it will have two lanes in each direction still; my bad.
