There is a thing called road diet, take 4 lanes (2 each way), reduce it to 2 lane and add turn lanes and bike lane.

Car traffic hopefully slows and makes things safer for pedestrians crossing the road and much safer for cyclist.

The wikipedia only lists a few examples where it has been implemented:
