Practically every major city with an Interstate has what is called a bypass, typically at least two. These look like a ring around the city in most cases and are (typically) the even numbered 3 digit interstates. The bypasses are almost always faster to take if you're just moving on through to the other edge of town. These would have been totally sufficient in almost all cases w/o plowing the Interstate itself through/near the downtown cores in addition to the bypasses.
