Novice question: I noticed on all the highway construction around me that the I-beams get 'smaller' where they mount to base/beginning of an overpass or even an intermediate supporting structure. For instance, the vast majority of the I-beam appears to be 8' tall, but at the termination points it might only be 4' tall.
Why not just make the same size all the way?
