Most Transport Agencies are basically just high way construction offices. That is basically why they were created, or at least when state level DoT became massive, to construct highway.

They can build an mind glowingly insane 7 level loop clover with integrated rocket launcher and helipad but they couldn't design a safe and efficient pedestrian crossing if it smacked them in the face.

They are still planning new highways right threw actual real existing cities as if they were Robert Moses. Its literal insanity.
