Transportation from STL to Columbia?

Hey guys so I live over in the Illinois suburbs of Saint Louis, but I have family in Columbia. You guys have a great town but TBH I don't visit often, for one reason - FUCKING INTERSTATE 70. The drive from Wentzville to Columbia is one of the most stressful experiences for me. Congested with semi trucks, impossible to pass anyone, and there's usually at least one close call per trip.

Are there any good (private) transportation services that go from Saint Louis to Columbia, so that I can visit family without the I-70 shitshow?
