I think you will want to specifically check out pg. 6
of this document....depending on where you're moving to, you might contact all 3 campuses to see your best shot at eligibility...unless you're extremely adverse to driving, none of them is a horrendous drive from most areas in St. Louis: http://www.stlcc.edu/nursing/2003-2004%20Handbook.pdf
The community college is extremely affordable and has a good reputation in the community. Other options are: Jefferson Community College, St. Charles Community College, and perhaps Barnes Jewish Nursing Program: Barnes-Jewish College of Nursing and Allied Health
but I don't know that any of them offer a bridge program -- they're just other local selections depending on where you will be living, plus I believe I have read that Barnes is eliminating their ASN program in favor of strictly the BSN degree.
