springfield mo to tampa florida

Ditto Odessa GRandma route except we get off I-10 at exit 225 and head south on US19 to US98. East on US98 to Suncoast Parkway (toll). Take the toll to Hwy 54. Go east on Hwy 54 to US41 or I-75 depending on where in Tampa area you're headed. The toll on the Suncoast Parkway is reasonable in my opinion and this route is a lot less stressful than I-75 if you have the time.
