Can Interstate 55 take me to San Antonio Texas?

It can't. However, I-55 intersects with the 10 in St John the Baptist, LA. Since there are more ways to get to San Antonio from I-55, I suggest getting driving directions. But wait...if you live near St Louis, just take I-44 W into Tulsa OK, then take US-75 S into Dallas. Then take I-35E S. I-35E S then takes you to San Antonio.
