South City Parkway is planned to eventually be extended to Kaliste Saloom Road. It will intersect Kaliste Saloom between S. Meyers Drive & Peck Boulevard. The draft pictured below from LCG Public Works Department also shows that it is expected to go beyond Kaliste Saloom and eventually connect to other road ways. This extension will ease some of that pain of driving down Ambassador on a busy weekend or day.
You can find the planned extension on Google Maps too. https://maps.google.com/maps?ll=30.1582286,-92.0719786&z=17&output=classic&dg=ntvb
Please keep in mind, this is a draft and drafts from my knowledge are not set in stone.
