The purpose of the project is to: 1) accommodate planned growth, 2) redesign the interchange to be compatible with planned City and County improvements to the local and regional arterial system south of I-8, 3) improve drainage at the interchange, and 4) incorporate improvements to safety. Comments on the draft environmental document are due no later than March 8, 2004.
