Booming growth of the Charlotte area made it necessary for expansions and improvements on the highway systems. One of the newest improvements is the widening of Interstate 77. This improvement gives drivers of the Charlotte and Lake Norman area the choice of using express lanes, general purpose lanes or a combination of both. The Express lanes will run adjacent to the existing general-purpose lanes and will be 26 miles of dedicated toll lanes from I-77/ I-277 in Charlotte to Exit 36 in Mooresville.
