What will the reconstructed highway look like?
The reconstructed highway will be an urban interstate with 12-foot lanes in a minimum 216-foot right-of-way, and a 30-foot paved median with a concrete barrier. Inside shoulders will be 14 feet wide; outside shoulders will be 10 feet. Additionally, right-of way needs may expand in areas of cut and fill and would be larger at interchange areas. Allowable mainline grades will remain no greater than three percent. Full control of access will continue to be exercised. Interchanges will also be reconfigured to improve both safety and capacity for travelers entering and exiting I-465, as well as those traveling across and through the I-465 corridor. The Airport Expressway interchange will retain its current geometrics through 2008, pending the reconstruction and relocation of the new airport terminal. Our team is working closely with the airport to facilitate their planning and to ensure close coordination as the project moves forward. By maintaining the existing ramp geometry and adding an
