This interchange study included new, fully directional interchanges with collector-distributor roads at the Airport Midfield Terminal and at Six Points Road and incorporated widening and relocation of the existing Six Points Road north to US 40, as well as a new connector road south to SR 67.  The study also included the relocation, widening, and lowering of I-70 from the Six Points Road interchange to I-465, and the modification of the I-70 interchange with I-465.  The Environmental Assessment included potential impacts to threatened and endangered species, wetlands , and “waters of the US,” historic properties, and relocations. To address impacts to the federally threatened Indiana bat, American Structurepoint  prepared a Habitat Conservation Plan, the first such report in Indiana.  American Structurepoint also coordinated with IDNR, IDEM, USFWS, and the Corps of Engineers to relocate a 1-mile portion of White Lick Creek.  Also coordinated with IDNR regarding potential historic and prehistoric archaeological resources and historic properties.

The following are sustainable aspects of this project: 

• Strategic rerouting of two miles of the East Fork of White Lick Creek, North Creek, Luck Creek, and Middle Creek reduced the number of new bridges required for the proposed Indianapolis Airport and Six Points Road.
• Increased erosion control through innovative reuse of on-site forest materials
• Several loops of the original creek were retained as oxbows to provide enhanced aquatic and waterfowl habitat.
• Restored over 500 acres of local habitat
• Temporary streambed crossings were carefully configured and stream depth controlled with weirs to ensure natural hydraulics during construction, and construction-phase erosion control was carefully designed.
