I-70 Six Points Road Interchange Stream Restoration Project

Client: Federal Highway Administration and Indiana Department of Transportation

Location: Hendricks and Marion Counties, Indiana

Services: Environmental planning and design

In February 2002, the Federal Highway Administration (FHWA) and the Indiana Department of Transportation (INDOT) contracted KCI Technologies, Inc. to provide technical stream restoration services for the I-70/Six-Points Road Interchange Stream Relocation Project. As the single largest stream project in INDOT history, KCI will relocate over 2 miles of the East Fork of White Lick Creek and North Creek. The relocations will require two completely different design approaches due to the types of channels.

The East Fork of White Lick Creek is a wide channel on a low gradient with a watershed that is relatively close to ultimate conditions. The North Creek is a small channel on a medium grade in a watershed that has great potential for development. Its relocation will include a confluence with South Branch and a Tributary to Luck Creek. The future watershed for the relocated North Creek will be heavily developed due to the airport expansion.

The entire I-70/Six-Points Road Interchange project involves the design/build of an $120 million interchange and associated roadway work as part of the new City of Indianapolis “North-South Corridor” which provides access to its new $800 million Mid-Field Passenger Terminal for the Indianapolis International Airport, which is scheduled to open in 2007. INDOT lists the project as a “fast-track” project due to the short window of time available to complete both the designs and construction. In order to meet the June 2005 completion date for the new interchange, the stream relocation project must be completed in 2003, the roadway-grading contract must be completed in 2003, and the actual interchange/roadway construction must be completed in 2004-05. KCI is currently working under this tight schedule and has completed the fluvial geomorphologic assessment, existing conditions H&H analysis and reports, and portions of the phased restoration design. To date, construction has begun on the first project sections.
