The Red Mountain Freeway alignment is adjacent to and crosses the Salt River within the Superfund site. Six alignments through the Superfund site were evaluated thoroughly. The two most critical constraints prevented location of the alignment on either the north or south bank of the river. These constraints were the hazardous wastes in the landfills on the south side of the river and the Indian community to the north. As a result, the freeway alignment is located on structure in the Salt River. The magnitude of the required twin bridge structures caused significant complications in obtaining a Section 404 permit from the U.S. Army Corps of Engineers. Such a river crossing within an EPA Superfund site is a unique situation. It took 4 years of negotiations with EPA to reach agreement on conditions under which the Arizona Department of Transportation (ADOT) would be allowed to remove landfills on property acquired for the freeway. In March 1992, a one-of-a-kind "agreement and covenant not to sue", which sets forth ADOT's cleanup responsibilities and relieves ADOT from any future liabilities for Superfund cleanup costs, was executed between EPA and ADOT. The cleanup is expected to be completed by January 1, 1996. Two phases of cleanup work are required. The first phase--to clear for freeway construction--was completed in 1993, and the second--to clear an additional area for river channelization--will be performed in 1995.
