Project Corridor IA 100 Project Corridor Limits and Features Extension of IA 100 From Edgewood Road to US 30 Crossing of the Cedar River System Interchange at US 30 Three Local Service Interchanges Two Rural Standard Diamond Interchanges Single Point Urban Diamond Interchange 8 Miles of New Four Lane Freeway Rural and Urban Sections Constraints Morgan Creek and Morgan Creek County Park Iowa Northern Railroad Rock Island Preserve Wetlands and Historic Constraints 3
Project History Linn County Regional Planning Commission identified the route as an integral part of their metro plan in 1969 LCRPC added IA 100 extension from I-380 to Edgewood Road in 1977 Iowa DOT began Location Studies to extend IA 100 to US 30 and circulated a DEIS in 1978 Final EIS approved and circulated in late 1980 Spring 1983 IA 100 Construction from I-380 to Edgewood Road began Funding constraints delay the rest of the corridor Reevaluation of 1980 FEIS determined in 1998 and the project corridor added back into the DOT s transportation plan FHWA determined a Supplemental EIS should be prepared in 2000 Supplemental DEIS with Preferred Alternative released for circulation in mid 2001 4
Project History cont. Subsequent Corridor Alternative Evaluations Late 2001 to Avoid Rock Island Preserve Late 2002 to Avoid Byssus Skipper Habitat Fall 2004 to Avoid/Minimize Impacts to Blandings and Ornate Box Turtle Habitat Late 2005 Linn County Conservation Board Alternatives to Avoid Rock Island Preserve FHWA recognizes the Rock Island Preserve as a 4(f) Resource Alternatives Evaluation continues through mid 2007 SEIS Finalized and Signed in 2007 Preliminary Design started but stopped at 30% plans in 2009 Preliminary and Final Design restarted in 2011. 5
