US 30 from IL-136 to IL-40


US Route 30 (also known as Lincoln Highway) is a major east-west highway facility between northwestern Illinois and eastern Iowa.  Within the project study area, US 30 passes through the City of Morrison and is in close proximity to the City of Fulton, the City of Rock Falls, the City of Sterling, and the City of Lyndon.  US 30 connects to Clinton, Iowa, just west of the study area.  Currently, US 30 is a two-lane, undivided highway within the project limits.

Project Cost:
$350 Million


A corridor feasibility study was conducted for construction of a four-lane improvement to US 30 within a study area that extends along existing US Route 30, approximately 18 miles from the city limits of the City of Fulton near the Mississippi River, to Interstate Route 88 west of Rock Falls.  This multi-lane expressway facility would provide increased access to Interstate Route 88 from adjacent communities and eliminate through truck traffic from the City of Morrison.  


Kaskaskia Engineering Group, LLC (KEG) provided GIS services for the entire project.  The primary duties included mapping environmental resources, developing figures to support the analysis of an Environmental Impact Statement (EIS), and developing mapping products for the Context Sensitive Solutions (CSS) process, including all Community Advisory Group (CAG) and Project Study Group (PSG) meetings.  In addition, KEG incorporated all natural, cultural, and socioeconomic information into a GIS database; interpreted aerial photography for the preliminary identification of terrestrial cover types and wetlands; compared aerial photography with NWI mapping for wetland discrepancies; and assisted in quantifying all environmental impacts impacted by the proposed transportation corridors.  The resulting GIS maps assisted in investigating discrepancies, including biological, socioeconomic, historic, and archaeological research, and continuing field efforts.

Based on the outcome of the Feasibility Study, funding was provided for preparation of an Environmental Impact Statement (EIS) and Phase I Design Report for this project. KEG is assisting the design team of Volkert, Inc. and Howard R. Green Company with preparation of the EIS. The EIS process includes intensive field investigations for threatened and endangered species, wetlands, and historic resources.  In addition, KEG is providing GIS services for mapping resources within the corridor, assessing the impacts of improvement alternatives, and providing exhibits to support the public involvement activities, utilizing the Illinois Department of Transportation’s CSS process. Approval of the EIS is expected in late 2015.
