The project included improvement of the I-65/I-70 corridor through Indianapolis, Indiana. Reconfiguration of the current interstate corridor and associated bridges and culverts are the primary focus of this project.
ASC Group completed a historic properties survey for the Area of Potential Effect. Efforts to identify historic properties in the APE included a check of records available via the State Historic Architectural and Archaeological Research Database (SHAARD), field work, and communication with consulting parties. The results of the field surveys were reported in a Historic Property Report (HPR). There are many notable historic properties within the APE, including two National Historic Landmarks (NHL), 27 resources individually listed on the National Register of Historic Places (NRHP), ten NRHP-listed historic districts within the APE including Old Northside, Massachusetts Avenue, and Chatham Arch historic neighborhoods. All NRHP-listed resources are automatically included in the Indiana Register of Historic Sites and Structures (IRHSS); in addition, there are two individual resources and one district listed in the IRHSS. In addition, there are two resources previously identified as NRHP-eligible. ASC identified an additional seven individual resources and two districts that are recommended eligible.
