Phase One Cultural Resource Survey Of Proposed Trunk Highway 60 169 Bridge Alterations For Us Army Corps Of Engineers Flood Control Project In Mankato North Mankato And Le Hillier In Blue Earth And Nicollet Counties Minnesota PDF Download

A Phase 1 cultural resource survey of two proposed trunk highway bridge crossing modification projects in association with the Mankato Flood Control Project were conducted during August and October 1981. Study areas include the one-quarter mile relocation of the T.H. 60-Main STreet bridge and approaches over the Minnesota River in Mankato and North Mankato and the three-quarter mile long minor realignment of the T.H. 169 bridges over the Blue Earth River and approaches in West Mankato and Le Hillier. A literature search, records review, and an archeological survey, including surface reconnaissance and shovel test excavation were conducted. The literature search and survey resulted in the location of one archaeological site, 21 BE 63, within the study area. This site was located within the proposed right-of-way acquisition zone but is not directly affected by proposed highway approach construction. Preservation of this potentially eligible prehistoric stone tool manufacturing site within the proposed right-of-way is advised. The original Mankato Townsite was also identified on the basis of literature research as a potentially sensitive area although it was inaccessible to subsurface testing due to modern urban development. No other archaeological resources were defined within the project study area, and no further cultural resource surveys were recommended.
