Four partners in a project that could build a Missouri River port to one of two sites near Jefferson City are moving closer to formally applying for a port authority with the Missouri Department of Transportation. An economic impact report completed in mid-June for the Jefferson City Area Chamber of Commerce, the Cole County Commission, the Callaway County Commission and Jefferson City says either proposal could create 4,385 jobs throughout the 25-year life of the port - or about 175 jobs per year.
