Jefferson County, In. — The Indiana Department of Transportation will close State Road 250 next Tuesday, August 7, for up to 90 days between U.S. 421 and State Road 62 in Monroe Township of Jefferson County. Specialty crews have been contracted to stabilize an eroding embankment 10.7 miles west of the Switzerland County line on State Road 250 just north of the S.R. 62 “Y”.A state highway detour routes motorists around the site via U.S. 421 and State Road 62.Geostablization International, INDOT’s slide mitigation contractor, will embed 20-foot-long steel shafts into the slide area which measures 900 feet side-to-side and eight to 11 feet in height. Ends of these “soil nails” will be fitted with a wire mesh, then overcoated with shotcrete to form a stabilizing wall. The $1 million project also calls for pavement replacement and installation of curbs and gutters.State Road 250 at the slide site has a traffic count of 780 vehicles per day.
