Barricades went up Monday in downtown Greencastle, closing off South Vine Street to through traffic between Washington and Seminary streets to facilitate the third and final streetscape project of the city's Stellar Communities grant. New pavement, sidewalks and improved drainage are all part of the construction project being undertaken by Schutt-Lookabill Co., Indianapolis. Construction deadline is Oct. 1 on the project. Cross streets Walnut and Poplar remain open at present as construction is due to begin in the alley south of the Post Office.
