Work will begin Saturday morning to improve the appearance of the City of Vincennes' three gateway entrance signs. The "Welcome to Vincennes" signs are located at the Hart Street & Kimmel Road intersection; between McDonald's and Pizza Hut on Hart Street, and on North 6th Street. City officials say the appearance of the signs will be improved through the use of shrubbery, ornamental grasses and trees. Part of the work is being paid for through a one-thousand dollar grant from the Vincennes/Knox County Convention and Visitors Bureau. Volunteer assistance will be provided by Pepsi of Vincennes.
