Three men look at street sign

Tom Guzzo, mayor of New Kensington and pictured far right, works with two members of the City of New Kensington's street department to determine placement of one of five signs that comprise Penn State New Kensington's Sustainability Stroll. The interactive tour, along five blocks of Fifth Avenue in the city, links local businesses and organizations to the United Nations' Sustainability Goals and local history via unique QR codes and web links on each sign.
