The discovery of indigenous peoples’ artifacts will not significantly delay the start of construction of the Constitution Boulevard extension planned for next month, according to Mayor Mark Lauretti. Lauretti confirmed the discovery of the artifacts on what is known as the Churma property — the site at 55 Blacks Hill Road which was recently condemned by the city. “Archaeologists are dealing with this now,” Lauretti said. “It is causing a little bit of a delay, but I still believe we will be starting next month. The Constitution Boulevard work — on the drawing board for some three decades — is expected to be completed within a year from groundbreaking, Ron Nault of DeCarlo and Doll Architects and Engineers told residents of Cotts Street and Blacks Hill Road, all impacted by the extension of the road into the city-owned Mas property, during an informational meeting Wednesday.
