The City of Akron, Ohio, will take on what it describes as the city’s largest construction project ever — a three-story high, mile-long tunnel that will be bored 160 feet underneath its downtown area.The four-year-long, $190 million project is part of an EPA mandate to help manage sewer overflows from torrential rainfall. Before the project kicks off, however, it will take one year to construct the massive boring machine to be used for the tunneling project.Once completed, the tunnel will hold more than 25 million gallons of stormwater until it can be treated and released safely into local streams.Las Vegas
