Fort Wayne City Council approves tunnel project contract.
A $187.7 million construction contract has been approved to build the Three Rivers Overflow Reduction and Protection Tunnel in northeastern Indiana.
The project is part of a long-term plan to reduce the average number of combined sewer overflows in Fort Wayne from 76 to four.
Construction is expected to take 4½ years.
Healy Joint Venture — the lowest of five bidders, the Journal Gazette (http://bit.ly/2pNIu7c) reported.
This will be the joint venture’s fourth combined sewer overflow project.
Tunnel boring machines will run 24 hours a day and five or six days a week, said Mike Kiester, city Utilities Engineering manager.
"We’re proposing to go almost 25,000 feet, or five miles, starting at our east Dwenger site next to our water pollution control plant, basically following the Maumee River and then the St. Marys River down to the northern end of Foster Park," Kiester said.
Work began in 2012 on building 27 miles of 18-foot diameter tunnels as part of a $1.6 billion project aimed at reducing the release of raw sewage into Indianapolis’ rivers.
Construction is expected to continue until 2025.
