The Three Rivers Protection & Overflow Reduction Tunnel (3RPORT)
On April 6, 2017, Lane was awarded a $188 million contract for the Three Rivers Protection & Overflow Reduction Tunnel (3RPORT) project. The project is a combined sewer overflow (CSO) tunnel located in Fort Wayne. It includes a deep rock tunnel, drop shafts, and consolidation sewers to collect and convey combined sewer overflow from eight locations along the St. Mary and Maumee Rivers. Once completed, the CSO tunnel system will reduce 90% of combined sewage overflows into the rivers, which occur during large rain storms.
