Why Build a Regional Tunnel System?

The new regional tunnel system will consist of three major tunnel projects, all approximately 150+ feet deep, which will capture wet weather combined sewer overflows and move them to the plant for treatment.

At ALCOSAN, we know construction delays and closures can impact your daily travels. We hope to mitigate some of the frustration by providing timely closure or delay notices on this page, as well as through our social channels.

Riverfront Trail Closures

As ALCOSAN continues work towards construction of the new Ohio River Tunnel, we have to do core borings along the tunnel route. Because of this work, we will have to temporarily close portions of the riverfront trail, but detour and closure signs will be prominently displayed.

The schedule and areas of the closures are:

  • 10/19-11/2 – Trail closure between Westhall and Doerr Streets
  • 11/2-11/17 – Trail closure between Doerr St. and Preble Ave. (side street)
  • 12/1-12/17 – Trail closure between Island Ave. and N. Franklin St.
  • 12/17-12/31 – Trail closure between N. Franklin St. and Kroll Dr.
