Specially Designed Tunnel Boring Machine Uses Innovative Microtunneling Process to Complete First of Three Tunnels in Transformative Clean Water Infrastructure Project.  $32 Million North Interceptor Sewer Improvement Project Prepares City for Development While Protecting the Hudson River Watershed.

The City of Newburgh today announces the successful completion of the first of three underground tunnels planned for the City’s $32 million North Interceptor Sewer Improvement Project. This phase of the project is being completed by a specially designed tunnel boring machine (TBM) capable of “microtunneling” – an innovative, remote-operated trenchless construction method that allows for simultaneous excavation and pipe laying with minimal disruption to residents. Over a period of 35 days, the TBM broke through 487 feet of solid rock, traveling a path along Colden Street, between First Street and Second Street to complete the first tunnel.
