IBM Endicott Fill-In Work Underway with Tunnels Preserved

After several months of inactivity, there suddenly is a flurry of activity at the old IBM Endicott manufacturing site.

Five massive abandoned buildings at the Huron Campus that had been used by "Big Blue" for much of the 20th century were demolished by Gorick Construction Company last year.

Large piles of debris containing asbestos were left at the site after the structures were torn down. The material - which remains covered - won't be accepted at the Broome County Landfill until further notice.

Since last summer, the 10-acre site has been dormant. But in recent days, crews have started backfilling operations on the property.

Chris Pelto, who oversees Huron Campus operations for Phoenix Investors, could not be reached to discuss the specific work now underway.

But it's expected that the old construction fencing that's surrounded the perimeter of the site at North Street and McKinley Avenue since late 2024 will be removed as the workers prepare additional space along the sidewalk.

Some greenery also is to be added at the intersection in an effort to make the site a bit more attractive.

Despite the removal of several huge IBM buildings, the network of tunnels that provided underground links to different sections of the complex has been retained.

One of the tunnels - running under North Street - was constructed in 1962 to connect the new IBM employee cafeteria to manufacturing and office buildings.

The former cafeteria became The McKinley - a popular event venue that was closed about three years ago.

No redevelopment plans have been announced for the recently-cleared section of the Huron campus.
