GREEN BAY, WI (WTAQ-WLUK) — A Green Bay hospital has reached a major milestone in its renovation and expansion project.
Demolition is now underway on HSHS St. Mary’s Hospital Medical Center’s North Building to make way for the future site of new six-story state-of-the-art patient tower.
The North Building is separate from the main hospital building and has been a part of the St. Mary’s campus since 1958. In recent years, it was used for a range of clinic and administrative needs.
The new patient tower will significantly expand the hospital’s capacity to care for the community, with more than 100 new patient rooms for medical/surgical and intensive care. Most notably, capacity for intensive care patients at St. Mary’s will more than quadruple, growing from eight beds to 36. The tower will also include two new cardiovascular operating rooms and a cardiac procedural room.
For the past several months, contractors have been dismantling the inside of the North Building piece by piece, to prepare the structure for demolition.
Every step of the demolition and subsequent construction has been meticulously designed to ensure patient care is not interrupted and all services in the main hospital remain fully operational.
Work is also being done to revitalize the larger hospital campus, including the creation of a new main entrance, added parking and enhanced security features. New kitchen and dining are also part of the remodeling plans.
HSHS is repurposing and recycling construction materials, medical equipment and furnishings from the now-vacant North Building. The items have been donated to organizations like Hospital Sisters Mission Outreach— which distributes medical supplies to communities in need around the world— and the Greater Green Bay Habitat for Humanity— which supports local housing initiatives.
Groundbreaking on the new patient tower is expected to take place in late summer/early fall this year.
The entire St. Mary’s revitalization project is anticipated for completion in 2028.
The work being done at St. Mary’s is part of HSHS’ historic $270 million investment to revitalize both of its Green Bay hospitals, with the larger portion being allocated to St. Mary’s. Plans are still in progress for renovations to be done at St. Vincent Hospital and will be shared when more information becomes available.
