Connecticut Children’s — which began operating in 1996 as the successor to Newington Children’s Hospital — is planning a $280-million expansion anchored by a new 190,000-square-foot, eight-story patient tower on its Washington Street campus. The ambitious project will create upwards of 500 new jobs — including temporary construction positions as well as the hiring of about 25 new physicians and more than 130 nurses. Connecticut Children’s earlier this month outlined its expansion plans in a Certificate of Need (CON) application filed with the Office of Health Strategy, which must ultimately approve the project. The hope is construction could begin by April 2023, and the tower completed by the end of 2025. Connecticut Children’s said it plans to pay for the $280 million project by utilizing a number of different funding opportunities including philanthropy and structured loans. It didn’t provide further details.
