LifeBridge Health, which also owns Sinai Hospital of Baltimore, is spending $29.5 million, including $5 million from the state, to replace the affiliated children's hospital after 53 years in the same building. Wiley said the hospital is reacting to demand after noticing several years ago that it didn't always have enough, or appropriate, rooms to place patients. Once patients move into the new building on March 19, the old facility will be renovated and converted into a place for outpatient procedures.
