Alton Memorial Hospital and BJC Medical Group are expanding their presence in Madison County with a new medical office building that will soon be under construction in Bethalto. The building will replace the Family Physicians of Bethalto office and will be located on the south side of Route 140, just east of its current location. At nearly 9,000 square feet, the new structure will be four times the size of the current office. It will be able to accommodate five providers; the current space has room for only two.
