As of Thursday evening, the parking deck in downtown Cumming is closed forever.The 246-space deck at East Main and Mason streets, which opened in 1994, will be demolished in mid-January to make way for a new Forsyth County courthouse.The courthouse and jail projects were approved as part of a November 2011 referendum to extend the special purpose local option sales tax, known as SPLOST VII. The projects, including two new parking decks, are estimated to cost about $100 million, or nearly half of the anticipated revenue from the six-year tax collection.The demolition of the parking deck and the buildings across from the current courthouse will be the first noticeable change in the appearance of the Cumming square as the ground is readied for the new buildings.People visiting the current courthouse will need to park at the lot at the southwest corner of Maple Street and Castleberry Road during this phase of construction.
