An artificial river flows through the heart of the American Tobacco Historic District. The river is more than a quarter-mile long and holds 440,000 gallons of water.
Officials said it took crews more than five days to fill up the river. The Durham Fire Department was also called to assist with the water.
Artists were called in to paint and chisel the concrete to make it look old to match the age of the building. Workers are also putting the finishing touches on an amphitheatre near the river.
Capitol Broadcasting Co., which owns WRAL, is developing the American Tobacco project.
