Interstates nearing completion: State engineers say they will finish widening Interstate 85 through Cabarrus County in April. The last leg of I-485 and the I-85/I-485 interchange should open in December. The state’s first “turbine” interchange is being built at a $50 million savings compared to traditional designs, according to University City Partners. A computer-generated simulation on YouTube lets viewers “fly” over the spiraling 19-bridge interchange or ride with traffic down one of its through lanes.
