There is a ton of construction from south of Lexington to Charlotte. I-85 is being relocated from a two lane bridge pair to a new four lane bridge pair over the Yadkin River. Currently, both directions of travel are on the new northbound bridge while the southbound bridge is being built. Also, I-85 is being widened from four lanes to eight from NC-87 south of Concord to I-485 in Charlotte. During the day, there can be tremendous traffic backups from either of these construction projects. Taking I-40 from Greensboro to Statesville and I-77 south to Charlotte may be faster. However, if you are into road construction, these widening projects have all sorts of goodies. There are temporary access ramps from freeway bridges into construction zones for construction traffic only. The new I-85 Yadkin Bridge is causing US 29/70/NC 150 to be rerouted off of I-85 earlier and a new road is being built to the old US 29/70/NC 150 bridge, which is being refurbished as well.
