News About Town: Watch out for falling speed limits. Several roads in Matthews will have reduced speeds: Sam Newell, Charles Street, Sardis Road, and Weddington Road. Sam Newell at Crestdale Middle School will become a 25 mph school zone. Trade Street currently picks back up to 35 mph leaving town past the greenway crossing. The 25 mph limit will extend beyond the crossing to allow safer pedestrian access to and from the greenway. East Charles St is currently 35 in a portion of the road but will, instead, be 25 mph along the entire length, even after the name change to Tank Town. NCDOT suggested a change on Sardis Road to 40 mph, five mph less than the current posted limit. Speed limits on portions of Weddington Road will be reduced to 35 mph, making the length of the road 35 through to the county line. The City of Charlotte oversees this portion of the road.
