The state highway runs 35.39 miles (56.95 km) from Camp Peary near Williamsburg east to U.S. Route 258 (US 258) at Fort Monroe in Hampton. SR 143 is a major local thoroughfare on the Virginia Peninsula portion of the Hampton Roads metropolitan area. The state highway is named Merrimac Trail through the independent city of Williamsburg and adjacent portions of York County and James City County. SR 143 follows Jefferson Avenue through the city of Newport News from the Williamsburg area past Newport News/Williamsburg International Airport to near Downtown Newport News. The state highway, which mostly runs northwest–southeast, heads northeast from Newport News, serving as one highway connecting the downtown areas of Newport News and Hampton. SR 143 parallels both US 60 and Interstate 64 (I-64) extensively, and sometimes very closely, throughout its course. The state highway also runs concurrently with US 60 in Hampton and with US 17 in Newport News.
