GREENSBORO, N.C. (WGHP) — A fire has closed several roads in Greensboro Tuesday morning.

According to Greensboro Police Department, a structure fire at a commercial building used by Smith Trucking Company on Oakland Avenue is being investigated by Greensboro Fire Department.

The following intersections are closed to traffic while crews are on the scene of this fire:

  • Oakland Avenue at McManus Street
  • Oakland Avenue at Park Terrace
  • Spring Garden Street at McManus Street
