The finishing touches were being put on the downtown traffic patterns Wednesday as signs and orange cones went up on Ewing Street. Because of rain Tuesday, the painting of lines on the street was delayed. Ewing's conversion from one-way to two-way traffic was supposed to be completed Wednesday afternoon. After Ewing is converted the construction of a roundabout will begin. The roundabout will create five-way traffic with Ewing, Fairfield, Superior and Wells.
