Chronicle Staff Report Mayor Allen Joines and Creative Corridors Coalition Board Member Joycelyn Johnson celebrated the lighting of the Twin Arches at the intersection of U.S. 52 and Research Parkway on Tuesday, Jan. 30. The new lighting feature is capable of changing colors. The arches, which are meant to be an iconic monument to the city, cost $1.6 million, with 80 percent covered by a federal grant and with the City of Winston-Salem and Creative Corridors putting in 10 percent a piece. The arches were erected as the Research Parkway intersection was created and the exit to Winston-Salem State University and Salem College was deconstructed.
