The right and center lanes of northbound Greenville Avenue between Main Street and Terrace Drive, and the right and center lanes of southbound Greenville between Apollo Road and Main Street, may be closed to traffic from 9 a.m.-3:30 p.m. for gas line work. Additionally, Terrace Drive between Greenville and La Salle Drive may be down to one lane with flaggers to direct traffic. The work is expected to wrap up in late December.
