One lane of Oakland Avenue was blocked off Tuesday as city crews continued upgrading three intersections near the Winthrop University campus.
The lane has been blocked off and on for the past few weeks as part of a project that began in 2009.
Scott Motsinger, public utilities director for the city of Rock Hill, said the city, Winthrop University and the S.C. Department of Transportation have been working on upgrading the mast arms at the intersections of Oakland Avenue and Eden Terrace, Oakland Avenue and Stewart Avenue and Oakland Avenue and Myrtle Drive.
Mast arms are the brackets that hang over the street and from which the traffic lights are suspended. The difference between a regular mast arm and the new ones will be that the new ones don't use overhead wires.

The city received a $150,000 Congestion Mitigation and Air Quality Improvement grant from DOT to work on the intersections. Winthrop officials expressed an interest in upgrading to the newer mast arms.
There is no timetable set for when the upgrades will be completed, but Motsinger said they are working with the university to make sure traffic is never blocked in both lanes and that it doesn't affect university scheduling or events.
