A new traffic light at Grayson High School is expected to begin operating when school gets out on the afternoon of Jan. 12.

The new signal on Ga. 20 at the high school access road will operate weekdays during peak school hours from 6:30 a.m. to 8 a.m. and 1:30 p.m. to 3 p.m.

The new signal is part of the state Department of Transportation’s effort to widen Ga. 20 to a four-lane divided highway from Cooper/Ozora Roads to Brand Road.
