Sandy Springs has installed new, digital, turn-restriction signals at Edgewater and Riverside drives that have the effect of discouraging cut-through traffic in a residential area during the morning and afternoon rush hours.

“Due to the irregular configuration of the intersection, the city wanted to make the traffic signs more easily visible to commuters,” according to a city announcement.

A 2018 study found about 41 percent of morning traffic through the neighborhood used the route off of Riverside as a cut-through to avoid the intersection of Riverside and Heards Ferry Road, the city said. (Edgewater leads to a series of streets that ultimately emerge onto Heards Ferry west of Riverside.)

“While the signals are new, the turn restrictions remain the same,” the city said: Between 7 and 9 a.m. weekdays, right turns are restricted from southbound Riverside to westbound Edgewater; while from 4 to 6 p.m. weekdays, left turns are restricted from eastbound Edgewater to northbound Riverside.
