Police said Thursday they were directing traffic around frogs on the Egnatia Highway about 20 kilometers outside Greece's second largest city, Thessaloniki.
The frogs, leaving a nearby lake to look for food, were expected to disrupt traffic through the weekend.
Police closed a section of the road
Wednesday after three cars skidded off the road when the drivers tried to dodge the frogs.
