Drivers on the I-6 highway between Sofia and Burgas face temporary changes near Aytos from 10:00 on 30 September, the Road Infrastructure Agency says. The work is on a toll gantry, and the change will stay until it's done.

The work site is at the 473rd kilometre, near the town. On the lane heading from Burgas to Aytos, the road narrows and cars will move into the free lane.

Traffic police and staff from the Burgas regional road department will direct cars if needed. The agency is asking drivers to watch for road signs, stay alert, slow down and avoid risky overtaking.
