Sunny skies are forecast for Saturday and Sunday, and the big orange orb in the sky means drivers will see plenty of orange barrels blocking interstate lanes for weekend road work.

Here’s where you can expect lanes to be closed:

The ramp from the Canton Road Connector to I-75 southbound in Cobb County will be closed from 9 p.m. Friday through 5 a.m. Saturday. Motorists wishing to go south on I-75 will have to take I-75 northbound to Barrett Parkway, exit and re-enter southbound I-75 there.

On I-575, one lane in each direction between Bells Ferry Road and Ga. 92 will be closed all weekend.
