(WXIA) -- Only one major daytime closure will affect drivers on Atlanta's highways this weekend.

The leftmost lane on I-285 north will be closed between I-20 and Ga. 400 on Saturday from 9 a.m. to 4 p.m. Crews must close the lane to remove a barrier wall.

"With only that one closure on I-285, everyone should have an easier time getting to their destination," Georgia Department of Transportation District Construction Engineer Shun Pringle said in a statement.

Nighttime closures will still occur in a handful of locations.

Three right lanes of I-20 west between Wesley Chapel and Candler roads will be closed for striping every night from 8 p.m. to 6 a.m.

Two left lanes of I-285 north between I-20 and Peachtree Dunwoody Road will be closed nightly from 9 p.m. to 5 a.m. Crews will work to replace a barrier wall in that location.

Other scheduled closures for sweeping, drain cleaning and slab replacement include:

COBB COUNTY, Ga. -- Cobb County Fire Department's Heavy Rescue Unit credit their specialized training and equipment with helping to rescue two women trapped under the massive trunk of a tree that came crashing down on their house.

Firefighters say their first task was making sure the house, which was heavily damaged by the downed tree, didn't collapse around them.

Once they'd stabilized the damaged structure, firefighters turned their attention to the trapped women.

Lt. Robert Hiller says the rescuers used specialized inflatable airbags to lift the trunk off the women's legs.

Firefighters say the rescue operation was a race against the clock. Lt. Hiller says typically people who have suffered a traumatic injury need to get to a hospital within an hour to give them the best odds of survival.

MARIETTA, Ga. -- Sicily Kolbeck is just like any other 13 year-old doing her homework on a Friday night.

But unlike any other 13 year-old, she's doing it in the comfort of her own home. The one she designed and built from the ground up.

"My dad was a packrat, so he had all the tools we needed," she said. "We probably needed to buy like three tools."

The little house in Marietta, all 128 square feet of it, is called La Petite Maison. It started out as a homework assignment from her teacher, who's also her mom.
