(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:

(WXIA) -- The Washington Post has unveiled its 2014 list of America's Most Challenging High Schools.

The newspaper determines the annual rankings through a ratio: the number of Advanced Placement, International Baccalaureate and Advanced International Certificate of Education tests a school gives each year, divided by the number of graduating seniors.

Nine DeKalb County schools made the list, which features more than 2,000 high schools across the country. The listed numbers are each school's national ranking.

178. DeKalb School of the Arts
325. Chamblee Charter HS
606. Tucker HS
808. Dunwoody HS
935. Lakeside HS
1241. Druid Hills HS
1666. Southwest DeKalb HS
1687. Arabia Mountain HS
1962. Cross Keys HS

Additionally, Decatur High School, which is part of a charter system, is No. 205 on the list.

(WXIA) -- Rain is in this weekend's forecast, but that won't stop Georgia Department of Transportation from working on scheduled road projects throughout the area.

GDOT District Construction Engineer Shun Pringle said the department expects more people than usual on the road, as school districts begin and end their spring breaks.

"Call 511 or look at a mapping website before you leave home," Pringle said in a statement. "Motorists, including spring breakers ... need to plan ahead to avoid delays."

The new flyover ramps on the Interstate 85/Georgia 400 Interchange project are open, but crews still need to perform a little last-minute work on them. Lanes will be closed in places.
