After a week of foggy and drizzly weather, skies have finally cleared just in time for the weekend, but that means road crews will be out in full force, closing interstate lanes for construction.

Here’s what you need to know to avoid the expected traffic bottlenecks:

Interstates 20, 285 expected to be worst trouble spots

Bridge joint repairs will shut down three westbound lanes of I-20 between the Downtown Connector and Lee Street, beginning at 9 p.m. Friday and continuing through 5 a.m. Monday, and one eastbound lane of I-20 between Fulton Industrial Boulevard and I-285 from 9 p.m. Friday through 6 p.m. Sunday.

East of Atlanta, bridge repairs in Newton County will shut down a lane of I-20 eastbound between Almond Road and U.S. 278 all weekend.

More bridge repairs will close two eastbound lanes of I-285 at I-75 in Cobb County from noon until 4 p.m. Saturday.

Sign structure work will block two northbound lanes of I-285 between I-85 and Washington Road throughout the weekend, while other sign work will close three northbound lanes of the Perimeter from I-20 to Ga. 400 on the west side from 7 p.m. Friday through 5 a.m. Monday.

Sunny skies forecast for most of the weekend

Channel 2 meteorologist Brad Nitz is forecasting sunny skies for Friday, Saturday and Monday, but Sunday will be mostly cloudy with a 20 percent chance of showers late in the day.

Afternoon highs through Monday will be in the low to mid-50s, with morning lows in the mid- to upper 30s, Nitz said.

Boat show, Passion 2015, King Day March highlight weekend events

The Georgia World Congress Center will be the epicenter of weekend events, as the convention hall hosts the annual Atlanta Boat Show, the Passion 2015 religious gathering for 18-25 year olds and the “Lil’ Big South” volleyball tournament.

Passion 2015, which will also have events next door at Philips Arena, and the boat show run through Sunday, while the volleyball tournament continues through Monday.

The annual King Holiday March and Rally begins at 2 p.m. Monday, traveling from Peachtree Street to Jackson Street along Auburn Avenue.
