Corky Kell Classic, I-285 roadwork this weekend

Get ready for another heavy round of weekend roadwork on several stretches of I-285 and other metro Atlanta interstates.

Here’s what you need to know to avoid the backups:

Biggest trouble spot will be I-285: "There are times you simply don't want to be on I-285," Georgia Department of Transportation spokesman David Spear said. "This weekend promises to be one of those times."

Concrete slab replacement will shut down two northbound lanes of the Perimeter between South Cobb Drive and Paces Ferry Road, beginning at 9 p.m. Friday and continuing through 5 a.m. Monday.

South of there, two northbound lanes will be closed between Old National Highway and Washington Road for bridge joint repairs, from 9 p.m. Friday through 5 p.m. Saturday.

On the top-end Perimeter, continuing sign work will close two eastbound lanes and one westbound lane between I-75 and Northside Drive all weekend.

Other problem areas: Workers in Newton County will close two eastbound lanes of I-20 between Almon Road and U.S. 278 all weekend for resurfacing.

On I-75, two northbound lanes between Howell Mill and Moores Mill roads will be closed all weekend, and one lane in each direction will be closed between the Brookwood Interchange and Deering Road from 9 p.m. Friday until noon Saturday and again from 5 p.m. Sunday until 5 a.m. Monday.

All the work is weather permitting. For updated traffic info, check the WSB 24-hour Traffic Center.

About that weather: The weekend will begin hot, but temperatures will be a little cooler on Sunday as the chance of rain goes up.

Channel 2 meteorologist Karen Minton said highs will be in the mid-90s Friday and Saturday and and in the upper 80s Sunday, with lows in the 70s.

Minton put the chance of rain at 20 percent Friday, 30 percent Saturday and 60 percent Sunday. Full weekend weather forecast.

Weekend events roundup: The Falcons take on the Tennessee Titans in preseason play at the Georgia Dome at 7 p.m. Saturday, while the Atlanta Dream plays the Chicago Sky in the WNBA Eastern Conference Semifinals at 7:30 p.m. Friday.

The hot temperatures could be an issue for this weekend's full slate of high school football games, including the Corky Kell Classic, which this year moves from the controlled climate of the Georgia Dome to McEachern High School in Powder Springs because of the Falcons game. Two games will be played Friday night at McEachern, with Saturday's five games scheduled to begin at 9 a.m.

Other weekend events include the Grant Park Summer Shade Festival Saturday and Sunday, the Pigs & Peaches BBQ Festival Friday and Saturday at Adams Park in Kennesaw, the International Woodworking Fair Friday and Saturday at the Georgia World Congress Center and Sunday's Festival Peachtree Latino at Piedmont Park.
