Motorists driving through Cobb County on I-75 this weekend can expect big delays as crews shut down one interchange and close other interstate lanes for construction.

“The I-75/North Loop area in Cobb County is likely to be a very slow ride all weekend,” said Shun Pringle, a district construction engineer for the state Department of Transportation. “The surface streets around the North Loop interchange will be very crowded.”

Beginning Friday night and for the next five weekends, the DOT will completely close the North Marietta Parkway, or North Loop, from Cobb Parkway to Gresham Road to make concrete repairs. The closures will include the exit ramps to the North Loop from I-75 northbound and southbound.

Just north of there, the DOT plans to close two southbound lanes of I-75 from Chastain Road to Ga. 5 from 9 p.m. to 5 a.m. each night this weekend.

The construction is weather permitting, and judging from Channel 2 meteorologist Karen Minton’s forecast, the weather should be conducive to road work, with sunny, dry weather expected through at least the middle of next week.

Weekend highs will be in the upper 70s to low 80s, with lows in the upper 50s.

That forecast will be perfect for outdoor events such as the Atlanta Pride Festival Saturday and Sunday at Piedmont Park. The Pride Parade will step off at 1 p.m. Sunday and travel from the MARTA Civic Center station north on Peachtree and end at the park.

Other events this weekend include the Georgia State-Troy football game at 3:30 p.m. Saturday at the Georgia Dome, and Saturday’s 6 p.m. game pitting Clark-Atlanta against College of Faith.

There will be early traffic Saturday on roads headed toward Athens, where the University of Georgia plays Missouri at noon.

South of town, Falcon Field in Peachtree City will be hosting the Great Georgia Air Show through Sunday.
