With no rain in the forecast, motorists can expect an abundance of roadwork this weekend that transportation officials said will likely jam stretches of metro Atlanta interstates.

Here’s what you’ll need to know to avoid the trouble spots:

I-75 detour in Cobb tops list of roadwork

Southbound traffic on I-75 will be directed off the interstate at the Barrett Parkway exit, then across Barrett Parkway and back onto the entrance ramp to the interstate, beginning at 9 p.m. Friday and continuing through 5 a.m. Monday, for Express Lanes construction.

Other weekend-long Express Lanes construction closures on I-75 include one lane in each direction between Chastain and Wade Green roads and one southbound lane between South Marietta Parkway and Delk Road.

On I-575, Express Lanes construction will block one lane in each direction between Barrett Parkway and Chastain Road from 9 p.m. Friday through 5 a.m. Sunday and one lane in each direction between Ga. 92 and Ga. 140 nightly.

Express Lanes work will also block one westbound lane of I-285 between I-75 and Cobb Parkway, beginning at 9 p.m. Friday and continuing through 5 a.m. Tuesday.

Elsewhere, work on the South Metro Express Lanes will require various lane closures on I-75 northbound and southbound between Jonesboro Road and Hudson Bridge Road from 9 p.m. Friday through 7 a.m. Monday.

On I-20, two lanes in each direction will be closed between Hamilton E. Holmes and Martin Luther King Jr. drives all weekend, while east of Atlanta, two eastbound lanes will be closed from Almon Road to Ga. 142 throughout the weekend.
