Construction is planned this weekend on numerous stretches of metro Atlanta interstates, but there’s a good chance rain could delay some of the planned lane closings, since all of the roadwork is weather-permitting.

Here’s what you need to know to avoid the roadwork and raindrops.

I-285 to be the hot spot this weekend

Three lanes of I-285 northbound and southbound will be closed at Atlanta Road nightly from 9 p.m. to 5 a.m. One lane of Atlanta Road in each direction will also be closed nightly.

Also on I-285, three lanes in each direction between Memorial Drive and East Ponce de Leon Avenue will be closed from 9 p.m. to 5 a.m. nightly for lane striping.

Two southbound lanes of I-285 will be closed from South Cobb Drive to Martin Luther King Jr. Drive from 9 p.m. Friday through 5 a.m. Monday, while two northbound lanes will be closed during the same hours between I-85 and Bolton Road.

Rain could delay roadwork

Highs will be in the low to mid-80s, with lows in the low 70s, Minton said.

While Tropical Storm Erika is not expected to impact Georgia’s weather over the weekend, the National Hurricane Center’s forecast puts the storm near south Florida by early Monday morning and near the Florida-Georgia state line by early Wednesday.

The storm could bring gusty winds and heavy rain to parts of Georgia by the middle of next week, the National Weather Service office in Peachtree City said early Friday.
