(WXIA) -- The Georgia Department of Transportation will work on a number of infrastructure projects on Atlanta's highways this weekend.

Drivers are strongly encouraged to avoid Interstates 20 and 285 on the west side of the city, as well as I-75 south of the Perimeter, if possible.

As always, all work is weather permitting.

Scheduled projects include:

Bartow County
* 2 southbound lanes of I-75 will be closed between one mile south of Emerson-Allatoona Road and two miles north of Glade Road Saturday from 7 a.m. to 5 p.m. for bridge maintenance.

Clayton/Henry counties
* 2 northbound lanes of I-75 will be closed between Hudson Bridge Road/Eagles Landing Parkway and Mount Zion Boulevard from 9 p.m. Friday to 9 p.m. Sunday for concrete slab replacement.

(WXIA) -- A major project on a heavily traveled interchange is bound to cause some headaches for Atlanta-area drivers this weekend.

It's just one of several scheduled construction sessions throughout the area. All work is weather permitting.

Crews will be hard at work on the Kennedy Interchange in Cobb County much of the weekend. The Kennedy Interchange is where Interstate 75 meets Interstate 285 in the Cumberland area.

The Georgia Department of Transportation said sign installation will require multiple lane closures on the Outer Loop of I-285 just before the exit ramp to Cobb Parkway and I-75 north. Two right lanes will close at 9 a.m. Saturday; that will expand to three lanes between 11 p.m. Saturday and 8 a.m. Sunday. Outer Loop traffic will also be paced in the area beginning at around 2 a.m. Sunday.

Other weekend road projects include:
