Nik Wallenda, the world-renowned daredevil who thrilled television viewers with his high-wire walks across Niagara Falls and the Grand Canyon, will be walking across a wire stretched high above the Georgia Dome’s floor during Saturday night’s Winter Jam Christian music concert that highlight’s this weekend’s light schedule of downtown activities.

Other events include Saturday night’s Hawks-Memphis game at Philips Arena.

With cool but clear weather forecast for most of the weekend, the Georgia Department of Transportation has scheduled roadwork in several spots around metro Atlanta.

On I-85, sign work will require two left lanes to be closed in both directions all weekend between Clairmont and Lenox roads.

Closer to downtown, the three left northbound lanes of I-75/85 from Martin Luther King Jr. Drive to Pine Street will be closed for sign work each night this weekend.

Also nightly, three left lanes of the southbound Downtown Connector at Freedom Parkway will be closed nightly for bridge work.

Motorists can also expect occasional lane closures all weekend around the Ga. 400/I-85 Interchange project, according to a GDOT spokesman.

Channel 2 meteorologist Karen Minton’s weekend forecast calls for a 20 percent chance of light rain – possibly mixed with a few snow flakes – Saturday morning, followed by clearing skies during the afternoon. Lows in the mid-30s will be followed by afternoon highs in the mid-50s.

Sunday will be sunny, with highs in the upper 50s and lows in the upper 30s, Minton said.
