Part of northbound Lake Shore Drive will remain closed through Monday’s evening commute after a bridge support beam cracked.
The Chicago Department of Transportation discovered a crack in a steel beam that supports Lake Shore over the ramp from Randolph Street Monday morning, department officials said in a statement.
“Crews are working to install a shoring tower as quickly as possible under the viaduct structure that carries northbound Lake Shore Drive,” CDOT said.
All northbound traffic was diverted from northbound Lake Shore Drive at Randolph about 11:15 a.m., according to Chicago police.
Northbound Lake Shore traffic is being detoured via Randolph, Monroe, Columbus and Lower Wacker, CDOT said. Southbound traffic is not affected.
The closure will last through Monday’s evening rush and “possibly longer,” CDOT said. Motorists are advised to use I-90/94 as an alternative route.
Vehicles can access northbound Lake Shore via Lower Wacker Drive or the entrance ramp at Grand, according to CDOT. The ramp from eastbound Randolph is closed.
