The closure, which begins Friday at 10 p.m. and ends Monday at 5 a.m., is due to a second work blitz on the bridge.
Workers will connect the new Nuns’ Island Bypass Bridge to the current Champlain Bridge corridor toward the South Shore.
According to the bridge work schedule, there will be more lane closures on the Champlain next weekend.
There will also be closures on Highway 15, the Nuns' Island Bridge and the Bonaventure Expressway between Oct. 17 and 20.
