Motorists who use the Kennedy Memorial Bridge can expect more traffic delays this week as workers continue a major repair project.Southbound bridge traffic is still down to one lane to allow for some unexpected repair work. It will be expanded to two lanes on the morning of July 4thbut Kentucky Transportation Cabinet spokeswoman Andrea Clifford says they’ll need to shut down an additional northbound lane after that."During that day the contractors will move the barrier walls, and then at midnight we’re going to switch that traffic pattern to have one lane going northbound on the bridge and two lanes coming across southbound," she said.Clifford says the work is also requires some ramp closures in Spaghetti Junction.The entire bridge deck replacement project is scheduled for completion by mid-August. Clifford says the extreme heat has not caused any major problems.
