The southbound approach to the Clark Memorial Bridge will be reduced to one-lane beginning Monday morning.Crews will be dismantling historic limestone pylons and railings, officials from the project said. The structures will be reincorporated into the bridge once ramp construction is complete.The work will eventually move into the northbound approach, closing one lane in each direction.The existing four travel lanes on the Clark Memorial Bridge will not be affected during the work.Pedestrian access will continue throughout construction. Northbound access will be available during southbound construction. When the work moves into the northbound lane, pedestrians will have access in the southbound lane.“We heard people’s concerns about the loss of pedestrian access, and we have responded,” Andy Barber, KYTC Downtown Crossing project manager, said in a statement.Mindy Peterson, spokesperson for the Ohio River downtown bridges project, said there is no reason to believe the work should extend beyond the set schedule.“We’re hopeful it won’t lead to too many delays,” she said. “We’ve been fortunate, even though we have had some very cold weather, we have been able to keep schedules on track. So, there is no reason to think that this is something that would extend beyond what the scheduled timeline is right now.”The lane restrictions will remain until the bridge closes for ramp construction in late May. Nearly 25,000 vehicles cross the Clark Memorial Bridge daily.
