LOUISVILLE, Ky. (WHAS11) – The extensive repairs that were planned for later in January on a deteriorated support column that led to the closure last month of the ramp that carries traffic from I-65 North to I-64 West has been delayed.
On Thursday, officials from the Ohio River Bridges Project announced that the plans have been delayed due to the forecasted cold temperatures.
A number of columns in the 50-year-old interchange have damage to the outer shell, which has exposed the rebar cage. But KYTC officials said the deterioration found on Pier 9, Column 1 was the first discovery of significant deterioration of the center core of a column in the interchange.
Mindy Peterson of the Ohio River Bridges Project said the other columns inspected didn't need urgent repairs.
No new repair date has been set, but Walsh Construction Co. will remove the deteriorated concrete, replace damaged steel rebar and pour a new layer of concrete around the column to encase the repaired core. The work is expected to take less than a week and will require closure of the ramp.
Columns in the interchange are inspected every two years, and several columns with deteriorating concrete have been repaired in the past.
