We are heading down I65 next week pulling our 5th wheel. I understand that there is bridge construction. Is there a detour? Is it clearly marked? Don't want any surprises.
If you are heading south, why don't you take I-265 around Louisville to Bowling Green. This is what we do when heading to Florida or Texas. I'm not sure if this avoids the bridge you are talking about as I can't remember a bridge along this route being under construction.
