After you leave greater Indianapolis, you won't stop much until Kokomo, which does have a lot of stoplights. After that it's pretty smooth sailing until you get to the towns just south of South Bend. The other alternative is to take I-65 to I-80 (Indiana toll road). This way is all interstate, but is 70 miles further and will take longer without a doubt.

It's two lanes each way and there aren't many stoplights so it's a very quick route. Once you get through Kokomo it's smooth sailing. I actually enjoy the drive quite a bit because of how quickly you move along. Taking I-65 to the toll road in Northeastern Indiana is another way, but it wastes far too much time. As for the construction concerns, I just checked INDOT's website and they report no road closures for construction anywhere along the way.
