I only ever take the Skyway and it's rarely that much more than 90 minutes, but maybe up to 2 hours. Don't go during rush hour into the city obviously.
Indiana is really one of the worst states in the country, though. At least Wisconsin and Michigan have some nice scenery upstate or along the lake (even most of Indiana's shoreline is industrial wasteland).
You need to take another trip over there. Fricking 90 is a disaster and the Indiana Toll Road is becoming a disaster too.
Southern IN is pretty nice and scenic. You have to go about 45 minutes south of South Bend and drive US-30 to get anything that resembles scenic. But for the most part Indiana blows chunks.
