It's not considered a single freeway, but taking the straight north-south route across Charleston, West Virginia using I-64 eastbound across the Fort Hill Bridge and then staying straight onto I-77 northbound shows how narrow the city is along the Kanawha River. After crossing that river, you first run parallel to the Elk River with downtown on the east side and a semi-commercial zone on the West Side. After the I-64/I-77 interchange, you enter the Elk River trench with an older residential section along the Interstate and a narrow industrial corridor on the east side. But once you get to the I-77/I-79 interchange, its almost completely forested (with a glimpse of the Yeager Airport atop the ridge to the east.
It's about 3 miles from Corridor G -to- I-79.
Should I mention that going the other way, I-64 runs alongside the huge former Union Carbide chemical complex (now Dow) in South Charleston. A drastic change in scenery, but probably not what the OP was looking for.
