Expanding the remaining 44 miles from Early to Moville, however, is expected to cost $275 million -- or up to $8.5 million per mile.

Judging by the signage in the video:

• One for the "exit number = highway number" thread: the new interchange with US 71 is Exit 71.
• IA 196 has been extended to meet US 20 at a new interchange northeast of Sac City, with County Road N14 continuing northward. I couldn't make out the exit number, though.
• The US 20 shields are mounted on two poles, a la Minnesota.
