Any of you who have driven Interstate 5 through Tacoma will know how much this project impacted traffic. The basic idea was to add one HOV lane in each direction but that involved removing every overpass along the way and replacing most of them. The freeway itself runs on bridges in the downtown area which meant replacement of those. The I-5 / WA-16 interchange was particularly difficult which ending up being redone again as measurements were miscalculated along the way.
