A Salt Lake Tribune article (see here) says that officials are trying to get the Legacy Parkway designated as a National Scenic Byway. In the article Woods Cross City Manager Gary Uresk is quoted as saying that the designation would give the highway some recognition and attract tourists. It would also make Legacy eligible to receive Federal Highway Administration funds.
According to the National Scenic Byways Program (see here), a national scenic byway should be a road that has "outstanding scenic, historic, cultural, natural, recreational, and archaeological qualities." In my opinion, the Legacy Highway does not have outstanding scenic qualities. It has many of the same scenic views as I-15. From I-15, you can see the mountains to the east and the Great Salt Lake to the west. The Legacy Highway does offer better views of the two South Davis Sewer Plants, and also a better view of the Bountiful Landfill. I don't see how this highway has outstanding historic, cultural, natural, recreational or archaeological qualities. The highway was built with the main purpose of providing an alternate to I-15. Anyone who says otherwise, doesn't know the true history of this highway. It was a compromise that made it anything other than just another highway through suburbia.
This sounds like a scam to get extra money from the federal government. Let's be responsible citizens of this country and save money designated for national scenic byways for those roads that have "outstanding scenic, historic, cultural, natural, recreational, and archaeological qualities."
