The bridge opened in December, 1997, after being put behind by the collapse in May,1995. Other parts of the road had been finished at that time to Clifton. Shortly thereafter, the road was upgraded from Clifton to US-64. It just seemed like they would redo a section and put the old road number back on it. Seems like no one in the area would do much more than gripe about it being aggravating. There is, sadly to say, animosity in the area with one city not wanting the other to get something they don't have, so no one ever brought it up. There are many advantages to having a smooth numbering system and having a "US Hwy" pass through your city.
I kinda helped get this started about 5 years ago when I emailed our state representative and asked if we could not get this renumbered. He agreed and checked in on it. They had to pass resolutions and then every city and county the road passed through had to pass resolutions supporting it, then they had to send it to Washington to get approval since it was a "US Hwy". It's took that long just to get this done but so glad it's finally done!
