US 630 #1: Appeared as the highest number in the 1925 proposed US Highway System. Ran from US 91 (now UT 26) Ogden UT to US 30 (now Echo Dam Rd) Echo City. This would've replaced UT 5.
In January 1926 (AASHO), as part of US 30 being rerouted over US 20 to head to Astoria OR, US 630 became part of US 30S. Today this is US 89 Ogden to Uintah; mostly I-84 and UT 167 to Mountain Green; Old Highway Rd to Morgan; mostly I-84 to Exit 112 (used Taggert Ln); UT 86 to Henefer; Center St (cutoff by I-84) and S Henefer Rd; South Echo Rd to Echo Dam Rd.
US 630 #2: Appeared July 1926 (AASHO) as a renumbering of US 320 as a downstream effect of US 30 replacing US 20. Ran from US 30 (now OR 201) Weiser Jct OR to US 95 (State St at Main St) Weiser ID. This was just 3 miles. The December 1926 Idaho State Highway Status map in the 1926 Biennial Highway Report showed US 630 replacing US 95 south to US 30 Ontario Junction, extending US 630 to a length of 23 miles. When AASHO sent Idaho its list of US Highways to confirm and correct any errors, Idaho replied March 4, 1927 that US 630 actually continued south of Weiser through Payette to end at US 30 Ontario Junction which is very near Fruitland. They also indicated that US 95 ended at US 630 Weiser and not Ontario Junction. A follow-up communication from Idaho on March 10 reiterated that US 630 ran to Ontario Junction. The March 3 telegram also requested that AASHO renumber US 630 as US 30N. On May 2, 1927 AASHO informed Idaho that US 630 became US 30N. Today this is US 95 Spur from Weiser Junction OR to Weiser (used Main St); US 95 south into Payette County; Scotch Pines Rd/19th Ave/Iowa Ave/7th Ave/9th St to Payette; 3rd Ave/Main St out of Payette; US 95 to the Payette River; Alder Rd (no longer connected to)/North Alder Dr; US 95 to US 30. Most maps that showed US 630 at all showed just the 3 mile segment from Weiser west to US 30 in Oregon. But I found one commercial map that showed it to Ontario Junction. Idaho reported that 60% of its US routes were posted in 1927. Since Idaho was trying to change 630, it seems very unlikely that this was posted.
