For Throwback Thursday this week, we go back to April 2005 to US 15 in Painted Post, New York (this section of road is now part of I-99 as well). At the time, there was a sign for the Gang Mills exit where a NY 417 shield with a white background was affixed to the sign. I believe that it had to do with a maintenance swap that took place a few years prior. The sign is now long gone, replaced with something not quite unique.
In 2019 the Gribblenation Blog Series covered the history of the Hyde Street Pier and the original surface alignment of US Route 101 in San Francisco. Given the Golden Gate Bridge opened to traffic in May of 1937 coupled with the fact that the Sign State Routes had been announced in August of 1934 there were still some open questions regarding the original highway alignments in San Francisco. Namely the question of this blog is; where was California State Route 1 prior to the completion of the Golden Gate Bridge? Thanks the to the discovery of a 1936 Shell Highway Map of San Francisco and the California Highways & Public Works the answer can be conveyed clearly. Part 1; the history of early California State Route 1 in San Francisco The genesis point for California State Route 1 ("CA 1") in San Francisco dates to 1933. 1933 was significant due to the State Legislature allowing the Division of Highways to assume maintenance of highways in Cities for the first time.
