After spending the past few days exploring the countryside of Western New York, Northeast Ohio and Western Pennsylvania, I decided that this week's Throwback Thursday would pay homage to an August 2004 trip that I made to the Keystone State. I had taken PA 28 on my way northeast from Pittsburgh and encountered a bunch of old signage along the way from Pittsburgh to Kittanning. The aging, button copy signs have since been replaced. This particular example is on PA 28 northbound at the Blawnox exit, near Aspinwall and Blawnox. It even looks like the Exit 9 may have been tacked on the sign as an afterthought.
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.
