Taken from the Gribblenation Facebook page.  Made a significant find regarding the 7th Street Bridge which confirms it was part of Legislative Route 4 and 1926-1933 US Route 99:

I recently paid a visit to the 7th Street Bridge *also known as the "Lion Bridge") which spans the Tuolumne River on the southern outskirts of Modesto.   The 7th Street Bridge is slated to be replaced and demolished in 2023-2024 due to having a structural sufficiency rating of 2 (which is bad enough that vehicles exceeding 4 tons can't cross).  While the often cited build year of 1916 for the 7th Street Bridge is well documented what often doesn't discussed is that it was part of Legislative Route Number 4 and US Route 99 until July 1933.   The 7th Street Bridge was for it's time a modernized replacement of a previous Pennsylvania Truss span.   The 7th Street Bridge is a concrete arch span which is 1,170 feet in length. 

-  Photo 1 below shows the 7th Street Bridge facing north from River Road.
-  Photo 2 below is the 1917 California State Automobile Association Map which shows the 7th Street Bridge as part of Legislative Route Number 4. 
-  Photos 2-8 are from the October/November 1932 and July/August 1933 California Highways & Public Works.  Both Volumes of the CHPW discuss the replacement of the 7th Street Bridge which a new structure over the Tuolumne River via 9th Street. 
-  All remaining photos show the 7th Street Bridge as it presently exists in modern times.
