The signed Route 9, as LRN 114, proceeded North on Saratoga-Sunnyvale Road into Sunnyvale via Mathilda Ave, thence to a jct with Alviso-Milpitas Road (currently signed as Route 237), and a junction with Bypass US-101 (LRN 68). On October 18, 1956, the Highway Commission adopted the routing for a future freeway location for Route 9 from Bayshore Freeway north of Moffett Field, generally following Stevens Creek to an existing Route 9 location north of Azule near Saratoga. The route signed as Route 9 then proceeded on the current Route 237 alignment into Milpitas. It ran east as Route 237 to Route 17 (LRN 69; now I-880).
Before the current bridge over the Guadalupe River was constructed, it took a route into Alviso via Gold Street north and 1st Street southwest back to current Route 237.
In August 2011, the CTC approved $479,000 in SHOPP funding to stabilize and repair slope at four locations in Saratoga, from Skyline Boulevard (~ 009 SCL 0.026) to Toll Gate Road (~ 009 SCL 6.678), damaged by heavy rainfall.
In June 2011, the CTC approved for future consideration of funding a project that will make safety upgrades on Route 9 from 2.5 miles north of Route 35 (~ 009 SCL 2.5) to 6th Street, near Saratoga (~ 006 SCL 7.099). The project is programmed in the 2010 State Highway Operation and Protection Program.
Phase four is expected to be completed by the end of 2017.
