California State Route 84 over the Santa Cruz Mountains from I-280 west to CA 1

On a recent trip in the Bay Area I drove California State Route 84 over the Santa Cruz Mountains from Interstate 280 west to CA 1.


CA 84 between I-280 west to CA 1 lies entirely within San Mateo County.  The route of CA 84 over the Santa Cruz Mountains was originally defined as part of Legislative Route Number 107 in 1933 which only west to LRN 55 (modern CA 35) at Skyline Boulevard.

Interestingly the original alignment of LRN 107 west of Woodside doesn't appear to be State Maintained as of 1935.  The California Division of Highways Map from San Mateo County in 1935 shows La Honda Road west of Woodside to LRN 55 as a County Maintained.

LRN 107 first appears west of Woodside on La Honda Road to LRN 55 on the 1936-37 State Highway Map.

In 1959 the definition of LRN 107 was extended west from CA 5/LRN 55 to CA 1/LRN 56 near San Gregorio.  This new extension of LRN 107 first appears appears on the 1960 State Highway Map.

According to CAhighways.org the route of CA 84 was applied over LRN 107 in 1961.

CA 84 first appears on the 1962 State Highway Map signed over the entirety of LRN 107 and LRN 108.

My approach to CA 84 west over the Santa Cruz Mountains was from I-280 south.  From Exit 25 on I-280 south on pulled onto CA 84 west on Woodside Road.




CA 84 west follows Woodside Road through Woodside.  Woodside dates back to 1849 and is mostly known for it's lumber days when Redwood Sequoias were milled in the area.



Traffic on CA 84 west in Woodside that trucks over 30 feet in length are not recommended.


One of the few reassurance shields on CA 84 west in the Santa Cruz Mountains appears in Woodside past Canada Road.



West of Woodside CA 84 follows Woodside Road through the heavily wooden Bear Gulch.







CA 84 west makes a turn onto La Honda Road.



CA 84 west makes an ascent to the crest of the Santa Cruz Mountains on La Honda Road.  La Honda Road is very curvy and was being overwhelmed by water flowing down out of the Santa Cruz Mountains.
















CA 84 west meets CA 35 on Skyline Boulevard at the ridge of the Santa Cruz Mountains.  Unfortunately someone had stolen all the CA 35 shields at pretty much every junction on Skyline Boulevard.



CA 84 west of CA 35 on La Honda Road follows La Honda Creek and begins to descend from the crest of the Santa Cruz Mountains.







CA 84 west meets Old La Honda Road on it's descent through the Santa Cruz Mountains.


Old La Honda Road is a single-lane old logging road that features steep grades and sharp drop-offs.

CA 84 west on La Honda Road continues to follow La Honda Creek to community of the same name.  La Honda dates back to the 1860s and much like Woodside was center around lumber mills.









West of La Honda CA 84 picks up San Gregorio Creek.


CA 84 west follows San Gregorio Creek into an ever widening expanse of lush canyons approaching San Gregorio.










At the intersection of Stage Road CA 84 west enters San Gregorio.


San Gregorio dates back to the 1850s and still has an appearance of an early Gold Rush Era community.  The San Gregorio General Store has been in operation since been operation since 1889.


Stage Road is a very early alignment of CA 1 and appears on the 1935 San Mateo County Division of Highways Map above.



CA 84 west terminates at CA 1 at San Gregorio State Beach.  While the end of CA 84 doesn't have much fanfare the view from the cliffs above San Gregorio State Beach are worth making the trip across the Santa Cruz Mountains to see.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l

Ghost Town Tuesday; Mannfield, FL and the stairway to Hell

Back in 2015 I went searching the Lecanto Sand Hills for the original Citrus County Seat known as Mannfield.  Unlike Centrailia in Hernando County and Fivay in Pasco County I did find something worth seeing. Mannfield is located in the Lecanto Sand Hill section of Withlacoochee State Forest somewhat east of the intersection of Citrus County Route 491 and Mansfield Road. Mannfield was named after Austin Mann and founded in Hernando County in 1884 before Citrus County Split away.  In 1887 Citrus County was split from northern Hernando County while Pasco County was spun off to the south.  Mannfield was selected as the new Citrus County seat due to it being near the county geographic center.  Reportedly Mannfield had as many as 250 people when it was the County Seat.  The town included various businesses one might include at the time, even a sawmill which was common for the area.  In 1891 Citrus County voted to move it's seat to Inverness which set the stage for the decline of M

The National Road - Pennsylvania - Great Crossings Bridge and Somerfield

West of Addison, US 40 crosses the Youghiogheny River at what once was the town of Somerfield.  When crossing the current modern two lane bridge, you many not realize that it is actually the third to cross the Yough at this site.  The first - a stone arch bridge - was known as the Great Crossings Bridge.  Built in 1818, this three arch bridge was part of the original National Road.  The name Great Crossings comes from the men who forded the Youghiogheny here - George Washington and George Braddock. (1)  If you cross the bridge at the right time, this historic bridge and what was once the town of Somerfield will appear out from underneath this massive man-made lake.

The Great Crossings Bridge was located in the town of Somerfield.  Somerfield, originally named Smythfield until 1827, would develop as a result of the National Road.
