Washington State Route 310

Washington State Route 310 is a small approximately 1.8 mile state highway connecting WA 304 in downtown Bremerton to the WA 3 freeway.  WA 310 was created in 1991 as a connector route between WA 304 to WA 3 and runs entirely on a former surface alignment of the latter.

I began WA 310 from the terminus at WA 304 on Callow Avenue. 






After a short jog on Callow Avenue WA 310 turns westward on Kitsap Way.





WA 310 follows Kitsap Way westward up a hill where it terminates at WA 3.







WA 3 was built up to a freeway from WA 16 north to WA 305 during the 1970s.  Originally the routing of WA 3 and the precursor route WA PSH 21 (prior to the 1964 highway renumbering) was following alignment:

-  Charleston Avenue, Callow Avenue and Kitsap Way in Bremerton
-  Chico Way in Chico
-  Silverdale Way in Silverdale
-  Viking Avenue in Scandia

The original alignment described above can be seen by observing WA PSH 21 on the 1956 Washington State Highway Map.

Onion Valley Road; former California State Route 180 to Kearsarge Pass

This summer I had an opportunity to drive one of the lesser known great roads of California; Onion Valley Road from Independence west to Onion Valley near Kearsarge Pass.  Aside from being massive climb into the Eastern Sierra Nevada Mountains the path of Onion Valley Road was once signed as California State Route 180 and was intended to be part of a Trans-Sierra Highway.


Onion Valley Road is located west of Independence of Inyo County and is 12.9 miles in length.  According to pjammcycling.com Onion Valley Road begins at an elevation of 3,946 feet above sea level in Independence and terminates at 9,219 feet above sea level at Onion Valley.  Pjammcycling rates Onion Valley Road with an average gradient of 7.8% and lists it as the 6th most difficult cycling climb in the United States.  Onion Valley Road also includes ten switchbacks which largely follow the course of Independence Creek.  Anyway you look at it the route of Onion Valley Road is no joke and is definitely a test of driving…

Trans-Sierra Highways; California State Route 4 over Pacific Grade Summit and Ebbetts Pass

Back in late October of 2016 I had a long weekend off which coincided with a warm weekend in the Sierra Nevada Mountains.  That being the case the winder in the weather gave me a chance to finish some additional Trans-Sierra Highways starting with California State Route 4 over Pacific Grade Summit and Ebbetts Pass.  I would later return to Pacific Grade Summit and Ebbetts Pass during the smoke filled summer of 2020. 

California State Route 4 ("CA 4") contains probably most infamous Trans-Sierra State Highway in Caltrans Inventory.  CA 4 from CA 207 in Bear Valley east over Pacific Grade Summit and Ebbetts Pass includes approximately 30 miles of one-lane highway which reaches gradients as steep as 24%. 
CA 4 is a 192 mile State Highway which originates at I-80 near Hercules of the San Francisco Bay Area and terminates at CA 89 in the remote Sierra Nevada Mountains of Alpine County.  CA 4 is probably the most diverse State Highway in California as it has; several freeway segme…

Horseshoe Meadows Road; former California State Route 190 and the legacy of the Lone Pine-Porterville HIgh Sierra Road

This summer I had an opportunity to drive one of the lesser known great roads of California; Horseshoe Meadows Road from Whitney Portal Road westward into Horseshoe Meadows of the Eastern Sierra Nevada Mountains.  Aside from being massive climb into the Eastern Sierra Nevada Mountains the path of Horseshoe Meadows Road was once part of California State Route 190 and was intended to be part of a Trans-Sierra Highway known as the Lone Pine-Porterville High Sierra Road.


Horseshoe Meadows Road is located west of Lone Pine of Inyo County and is 19.7 miles in length.  Horseshoe Meadows Road begins at an approximate elevation of 4,500 feet above sea level at Whitney Portal Road in the Alabama Hills and ends at an elevation of 10,072 feet above sea level in Horseshoe Meadows.  Horseshoe Meadows Road is the second highest paved road in California only behind Rock Creek Road near Tom's Place.  Pjammcycling rates Horseshoe Meadows Road with an average gradient of 6.2% and lists it as th…
