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.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926. Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California. The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant. However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices. This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes. The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield. In the background Mount Whitney can be seen in the Sierra Nevada range. ...

Hawaii Route 50

Hawaii Route 50 is the longest Sign Route on the island of Kauai at 32.6 miles. The entirety of Hawaii Route 50 is overlaid atop Kaumualii Highway from Lihue west to the Pacific Missile Range Facility at Barking Sands. Hawaii Route 50 is one of the original 1955-era State Highway designations on Kauai. Much of the Kaumualii Highway corridor was constructed during the sugar plantation boom of the late Hawaiian Kingdom. The first tee beam bridge in Hawaii would be constructed along the Kaumualii Highway in 1911 at the Hanapepe. Much of this highway would be modernized to two-lane standards through the 1930s and 1940s. This page is part of the Gribblenation Hawaii Roads series.

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida. One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region. For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate. Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century. Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area. The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...
