US 40 - The National Road

If there is a highway that can capture the early pioneer spirit of this nation, it is the National Road. America's Original Interstate Highway, generations of Americans have followed parts of what now is US 40 on their sojourns west. From early Indian paths to a federally funded route to the west, to a toll horse and wagon route, and finally into the automobile era, the National Road has served not only as a method of travel. It is also a source of history, commerce, recreation, and exploration.

Petroleum Club Road (former California State Route 33 and US Route 399 past the Lakeview Gusher)

This corridor was constructed as a frontage road of the Sunset Railroad and would be the site of the Lakeview Gusher in 1910. Petroleum Club Road was the original alignment of California State Route 33 and US Route 399 between 1934-1938.

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.

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.
