The National Road - Pennsylvania - Brownsville and Dunlap's Creek Bridge

Image
By
From Searights Toll House, the National Road continues west towards the Monongahela River town of Brownsville.  Brownsville for many decades was a transportation and industry center.  Brownsville was the home to steamboat construction and a rail hub for the steel industry.  Like many cities and town's in what is now known as the Rust Belt, Brownsville saw a steady and dramatic population decline after the Second World War.  Brownsville's population peaked at just over 8,000 residents in 1940 to nearly a quarter of that today.  (The estimated 2016 population is 2,270.)

 The heart of Downtown Brownsville is known as "The Neck", and for years this flat stretch of land between the Intercounty and Lane Bane Bridges along Market Street was home to many professional businesses, banks, stores and shops, and more.  However, "The Neck" today is a skeleton of what it once was.  Many of the historic buildings with intricate architectural detail are boarded up and have been empty for many years.  Over the years, many proposals have come and gone to revitalize the city.  From riverboat gambling to pushing for the completion of the Mon-Fayette Expressway, Brownsville's residents and leaders hope to return the city to its former glory.

Dunlap's Creek Bridge:

At the bottom of "The Neck" sits, the first and oldest cast iron bridge built in the United States.  Dedicated on July 4, 1839, this 80 foot bridge over Dunlap's Creek was built and designed by Captain Richard Delafield of the US Army Corps of Engineers.  Built by the US Government to stabilize the crossing that had seen three bridges destroyed since 1801, the bridge's cost was $39,811.63. (1)  This was one of the last major projects undertaken by the federal government before turning over control of the National Road to the states.  The bridge consists of "five parallel arches, each consisting of nine segments." (1)  Later as the canal and then the rail eras began to shape the nation, the bridge would sit virtually unused to heavy traffic until the automobile age.

Over the bridge's nearly 200 year old history, there have been many changes within Brownsville and the structures in its immediate vicinity.  As Brownsville grew with the spread of the coal and steel industries, many structures were built over Dunlap's Creek and were tied into the bridge.  This would make the bridge appear much shorter in length than it actually is.   In addition, the Dunlap's Creek Bridge has received numerous recognition and awards.  Beginning with its dedication as a National Historic Landmark in 1920, this old bridge has accumulated five historical and engineering awards.  Plaques have been placed on the very detailed railings touting the structure's accomplishments.

A great example of how some of the buildings along "The Neck" surround the bridge. (Bruce Cridlebaugh)

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

By
Petroleum Club Road is an approximately 5.3-mile rural highway located in the Sunset Oil Field of western Kern County.  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.  In 1938 the West Side Highway was constructed west of Lakeview Gusher and still serves as the current alignment of California State Route 33.   Part 1; the history of Petroleum Club Road Petroleum Club Road is the original highway which linked the oil communities of Maricopa and Taft.  Both cities were developed around the early boom of the Sunset Oil Field.  The early Sunset Oil Field can be seen centered along Cienega Canyon Road southwest of Buena Vista Lake in Township 11 North, Range 23 West on the 1898 Kern County Surveyors map .  In 1901 Post Office Service would be established at the Su...

Hawaii Route 50

By
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.  A compellation of all Hawaii-related media from both Gribblenation and RoadwayWiz can be found by clicking  here .  Part 1; the history of Hawaii Route 50 and Kaumualii Highway Hawaii Route 50 is the longest highway on Kauai at 32.6 miles.  The highway begins at Rice Str...

Did Caltrans just kill the G26 cutout US Route shields?

By
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.   ...
