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

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.

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.

The history of US Route 80 and Interstate 8 in California

The historic corridor of US Route 80 and Interstate 8 through the borderlands of southern California share a largely mutual history.  Both highways originated in the city of San Diego and departed the state at the Colorado River into Yuma, Arizona.  Both highways share numerous famous geographical components such as the Mountain Springs Grade and Algodones Sand Dunes.  This article serves as a comprehensive history of the combined US Route 80/Interstate 8 corridor in California from the tolled stage route era of the nineteenth century to the development of the modern freeway.   The blog cover photo features US Route 80 along the Mountains Springs Grade through In-Ko-Pah Gorge during late 1920s.  This photo is part of the Caltrans McCurry Collection.

The Central Freeway of San Francisco (US Route 101)

The Central Freeway is a 1.2-mile elevated limited access corridor in the city of San Francisco.  As presently configured the Central Freeway connects from the end of the Bayshore Freeway to Market Street.  The Central Freeway carries the mainline of northbound US Route 101 from the Bayshore Freeway to Mission Street. The Central Freeway has origins with the establishment of Legislative Route Number 223 and is heavily tied to the history of the once proposed Panhandle Freeway.  The Central Freeway between the Bayshore Freeway and Mission Street was completed during 1955.  The corridor was extended to a one-way couplet located at Turk Street and Golden Gate Avenue in 1959 which served to connect US Route 101 to Van Ness Avenue.  The Central Freeway was damaged by the 1989 Loma Prieta Earthquake and has since been truncated to Market Street.   The Central Freeway as pictured on the blog cover was featured in the May/June 1959 California Highways & Public Works.  The scan below is fro

The Bayshore Freeway (US Route 101)

The Bayshore Freeway is a 56.4-mile component of US Route 101 located in the San Francisco Bay Area.  The Bayshore Freeway connects the southern extent of San Jose to the Central Freeway in the city of San Francisco.  The corridor was originally developed as the Bayshore Highway between 1923 and 1937.  The Bayshore Highway would serve briefly as mainline US Route 101 before being reassigned as US Route 101 Bypass in 1938.  Conceptually the designs for the Bayshore Freeway originated in 1940 but construction would be delayed until 1947.  The Bayshore Freeway was completed by 1962 and became mainline US Route 101 during June 1963.   Part 1; the history of the Bayshore Freeway Prior the creation of the Bayshore Highway corridor the most commonly used highway between San Jose and San Francisco was El Camino Real (alternatively known as Peninsula Highway).  The  American El Camino Real  began as an early example of a signed as an Auto Trail starting in 1906.  The era of State Highway Mainte
