Siuslaw River Bridge - US 101 in Florence, Oregon

 


As the Oregon Coast Highway (US 101) was being completed across the State of Oregon during the 1930s, a number of bridges needed to be built to cross some of the state's finest rivers. In Florence, Oregon, the Siuslaw River Bridge was designed and constructed to help fill in the gaps between different coastal communities. Built in 1936, the Siuslaw River Bridge is a bascule bridge flanked by two reinforced concrete arches that spans across the Siuslaw River. The bridge and the river get their names from the Siuslaw tribal people who make their home along the river valleys of this part of the Oregon Coast. Today, the bridge provides a vital link connecting US 101 and the Central Oregon Coast to points north and south.

The total length of the Siuslaw River Bridge is 1,568 feet, stretching across the river. But more specifically, the bridge is made up of a north approach with eight spans of reinforced concrete deck girder totaling 478 feet in length. There is a main span in three parts, which includes a 140 foot long double leaf Chicago style bascule lift with single 154 foot reinforced concrete tied arch at each end of the bascule lift. Finally, there is a south approach with twelve spans of reinforced concrete deck girder totaling 646 feet in length. Staying true to the artistic touches that bridge engineer Conde McCullough liked to include in his bridge designs, there are four Art Deco style obelisks that house mechanical equipment as well as quarters and office space for the bridge operator were also included in the Siuslaw River Bridge's construction.

Designed by Oregon's State Bridge Engineer Conde B. McCullough, the Siuslaw River Bridge was built by the Mercer-Fraser Company of Eureka, California, and funded by the Federal Emergency Administration of Public Works (which was later renamed the Public Works Administration). With the New Deal programs that came about during the administration of President Franklin Delano Roosevelt’s New Deal Programs, such as the Civilian Conservation Corps (CCC) and the Public Works Administration (PWA), this helped to provide some of the jobs and lend some of the money construction so that the final gaps along the Oregon Coast Highway could be closed. With the funds secured, McCullough had the responsibility of designing, supervising, and finishing the construction of the five major bridges that were to span major bodies of water along the coast, including the Yaquina Bay Bridge in Newport and the Siuslaw River Bridge. With the inclusion of the funds provided for the Siuslaw River Bridge, the total cost of the bridge was $527,000.

The Siuslaw River Bridge can be enjoyed and seen from a number of vantage points along the Siuslaw River in Florence. For instance, there is a nice viewpoint of the bridge at the Siuslaw Interpretive Center, which is a small park just east of the bridge. In conclusion, the bridge is one of the many treasures you can discover during a trip along the Oregon Coast.

Cajon Pass; Cajon Pass Toll Road, National Old Trails Road, US Route 66/91/395 and Interstate 15

This past weekend I spent some time in Cajon Pass traversing the many historic road alignments. Cajon Pass is located in San Bernardino County, California along the San Andreas Fault.  Cajon Pass  serves the boundary line between the Mojave Desert, the San Gabriel Mountains, San Bernardino Mountains and San Bernardino Valley.  Cajon Pass is historically one of the most traveled transportation corridors in American California and presently is served by four rail lines, Interstate 15 and California State Route 138. While Cajon Pass is known mostly for carrying US Route 66 it has carried numerous other signed highways that have had a significant impact on regional and national road travel.  While this is my best attempt to compile everything from the best sources I could find into one single transportation history blog regarding road travel in Cajon Pass I suspect as time goes on this article will be frequently updated.  If you have any information that you ...

Pardee Dam Road

Pardee Dam is a 358-foot-high concrete structure located near Campo Seco at the Calaveras County and Amador County Line.  Pardee Dam impounds the Mokelumne River which forms the namesake Pardee Reservoir.  Pardee Dam was completed during 1929 and is part of the East Bay Municipal Utility District.  Pardee Dam is accessed by the namesake Pardee Dam Road which crosses the structure via the one-lane road seen as the blog cover photo.   Part 1; the history of Pardee Dam Road The closest community to Pardee Dam is that of Campo Seco on the Calaveras County side of the Mokelumne River.  Campo Seco was founded in 1850 by Mexican Miners who worked placer claims in Oregon Gulch during the height of the California Gold Rush.  Campo Seco would reach a population of about three hundred by 1860 spurred by the numerous mining claims in the area.  Main Street of Campo Seco flowed directly into the Campo Seco Turnpike which had been authorized by the California L...

California State Route 82/Old US Route 101 on the El Camino Real from San Francisco to Interstate 380

After completing Interstate 380 I made my way northward into the City Limits of San Francisco to drive the northernmost portion of California State Route 82. CA 82 is 52 mile State Route between I-280 in San Francisco southward to Interstate 880 in San Jose.  CA 82 is significant due to it being part of the historical surface alignment of US Route 101 and the El Camino Real. The "El Camino Real" was a Spanish Highway in Las Californias and Alta California which connected the 21 Catholic Missions along the coast.  Essentially the route of the El Camino Real was plotted out in the late 1700s from two Spanish survey expeditions.  The Missions were plotted approximately 30 miles apart along the 600 mile route so that they would be a single day journey by horse.  The El Camino Real name fell into disuse after the Mexican Revolution of 1821 but was revived by American highway promoters in the 1890s and 1900s.  Today the El Camino Real is mostly associated...
