Pengra Covered Bridge - Oregon

Image
By

 


Also known as the Fall Creek Covered Bridge, the Pengra Covered Bridge is a 268 foot long covered Howe through truss designed covered bridge spanning over the Fall Creek in Lane County, Oregon, southeast of Eugene and Springfield. Built in 1938, the bridge was built by A.C. Striker, who was the Lane County bridge superintendent at the time. The Pengra Covered Bridge contains two of the longest timbers ever cut for a bridge in Oregon, covered or not. The timbers for the lower chords, 16 inch by 18 inch by 126 feet long. Since 18 inch timbers were too large to be run through a sawmill, they were rough hewn in the woods, transported to the bridge site by truck and resurfaced before being set into place. The dimensions of the upper chord are of similar proportions at 14 inch by 18 inch by 96 feet long. While the use of one piece chords simplified construction techniques in building the bridge and resulted in a stronger truss, the handling such large timbers often proved to be difficult. Another distinctive feature of the bridge is a small roofed window on the southwest facing side, allowing drivers to see oncoming traffic as it approaches the bridge.

The Pengra Covered Bridge replaced a 192 foot span that was built in 1904 and was only a few feet upstream from the current bridge. The effect of weather and increased traffic caused Lane County to close the bridge in 1979. While Lane County officials had planned to reopen the structure, getting a contract ready for work for bridge restoration was delayed for several years. The bridge was repaired and reopened to traffic by Lane County in 1995 with the help of a grant from the Oregon Covered Bridge Program.

Regarding the name, Pengra was a station on the Cascade Line of the Southern Pacific Railroad and was named for B.J. Pengra, a pioneer in the history of early Oregon who later became general surveyor of Oregon in 1862. Pengra had surveyed the route of the Oregon Central Military Road to link the Willamette Valley with the Owyhee mining country of Eastern Oregon. The road was finished to the summit of the Cascades in 1867, but was seldom used, perhaps due to other roads that were built at the time (the Santiam Wagon Road along what is modern day US 20 comes to mind). The Pengra Unity Road lies on the old railroad grade of the old Cascade Line and has been renamed Place Road, but the bridge retains the name.

Grand Loop Road of Yellowstone National Park

By
  Grand Loop Road is a 140 mile loop highway which traverses the interior of Yellowstone National Park.  Grand Loop Road connects all of the major attractions and geological features of Yellowstone National Park along with the entrance roads.  Grand Loop Road is a seasonal highway and despite some conjecture never has been part of the US Route System.   Part 1; the history of Grand Loop Road The majority of history pertaining to Grand Loop Road was taken from the below National Park Service article: Historic Roads - Yellowstone National Park (U.S. National Park Service) (nps.gov) Yellowstone was declared the first National Park of the United States on March 1st, 1872.  The first real highway to access Yellowstone National Park came in 1873 when a tolled facility was constructed from Bozeman, Montana via Yankee Jim Canyon to Mammoth Hot Springs.  Numerous attempts were made to fund construction of roadway infrastructure during the early years of Yellows...

The last 1956-63 era California Sign State Route Spade?

By
Along southbound California State Route 170 (the Hollywood Freeway Extension) approaching the Hollywood Freeway/Ventura Freeway interchange a white California State Route 134 Sign State Route Spade can be observed on guide sign.  These white spades were specifically used during the 1956-63 era and have become increasingly rare.  This blog is intended to serve as a brief history of the Sign State Route Spade.  We also ask you as the reader, is this last 1956-63 era Sign State Route Spade or do you know of others?  Part 1; the history of the California Sign State Route Spade Prior to the Sign State Route System, the US Route System and the Auto Trails were the only highways in California signed with reassurance markers.  The creation of the US Route System by the American Association of State Highway Officials during November 1926 brought a system of standardized reassurance shields to major highways in California.  Early efforts to create a Sign State Route ...

California State Route 70; the Feather River Highway

By
From 2017 through to early 2019 I drove the majority of the California State Route 70; the Feather River Highway from CA 89 southwest to CA 99. CA 70 is an approximately 178.5 mile state highway which starts at US 395 near the Nevada State Line and travels west through the Feather River Canyon to CA 99.  CA 70 is often referred to as the Feather River Highway" given it's close association with the river.  Historically CA 70 was previously signed as US 40A and CA 24.  The Legislative Routes prior to the 1964 California Highway Renumbering that made up the current route of CA 70 are as follows: -  Legislative Route Number 21 from US 395 westward to Oroville. -  LRN 87 from Oroville south to Marysville. -  LRN 232 from Marysville to the current junction with CA 99.  CA 70 was even dual signed with CA 99 into Sacramento on what was LRN 232 for a time. The change from US 40A/LRN 21/LRN 87/LRN 232 can be seen by comparing the 1963 State Highway Ma...
