Public Roads Administration Sites

In February 1936, to complete the portion of Highway 101 between Cannon Beach and Manzanita, the Oregon Highway Department approved construction plans for a 1227-foot-long tunnel through Arch Cape. The federal Public Roads Administration provided critical funding for the project. At the time of its construction, it was the longest tunnel on the Oregon Coast Highway. Difficulties associated with the long bore through both the cape's sandstone and basalt stretched the construction project out over almost four years. The presence of soft sandstone required the construction of a timber lining to prevent a cave-in. Construction workers struggled with difficult conditions including exposure...

Among the challenges in constructing the final link in Oregon's Highway 101, the state's bridge engineer responded by designing Chasm Bridge on Neahkahnie Mountain. Using Bureau of Public Roads funds and design advice from the National Parks Service, workers completed the bridge in 1937. An information plague located at a viewpoint on Neahkahnie Mountain describes the project, writing: "Built on the sheer face of Neahkahnie Mountain, this 59-foot reinforced concrete deck girder is a major engineering feat! Designed by Glenn S. Paxton, the bridge features stone masonry on its face and railings, which extend nearly uninterrupted around the mountain." Chasm Bridge is also...

The Pentagon is America’s Department of Defense headquarters and the largest office building in the world.  It was constructed from August 1941 to January 1943 in order to centralize the administration of the U.S. armed services during World War II.   The site of the Pentagon had previously been a barren area, so the Public Roads Administration, a division of the New Deal’s Federal Works Agency (FWA), supervised a “$7 million network of highways to serve the and adjacent areas” (Sunday Star, 1942). While it may not appear to be a typical New Deal public works project, the Pentagon was built...

New Deal agencies realigned and reconstructed 47 miles of the Tioga road from Crane Flat to Tioga Pass over the years 1933 to 1943.  They were not able, however, to complete the road down from Tioga Pass to Lee Vining (Mono Lake), which remained in deplorable condition until it was remade in 1961.  Funding for the Tioga Road project came from the Public Works Administration (PWA); the Bureau of Public Roads (BPR) managed construction, using private companies; and the Civilian Conservation Corps (CCC) did auxiliary work landscaping roadsides. The National Park Service (NPS) oversaw all work in the park.  The short-lived...
