The New Youngs Bay Bridge is a vertical-lift bridge over Youngs Bay on U.S. Route 101 (US 101) between Astoria and Warrenton. Including the approaches, it is {{convert|4200|ft|m|adj=off}} long and was completed in 1964.{{cite web | url=http://bridgehunter.com/or/clatsop/830600900491/ | publisher=Bridgehunter | title=Youngs Bay Bridge (New) }} The road bridge had been proposed since 1948 and was approved by the state government in the late 1950s.{{cite news |date=March 1, 1958 |title=Board Okays Federal Road Link Provided Umatilla Bridge Used |page=6 |work=The Oregonian}} The routing across Youngs Bay for US 101 was chosen in 1955 over a more inland alignment that would have avoided the bay entirely.{{cite news |date=July 1, 1955 |title=Commission Picks Smith Point Route for Seaside-Astoria 101, Allots Nyssa Span Cash |page=26 |work=The Oregonian}} Construction began in March 1963 and was dedicated on August 29, 1964.{{cite news |date=August 31, 1964 |title=It's Shorter Over Youngs Bay Now |page=1 |work=The Oregonian}}

The bridge was built to the west of, closely in parallel to, a {{convert|1.6|mi|km|adj=on}} railroad trestle which also crossed the bay. It was built in 1896 for the Astoria and Columbia River Railway Company. The New Youngs Bay Bridge passed over the top of the railway bridge near the north river bank. The railroad bridge was used for the last time in 1982 and was dismantled in 1986.{{cite news|title=Trestle removal accents demise of railroad line|newspaper=The Oregonian|edition=Willamette Valley|agency=Associated Press|date=December 10, 1986|page=C14}}
