The Old Youngs Bay Bridge is a bascule bridge across Youngs Bay in Astoria , Oregon completed in 1921 . Conde McCullough was responsible for designing this bridge , his first for Oregon . The bridge consists of two 75-foot ( 23 m ) steel bascule leaves approached over a pile trestle and timber spans . It has a total length of 1,766 feet ( 538 m ) . The bridge features early versions of McCullough 's signature accent elements , with Art Moderne concrete pylons topped by light fixtures flanking the landings at either end of the bridge .
Astoria is a port city and the seat of Clatsop County , Oregon , United States . Founded in 1811 , Astoria is the oldest city in the state of Oregon and was the first American settlement west of the Rocky Mountains . Astoria is located on the south shore of the Columbia River , where the river meets the Pacific Ocean . The city is named for John Jacob Astor , an investor from New York City whose American Fur Company founded Fort Astoria at the site . Astoria was incorporated by the Oregon Legislative Assembly on October 20 , 1876 . The city is served by the deepwater Port of Astoria . Transportation includes the Astoria Regional Airport with U.S. Route 30 and U.S. Route 101 as the main highways , and the 4.1-mile ( 6.6 km ) Astoria-Megler Bridge connecting to neighboring Washington across the river . The population was 9,477 at the 2010 census .
U.S. Route 101 ( US 101 ) , is a major north-south U.S. Highway in Oregon that runs through the state along the coastline near the Pacific Ocean . It runs from the California border , south of Brookings , to the Washington state line on the Columbia River , between Astoria , Oregon , and Megler , Washington . US 101 is designated as the Oregon Coast Highway No . 9 ( see Oregon highways and routes ) , as it serves the Oregon Coast region . Much of the highway runs between the Pacific Ocean and the Oregon Coast Range , thus US 101 is frequently mountainous in character . For most of its length it is a two-lane undivided highway . Many parts of the highway are subject to closure due to landslides caused by excessive rainfall , and in many parts of the coast , US 101 is the only viable route connecting certain coastal communities . Thus , in many cases when landslides block US 101 , the detour requires traveling inland over the Coast Range to alternative north-south routes in the Willamette Valley and then back west over the Coast Range again . US 101 is often the main street through coastal towns in Oregon , which can cause significant traffic delays . This is especially true in Lincoln City , where geography and tourism combine to create traffic problems .
The Oregon City Bridge , also known as the Arch Bridge , is a steel through arch bridge spanning the Willamette River between Oregon City and West Linn , Oregon , United States . Completed in 1922 , it is listed on the National Register of Historic Places . It was built and is owned by the Oregon Department of Transportation ( ODOT ) as part of Oregon Route 43 and is the third-southernmost Willamette bridge in the Portland metropolitan area , after the Boone Bridge in Wilsonville and the Oregon 219 bridge near Newberg . The bridge is 745 ft ( 227 m ) in length and 28 ft ( 8½ m ) wide with a 360 ft ( 110 m ) long main span that provides 49 ft ( 15 m ) of vertical clearance at low river levels . The narrow width causes problems for large vehicles that cross it , often requiring traffic going in the other direction to stop . TriMet buses ceased using the bridge in 2009 . This bridge is the only Oregon bridge to be encased in gunite , which protects it from corrosive sulfur dioxide emissions from paper mills south of the bridge . The concrete look was favored by bridge designer Conde McCullough , designer of 500 Oregon bridges . His signature detailing is evident in the obelisk pylons with sconced light fixtures , ornate railings , and Art Deco piers . The Oregon City Bridge is just downstream from the 40 ft ( 12 m ) tall Willamette Falls and the Willamette Falls Locks , the oldest navigational locks in the United States . Downstream from this bridge is the George Abernethy Bridge , which carries Interstate 205 .
Oregon City is the county seat of Clackamas County , Oregon , United States , located on the Willamette River near the southern limits of the Portland metropolitan area . Established in 1829 by the Hudson 's Bay Company , in 1844 it became the first U.S. city west of the Rocky Mountains to be incorporated . As of the 2010 census , the city population was 31,859 .
Oregon Route 43 is an Oregon state highway that runs between the cities of Oregon City and Portland , mostly along the western flank of the Willamette River . While it is technically known by the Oregon Department of Transportation as the Oswego Highway No . 3 ( see Oregon highways and routes ) , on maps it is referred to by its route number or by the various street names it has been given .
Rowena is an unincorporated community in Wasco County , Oregon , United States . For statistical purposes , the United States Census Bureau has defined Rowena as a census-designated place ( CDP ) . The census definition of the area may not precisely correspond to local understanding of the area with the same name . The population was 187 at the 2010 census . Rowena is located west of The Dalles on the Columbia River , where the river passes through the natural feature Rowena Gap . Interstate 84 ( Columbia River Highway ) and U.S. Route 30 ( Historic Columbia River Highway ) pass through the community . Route 30 near Rowena is notable for the Rowena Loops . The origin of the name Rowena is disputed . Two sources say Rowena was named for H.S . Rowe , a railroad company official , in the early 1880s . Another source says it was named for a girl , Rowena , who had been living in the area at the time the community was founded . It is also possible that the name comes indirectly from Rowena , Ivanhoe 's lover in the novel of the same name by Sir Walter Scott .
U.S. Route 30 or U.S. Highway 30 ( US 30 ) is an east-west main route in the system of the United States Numbered Highways , with the highway traveling across the northern tier of the country . With a length of 3,073 miles ( 4,946 km ) , it is the third longest U.S. highway , after U.S. Route 20 and U.S. Route 6 . The western end of the highway is at US 101 in Astoria , Oregon ; the eastern end is at Virginia Avenue , Absecon Boulevard , and Adriatic Avenue in Atlantic City , New Jersey . Despite long stretches of parallel and concurrent Interstate Highways , it has not been decommissioned unlike other long haul routes such as U.S. Route 66 . The 0 as the last number in the digit indicates that it is a coast-to-coast route and a major east-west route . Much of the historic Lincoln Highway , the first road across America ( from New York City to San Francisco ) , became part of US 30 ; it is still known by that name in many areas . US 30 and US 20 break the general U.S. Route numbering guidelines in Oregon , since US 20 actually starts south of US 30 in Newport , Oregon and US 30 runs parallel to the north throughout the state ( the Columbia River and Interstate 84 ) . The two run concurrently and continue in the correct positioning near Caldwell , Idaho . This is because US 20 was not a planned coast-to-coast route while US 30 was . US 20 originally ended at the eastern entrance of Yellowstone National Park ; it was extended in 1940 .
Winchester is an unincorporated community in Douglas County , Oregon , United States . It is 4 miles ( 6.4 km ) north of Roseburg on Interstate 5 and the North Umpqua River .
Oregon Route 99 is a state highway that runs between the southern border of Oregon , and the city of Junction City . Oregon Route 99 was formed from parts of the former U.S. Route 99 ; it shares much of its route with Interstate 5 , but much of it is also independent . Between Portland and Junction City , the highway is forked into two routes : Oregon Route 99E and Oregon Route 99W .
The Lewis and Clark River Bridge is a bascule bridge that spans the Lewis and Clark River on U.S. Route 101 Business ( a section originally part of U.S. Route 101 ) in Clatsop County , Oregon . It was designed by Conde McCullough and opened in 1925 . It was built to replace an earlier bridge at the same location , a swing-span bridge constructed around 1910 . The total length of the bridge is 828 feet ( 252 m ) , and the length of the bascule main span is 112 ft ( 34 m ) . The approach spans consist of a total of 48 timber pile and stringer spans .
Perry is an unincorporated community in Union County , Oregon , United States . It is located five miles west of La Grande on the Grande Ronde River and Interstate 84 . The town was originally named Stumptown , but was later renamed in honor of an early railroad dispatcher in La Grande . Perry is located at 45°20′53″N 118°10′01″W / 45.348°N 118.167°W / 45.348 ; -118.167Coordinates : 45°20′53″N 118°10′01″W / 45.348°N 118.167°W / 45.348 ; -118.167 and has an elevation of 2987 feet ( 883 meters ) . Perry came into existence in 1890 , when the Smith-Stanley Lumber Company built a sawmill in the area . A post office was established in the same year . The mill was sold to Charley and Jim Mimnaugh and again in 1900 to C.W . Nibley and George Stoddard , who renamed the mill he Grande Ronde Lumber Company . In 1927 , the Grande Ronde Lumber Company merged with the Stoddard Lumber Company of Baker City and moved across the valley to Pondosa , taking most of the town with it . The post office was discontinued in 1931 .
The Ellsworth Street Bridge is a highway bridge that crosses the Willamette River in Albany , Oregon , United States . Built in 1925 , the two-lane structure carries U.S. Route 20 eastbound traffic , with the adjacent Lyon Street Bridge carrying westbound traffic . The 1,090-foot ( 330 m ) -long steel-truss bridge was designed by Conde McCullough and opened in 1926 .
Albany is the county seat of Linn County , and the 11th largest city in the State of Oregon . Albany is located in the Willamette Valley at the confluence of the Calapooia River and the Willamette River in both Linn and Benton counties , just east of Corvallis and south of Salem . It is predominantly a farming and manufacturing city that settlers founded around 1848 . As of the 2010 United States Census , the population of Albany was 50,158 . Its population was estimated by the Portland Research Center to be 54,453 in 2018 . Albany has a home rule charter , a council-manager government , and a full-time unelected city manager . The city provides the population with access to over 30 parks and trails , a senior center , and many cultural events such as the Northwest Art & Air Festival , River Rhythms and Movies at Monteith . In addition to farming and manufacturing , the city 's economy depends on retail trade , health care , and social assistance . In recent years the city has worked to revive the downtown shopping area , with help from the Central Albany Revitalization Area .
U.S. Route 20 ( US 20 ) is a major west-east cross-state highway in the northern part of the U.S. state of Oregon , especially east of the Cascade Mountains . It connects U.S. Route 101 in Newport on the central Oregon Coast to the Idaho state line east of Nyssa .
Rocky Creek Bridge No . 01089 , also known as Ben Jones Bridge , is a concrete highway bridge spanning Rocky Creek along the Pacific Ocean coast of the U.S. state of Oregon . The bridge crosses a gorge near the creek 's mouth , about 2 miles ( 3 km ) south of Depoe Bay in Lincoln County . Built in 1927 , the bridge originally carried U.S. Route 101 ( the Oregon Coast Highway ) over the creek . After a stretch of the highway was relocated to make it straighter , the abandoned piece of the old highway became Otter Crest Loop Road , a bypass west of the new highway . Designed by Conde McCullough , the arch bridge is 360 feet ( 110 m ) long . McCullough , the state bridge engineer from 1919 to 1936 , designed many bridges along the Oregon Coast Highway , which extended north-south from Washington to California . Jones was a lawyer who helped establish Lincoln County in 1893 , who served as mayor of the Oregon cities of Toledo and Newport , and who introduced legislation at the state level that led to construction of the coast highway . The Oregon Department of Transportation repaired and reconstructed parts of the deteriorating bridge in 2001 and added safety features . The Oregon State Historic Preservation Office assisted with the project , and the bridge was added to the National Register of Historic Places in 2005 .
Lincoln County is a county located in the U.S. state of Oregon . As of the 2010 census , its population was 46,034 . The county seat is Newport . The county is named for Abraham Lincoln , 16th president of the United States . Lincoln County comprises the Newport , OR Micropolitan Statistical Area .
The Depoe Bay Bridge is one of a series of significant bridges along the Oregon Coast Highway . The concrete arch bridge spans the mouth of Depoe Bay at milepost 127.61 with a 150-foot ( 46 m ) main span , and a total length of 312 feet ( 95 m ) . The bridge 's designer was Conde McCullough who designed all of the 1920s bridges on the highway . The original bridge , completed in 1927 , was only 18 feet ( 5.5 m ) wide from curb to curb with no sidewalks , and was widened in 1940 with a similar arched concrete bridge immediately adjacent to the original . The added structure is sympathetic to the original and is included in the National Register of Historic Places listing .
Depoe Bay is a city in Lincoln County , Oregon , United States , located on U.S. Route 101 next to the Pacific Ocean . The population was 1,398 at the 2010 census . The bay of the same name is a 6-acre ( 2.4 ha ) harbor that the city promotes as the world 's smallest navigable harbor . [ a ]
The Crooked River High Bridge is a steel arch bridge that spans the Crooked River gorge in Jefferson County , Oregon . The bridge was designed by Conde McCullough and was completed in 1926 . Shortly after its completion , Oregon State Highway Division created the Peter Skene Ogden Park just to the south of the bridge . The bridge has a total length of 464 feet ( 141 m ) with a main span of 330 feet ( 100 m ) . The deck is 295 feet ( 90 m ) above the canyon floor . The bridge was eventually unable to keep up with the growing traffic demands of US 97 ( US 97 ) , and was replaced by the wider Rex T. Barber Veterans Memorial Bridge . The old bridge is open to pedestrians .
Jefferson County is a county located in the U.S. state of Oregon . As of the 2010 census , the population was 21,720 . The county seat is Madras . The county is named after Mount Jefferson .
U.S. Route 97 ( US 97 ) in the U.S. state of Oregon is a major north-south United States highway which runs from the California border , south of Klamath Falls , to the Washington border on the Columbia River , between Biggs Junction , Oregon and Maryhill , Washington . Other than the northernmost stretch ( which is known as the Sherman Highway ) , US 97 ( along with US 197 ) is known as The Dalles-California Highway . In May 2009 , Oregon Senate passed a bill to rename US 97 as World War II Veterans Historic Highway . With the exception of Interstate 5 ( I-5 ) , US 97 is the most important north-south highway corridor in the state . It serves two major population centers ( Klamath Falls and Bend ) , and is the main corridor east of the Cascade Mountains . While much of the highway remains in two-lane undivided configuration , significant sections have been upgraded to expressway or freeway status .
The Big Creek Bridge is a bowstring arch bridge that spans the Big Creek on U.S. Route 101 in Lane County , Oregon . It was designed by Conde McCullough and opened in 1931 . The bridge has a total length of 180 ft ( 55 m ) and contains one 120 ft ( 37 m ) reinforced concrete tied arch , identical in design to Ten Mile Creek Bridge and Wilson River Bridge . The locations for all three bridges were similar in that the sandy foundations were not secure enough for the abutment piers required to relieve the lateral pressure of traditional arches . The flood levels of the rivers approached the road grade and ruled out the use of reinforced concrete girders . The corrosive salt air eliminated the practicality of steel truss bridges . The design of the bridge was similar to the rainbow arch design patented by James Barney Marsh . The bridge , along with the Ten Mile Creek Bridge and the Wilson River Bridge , was rehabilitated in 1996 to increase the overhead clearance and add a cathodic protection system to protect the embedded steel reinforcements against the corrosive air . A project to replace the cathodic protection system began in February 2014 .
Lane County is a county in the U.S. state of Oregon . As of the 2010 census , the population was 351,715 , making it the fourth-most populous county in Oregon . The county seat is Eugene .

Ten Mile Creek Bridge ( No . 01181 ) is a Conde McCullough-designed bridge near Yachats in Lane County in the U.S. state of Oregon . It was listed on the National Register of Historic Places in 2005 . The bridge carries U.S. Route 101 over Tenmile Creek . McCullough designed the structure in 1931 . Built of reinforced concrete through a tied arch , the total length of the bridge is 180 feet ( 55 m ) with a main span of 120 feet ( 37 m ) . Ornate precast concrete railings run along the sides .
Yachats ( /ˈjɑːhɑːts/ YAH-hahts ) is a small coastal city in Lincoln County , Oregon , United States . According to Oregon Geographic Names , the name comes from the Siletz language and means dark water at the foot of the mountain . There is a range of differing etymologies , however . William Bright says the name comes from the Alsea placename yáx̣ayky ( IPA : /ˈjaχajkʲ/ ) . At the 2010 census , the city 's population was 690 . In 2007 , Budget Travel magazine named Yachats one of the Ten Coolest Small Towns of the U.S.A. , and Yachats was chosen among the top 10 U.S. up-and-coming vacation destinations by Virtualtourist . In 2011 , Arthur Frommer , founder of Frommer 's Travel Guides , listed Yachats number seven among his ten favorite vacation destinations in the world . [ citation needed ]

Oregon Route 99E is an Oregon state highway that runs between Junction City , Oregon and an interchange with I-5 just south of the Oregon/Washington border , in Portland . It , along with OR 99W , makes up a split of OR 99 in the northern part of the state . This split existed when the route was U.S. Route 99 , when the two branches were U.S. 99W and U.S. 99E . ( Another such split occurred in California , but with the decommissioning of U.S. 99 , that state elected to rename its U.S. 99W as Interstate 5 , rather than preserve the directional suffix . ) Currently , OR 99E and OR 99W do not reconvene at a northern junction in Oregon ; OR 99W has been truncated from its original route , and ends in Downtown Portland , several miles south of its original northern terminus ; nor is OR 99 ( without a suffix ) signed anywhere in Portland .
The Umpqua River Bridge is a swing-span bridge that spans the Umpqua River in Reedsport , Oregon . It consists of a central swing span flanked by two reinforced concrete arches on each end .
