"90° panorama of the Astoria-Megler Bridge and twilight-shrouded Astoria, Oregon. Looking southward from Point Ellice on the Washington side of the Columbia River. On the left, the Astoria Column is visible lit with holiday lights. Just right of the column is Saddle Mountain. In the center, between the piers of Astoria-Megler, lies the Young Bay Bridge, discernible by its overhead lights and the blur of traffic from U.S. Route 26. The sky displays hues of pink and purple in this early-December photo."

The Astoria–Megler Bridge is a steel cantilever through truss bridge that spans the Columbia River between Astoria, Oregon and Point Ellice near Megler, Washington, in the United States. Located 14 miles (23 km) from the mouth of the river, the bridge is 4.1 miles (6.6 km) long[3] and was the last completed segment of U.S. Route 101 between Olympia, Washington, and Los Angeles, California.[4] It is the longest continuous truss bridge in North America.
The bridge was built jointly by the Oregon Department of Transportation and Washington State Department of Transportation.[6]
Construction on the structure began on November 5, 1962. The concrete piers were cast at Tongue Point, 4 miles (6 km) upriver. The steel structure was built in segments at Vancouver, Washington, 90 miles (145 km) upriver, then barged downstream where hydraulic jacks lifted them into place. On August 27, 1966, with more than 30,000 people in attendance, Governors Mark Hatfield of Oregon and Dan Evans of Washington opened the bridge by cutting a ceremonial ribbon. The cost of the project was $24 million, equivalent to $174 million today,[7] and was paid for by tolls that were removed on December 24, 1993, more than two years early.[3]
The bridge is 21,474 feet (6,545 m) in length[8] and carries one lane of traffic in each direction. The main span is closest to the Oregon side and measures 1,232 feet (376 m) long.[5] The bridge was built to withstand 150 mph (240 km/h) wind gusts and river speeds of 9 mph (14 km/h).[4] As of 2004, an average of 7,100 vehicles per day use the Astoria–Megler Bridge.[9] Designed by William Adair Bugge (July 10, 1900 - November 14, 1992), construction of the cantilever truss bridge was completed by the DeLong Corporation, the American Bridge Company, and Pomeroy Gerwick.[10]
The south end is located at 46.18723°N 123.85427°W beside what used to be the toll plaza, at the end of a 650-metre (2,130 ft)[11] long inclined ramp which goes through a 360° loop while gaining elevation to clear the channel over land. The north end is at 46.24084°N 123.87493°W and connects directly to SR 401. Since most of the northern portion of the bridge is over non-navigable water, it is low to the water.

Normally, only motor vehicles and bicycles are allowed on the bridge—not pedestrians.[14][15] However, one day a year, usually in October (in 2012, it is on September 30), the bridge is host to the Great Columbia Crossing.[16][17] The event uses the 4.1 mile-long (6.6 kilometer) bridge to cross the river. The entire route is 10 kilometers (6.21 miles). Participants are taken by shuttle to the Washington side from where they run or walk to the Astoria side. Motor traffic is allowed to use only one lane (of two lanes) and is advised to expect delays during the two hour race.
