"This photograph was taken from the east end of the Tooth Rock Tunnel on U.S. Highway 30, the Columbia River Highway in Multnomah County. This photograph shows the stone arch at the entrance of the tunnel and looks down the highway toward the Eagle Creek Bridge and a railroad bridge. Forested hills line both sides of the highway."

The Eagle Creek Bridge was constructed in 1936 as part of a realignment project on the Historic Columbia River Highway (US 30). The project was built to straighten a notoriously crooked and narrow stretch of the highway around Tooth Rock.
The previous alignment was carved out of the shear basalt cliffs of Tooth Rock and passed over two ravines via the Tooth Rock and Eagle Creek Viaducts. This narrow section of roadway was a mere 18-feet wide and thus needed to be widened to accommodate the larger vehicles being manufactured.
As part of the realignment the Tooth Rock Tunnel was blasted through Tooth Rock and created a need for a new bridge over Eagle Creek. The Oregon State Highway Department engineers under State Bride Engineer Conde B. McCullough designed an elegant three span steel tied arch bridge to accommodate the need. The design was similar to other steel tied arch bridges built during this era, such as the Winston Bridge over the South Umpqua River near Winston and the McLoughlin Bridge over the Clackamas River near Oregon City.
By 1969 the interstate era was upon the Columbia River Gorge and the 1936 Eagle Creek Bridge was replaced with a wider three span steel plate girder bridge. The new bridge uses the original 1936 piers, but the arches were removed to make way for the plate girders.
In 1970 the main 180-foot center span of the Eagle Creek Bridge was re-erected near Barton, Oregon in Clackamas County as part of the Barton Bridge on Bakers Ferry Road. The Barton Bridge was not constructed with the architectural treatments of the Eagle Creek Bridge, but still has some of the charm of an old tied arch bridge.

Design
The Eagle Creek Bridge was a three span steel tied arch. The three spans measured 142-feet, 180-feet, and 142-feet. The bridge featured many of the design details utilized by State Bridge Engineer Conde B. McCullough, such as arched steel portal frames and architectural railing. The design is very similar to the Winston Bridge in Douglas County.

This span was previously built over Eagle Creek along the Columbia River in 1926, moved here in 1970. The move is mentioned in the Eagle Creek file but I do not see it here. I remember the previous bridge over the Clackamas with the rattling plank deck.
