History
According to Citypopulationreview, US 730 was created in 1926. The road was paved in the early 1930s. The route originally began in Umatilla but was extended west to Boardman in 1942 and shortened to new I-84 east of Boardman in 1966. US 730 largely follows the former route of US 30, which in the past passed through Umatilla to Hermiston and Pendleton. A more direct route to Pendleton was built in the 1940s and later became part of I-84. This allowed the US 730 to be extended over the former US 30 from Umatilla to Boardman.
Traffic intensities
Every day, 3,100 vehicles drive at Boardman and 9,400 vehicles through Umatilla. 2,400 vehicles continue to Wallula.

The Astoria-Megler Bridge is a truss bridge in the United States, located on the border of the states of Oregon and Washington, near the city of Astoria. The bridge spans the Columbia River and is over 4 miles long.
Characteristics
The bridge spans the mouth of the Columbia River and is the westernmost bridge over this river. The Columbia River is North America’s largest river flowing into the Pacific Ocean. The bridge is a steel truss bridge with a cantilever main span on the Astoria side. The bridge connects Astoria in Oregon to the hamlet of Megler in Washington. Most of the bridge is located in the state of Oregon, as the border between the states is on the north side of the Columbia River.
The bridge is 6,545 meters long and has a main span of 376 meters, near Astoria. The clearance height is 60 meters in the main span, lower elsewhere. On the Washington side are another 7 larger spans. The bridge has 171 bridge piers standing in the water and 7 + 1 spans of the main bridges and 33 spans of the abutments and intermediate bridge sections. Over the bridge runs US 101 in Oregon with 2 lanes. The bridge deck is 8.5 meters wide. The bridge is managed by the Oregon State Department of Transportation. Traffic and cyclists pass over the bridge, but no pedestrians. The bridge is toll-free.
History
In 1926 a ferry service was established between Astoria and Megler. Since the through traffic mainly went inland through the Willamette Valley ( Interstate 5 in Oregon ), a bridge was built relatively late. The bridge was built between 1962 and 1966. The bridge opened to traffic on August 27, 1966. Construction cost $24 million at the time. The construction costs were recovered through tolls. The bridge became toll-free in 1993. The bridge was the last section of US 101 to be built.
Traffic intensities
7,300 vehicles cross the bridge every day. The nearest alternative bridge is at Longview, more than 50 miles upstream.

The Fremont Bridge is a double-deck arch bridge in the United States, located in Portland, Oregon. The bridge is part of Interstate 405 in Oregon.
Characteristics
The Fremont Bridge spans the Willamette River on the north side of Downtown Portland. The main bridge is 656.5 meters long with a main span of 382.5 meters, but the connecting road sections run over bridges. The arch is 116 meters high and the bridge deck is 53 meters above the river. The bridge is double-deck, with 4 lanes each and both left and right emergency lanes. The bridge is therefore spaciously designed compared to other bridges in and around Portland. Interstate 405 in Oregon runs across the bridge as a bypass of Downtown Portland. North of the bridge is an interchange with Interstate 5, south of it an interchange with US 30.
History
The 1966 Marquam Bridge of I-5 proved to be unpopular with the public, so a more architecturally valuable bridge was chosen. The old Port Mann Bridge in Vancouver, Canada served as an example. The bridge was subsequently constructed between 1970 and 1973 and opened to traffic on November 15, 1973. After opening, it was the longest arch bridge of this type for a long time, until the Caiyuanba Bridge opened in 2007 in Chongqing, China.
The bridge is named after John C. Frémont (1813-1890) who was one of the first white people to explore the Oregon region. He was also a general in the United States Army and unsuccessfully ran in the 1856 presidential election.
Traffic intensities
123,000 vehicles cross the bridge every day. The bridge itself has sufficient capacity, but the connecting nodes are a bottleneck.
