The road begins in western Eugene at an intersection with State Route 126. The road heads north with 1×2 lanes and then becomes a 2×2 lane freeway that runs along the north side of Eugene. There is an interchange with the Delta Highway, after which the road ends at an interchange with Interstate 5.

The highway was built by Lane County in the 1960s. This is special, because few highways in the United States have been built through the counties. It has been a State Route administered by the State of Oregon since 1978, when it was numbered State Route 69. In 2007 the road was renumbered to State Route 569 because the road number plates were stolen.
37,000 vehicles drive daily on the north-south section on the west side of Eugene and 52,000 to 78,000 vehicles on the northern section. In 2010, State Route 569 was Eugene’s busiest highway.

The Interstate Bridge is a truss bridge and lift bridge in the United States, located on the border of the states of Oregon and Washington. The bridge spans the Columbia River in Portland and is part of Interstate 5.
The Interstate Bridge actually consists of two parallel bridges with an identical appearance. The bridge measures 1,078 meters in total and is a steel truss bridge, whose main span is 162 meters wide. On the north side is a lift bridge for large ships. The lifting section is 70 meters high, the maximum passage when open is 54 meters. The maximum vertical clearance of the fixed bridge is 22 meters. Both bridges are 12 meters wide, with 3 lanes without emergency lanes. Interstate 5 runs across the bridge, connecting Portland in the south to Vancouver in the north. The bridge is toll-free.

The Interstate Bridge predates the Interstate Highway system and is one of the oldest, if not the oldest bridge still part of an Interstate Highway today. The first bridge was built in two years between 1915 and 1917 and opened to traffic on February 14, 1917. Construction cost $1.75 million at the time. At the time, the bridge had a carriageway of 11.6 meters wide and a footpath of 1.5 meters wide. It was the second bridge over the Columbia River and the first to straddle the Oregon-Washington border. Trams ran over the bridge between opening in 1917 and 1940. The bridge was a toll road between 1917 and 1928.
In 1957 the bridge became part of Interstate 5. A second parallel span of comparable dimensions has been constructed for this purpose. It opened to traffic in 1958 and cost $14.5 million. Subsequently, the old bridge was renovated and jacked up to increase the vertical clearance of the main span. From 1960 the full capacity of 2×3 lanes was available. The bridge was then briefly a toll road until 1966.
Over the years, adjustments and upgrades have been made to the bridge, especially to the lifting part. The bridge deck was renovated in 1995.

The Interstate Bridge is believed to be the oldest bridge in the Interstate Highway system. It is planned to replace the aging bridge, this project is called the Columbia River Crossing, or CRC. Both bridges are what is called “functionally obsolete”, meaning that they do not meet current design requirements. About 400 collisions occur on the bridge every year. Despite this, the bridges are not in particularly bad condition, but the earthquake resistance of the bridges is being questioned.
The high cost of the replacement and the general anti-automotive policy of the City of Portland, and anti-public transit sentiment on the part of Washington State have caused the project to continue to slow down. In addition, Washington state has little interest in sharing the costs. There are plans to build a light rail over the bridge. In any case, the new bridge will be a toll roadto recoup construction costs. The construction cost of the bridge is estimated at approximately $2 billion, plus $600 million in alterations to Interstate 5 in Oregon and $430 million in Washington, with the total cost being between $3 and 3.5 billion. It is estimated that half of this will be recovered through tolls. The project was “finally” scrapped in March 2014 after incurring $105 million in planning costs. However, it was expected that the project will be restarted in due course because the bridges are old.
On March 6, 2017, a bill was passed in the Washington State House of Representatives to revive the project. In 2019, the Oregon Governor also expressed support for the bridge’s replacement. In November 2019, the replacement of the bridge seemed to become more concrete. In May 2022, a new plan for a 2×4 lane bridge was presented.
In 2012, 124,000 vehicles crossed the bridge every day, which means it is at its maximum capacity.
