The connecting arch from US 30 to I-405 with a view of the Fremont Bridge.
On the south side of downtown, Interstate 5 splits, with I-5 on the east bank of the Willamette River, and I-405 on the west bank, passing downtown. There are 2×3 lanes available, and the road is below ground level. Steep hills rise right next to the highway. On the west side of downtown, US 26 exits and leads to the western suburbs. The I-405 then has 2×2 lanes with weaving sections. Here too, the road is below ground level, with a viaduct of intersecting streets every 60 meters. The Fremont Bridge, a double-deck arch bridge, crosses the Willamette River in 2×4 lanes. Then I-405 rejoins Interstate 5 toward Seattle.
History
A highway along the west side of Downtown Portland was recommended in 1943 by famed road builder Robert Moses in his “Portland Improvement Report.” In 1955, plans were presented for two freeways, the Sunset Freeway and the Stadium Freeway, both of which were later combined into one bypass of Downtown Portland. At the end of 1964, the clearing of the route for buildings began. Purchasing the route cost $25 million, a huge sum for the time. construction of the sunken parts started in 1967. The construction was technically complex, with 55 retaining structures, 15 viaducts and 4 tunnels located 2 kilometers away. Most of I-405 opened on February 25, 1969, except for the bridge over the Willamette River, the Fremont Bridgewhich was built a little later and opened on November 15, 1973. Construction of I-405 had cost a total of $121 million and was the most expensive project in Oregon state history at the time.
Traffic intensities
Every day, 80,000 vehicles travel between I-5 and US 26 on the south side of downtown, 119,000 vehicles between US 26 and US 30 on the west side of downtown, and 128,000 vehicles between US 30 and I-5 on the north side of downtown.
