Interstate 105

Home » Guides » Oregon » Interstate 105


Interstate 105 and Oregon Route 126 overlap for 4.99 miles between Downtown Eugene and I-5 near the Springfield city line. The freeway depart the central business district along an elevated viaduct north across the Willamette River. Just north of the river is the interchange with the Delta Highway, a freeway linking I-105/OR 126 north with the Belt Line Highway, a bypass route along the north edge of the city. From the Delta Highway interchange, I-105/OR 126 travel north of Autzen Stadium, home of the Oregon Ducks football team, east to Interstate 5. OR 126 continues east from I-5/105 as a freeway north of Downtown Springfield.

The Interstate 105 Improvement Project repaved the freeway with asphalt, upgraded the guard rails and median barriers to modern standards, and added auxiliary lanes between Delta Highway (Exit 1) to Coburg Road (Exit 2) and Coburg Road (Exit 2) to I-5 (Exit 4). A $13 million contract was awarded in December of 2004 with completion by November 2005.1

The first section of Interstate 105 to open was the segment between Coburg Road (Exit 2) and Laura / Q Streets, just across the Springfield city line, in 1960. The opening of this section coincided with the opening of Interstate 5 between Eugene and Albany. Opening of the Interstate 105 between the interchanges with Coburg Road and Delta Highway (Exit 1) did not occur until 1966 despite completion by 1960.2 The Delta Highway opened at the same time as a county maintained freeway.

From Delta Highway south, Interstate 105 travel across the 1968-completed "Washington-Jefferson Street Bridge" over the Willamette River. The freeway ended temporarily at 1st Avenue as the city of Eugene and state of Oregon debated the final approach into Downtown to 7th / 6th Avenues. Included in the design was an overpass for the unconstructed Roosevelt Freeway, an east-west highway continuing OR 126 west to the Belt Line Highway and city line.

By 1972, OR 126 joins Interstate 105 for its entire length after the decommissioning of U.S. 126. The Springfield section of freeway east of Laura & Q Streets opened to traffic in 1971. In 1973 the final approach to 7th / 6th Avenues opened as an elevated highway with a park underneath. Exit numbers for I-105 originally counted upwards leading west to Downtown, contradictory to the standard east to west numbering system used on Interstate highways. This sequence changed in the early 1990s to start the numbering at 0 in Downtown.
