Glenn L. Jackson Memorial Bridge

The Glenn L. Jackson Memorial Bridge, or I-205 Bridge, is a segmental bridge that spans the Columbia River between Portland, Oregon and Vancouver, Washington. It carries Interstate 205, a freeway bypass of Portland, Oregon. The structure is maintained by the Oregon Department of Transportation.

Planning for the structure began in earnest in 1964 when it was designated as part of the East Portland Freeway, Interstate 205. Construction began in August 1977. In order to avoid disrupting river traffic, the bridge was built one segment at a time.
