Шаблон:Short description Шаблон:Infobox 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 (later renamed Veteran's Memorial Freeway), Interstate 205. Construction began in August 1977. In order to avoid disrupting river traffic, the bridge was built one segment at a time. The segments, weighing upwards of 200 tons, were cast Шаблон:Convert downstream and barged into place. The bridge was opened on December 15, 1982.[1][2] The finished project cost was $169.6 million: $155.7 million from Federal funds, $4 million from Washington state funds and $9.9 million from Oregon state funds.[3] Three men died during its construction.[4] The bridge was closed to traffic on May 15, 1983, for a one-day festival named "People's Day", where 125,000 pedestrians crossed the bridge.[5]
It is a twin structure with four lanes in each direction and a Шаблон:Convert bicycle and pedestrian path in between. The bridge is Шаблон:Convert long from the Washington side of the river to Government Island and another Шаблон:Convert in length from Government Island to the Oregon side of the river. The main span, near the Washington side, is Шаблон:Convert long with Шаблон:Convert of vertical clearance at low river levels. The bridge was named for Glenn Jackson, the chairman of the Oregon State Highway Commission and later the Oregon Economic Development Commission.[6]
The average weekday traffic during 2019 was 166,152 vehicles.[7] In 2020, ODOT and WSDOT began a one-year pilot project to allow C-Tran buses to use the shoulders of I-205 over the bridge in order to bypass congestion.[8]
No vehicle, bicycle or pedestrian access to Government Island is available from the bridge.
Multi-use path
A multi-use path for pedestrians and cyclists runs along the center of the bridge. This multi-use path connects to two trailheads at each end of the bridge as well as the I-205 Trail through Portland.[9]Шаблон:Unreliable source? The path lacks access to Government Island.
