  • Last Link of I-90 Ends 30-Year Saga by Peggy Reynolds, Seattle Times, 9 Sept 1993

    Last Link of I-90 Ends 30-Year Saga by Peggy Reynolds, Seattle Times, 9 Sept 1993

    Last Link Of I-90 Ends 30-Year Saga By Peggy Reynolds, Seattle Times, 9 Sept 1993 Erica Clibborn's red convertible will be one of the first cars Sunday across the new Lacey V. Murrow Floating Bridge, last link in a project that started before Erica was born. The University of Washington junior, who will be going home to Mercer Island for Sunday dinner, was born in 1973, the year a federal court sent the Seattle-area stretch of Interstate 90 back to square one. By then, I-90 already reached most of the 3,063 miles from Boston to south Bellevue, and the final major segment had been in the works for 10 years. It would be another 20 years before that last 7 miles would be finished. That completion will be marked this weekend with an array of public events, and Clibborn and other drivers should be able to go across the eastbound span by 5 p.m. Sunday. That opening means that I-90 survived the anti-government sentiment of the late 1960s, the mass-transit worship of the '70s and the budget cutbacks of the '80s - even while other urban interstate projects were biting the dust in New York, Chicago, Baltimore, Philadelphia, Washington, San Francisco and Portland. Nevertheless, whether or not I-90 was really needed was subject to debate at all levels. It attracted a formidable enemies list, and was rescued regularly by a cast of hundreds. Without any one of its friends in local governments, on the state Transportation Commission, in the Legislature and in Congress, I-90 could have ended in south Bellevue instead of making it to its junction with Interstate 5 in Seattle.

  • Portland-Milwaukie Light Rail Project Profile, Oregon

    Portland-Milwaukie Light Rail Project Profile, Oregon

    Portland-Milwaukie Light Rail Project Portland, Oregon (January 2015) The Tri-County Metropolitan Transportation District of Oregon (TriMet) is constructing a double-track light rail transit (LRT) extension of the existing Yellow Line from the downtown Portland transit mall across the Willamette River, to southeast Portland, the city of Milwaukie, and urbanized areas of Clackamas County. The project includes construction of a new multimodal bridge across the Willamette River, one surface park-and­ ride lot facility with 320 spaces, one park-and-ride garage with 355 spaces, expansion of an existing maintenance facility, bike and pedestrian improvements and the acquisition of 18 light rail vehicles. Service will operate at 10-minute peak period frequencies during peak periods on weekdays. The project is expected to serve 22,800 average weekday trips in 2030. The project will increase transit access to and from employment and activity centers along the Portland and Milwaukie transportation corridor. It will link Downtown Portland with educational institutions, dense urban neighborhoods, and emerging growth areas in East Portland and Milwaukie. The Willamette River separates most of the corridor from Downtown Portland and the South Waterfront. The corridor’s only north-south highway (Highway 99E), which provides access to Downtown Portland via the existing Ross Island, Hawthorne, Morrison, and Burnside bridges, is limited to two through-lanes in each direction for much of the segment between Milwaukie and central Portland, most of which is congested. Existing buses have slow operating speeds due to congestion, narrow clearances and frequent bridge lift span openings. None of the existing river crossings provide easy access to key markets.
