Jackson Bridge reduced traffic on the older Interstate Bridge from over 116,000 vehicles per weekday in 1982 to 96,000 in 1986; Glenn L. Jackson Bridge carried 61,000 vehicles in 1986 and has a capacity of 140,000 daily vehicles. By 1996, traffic on the bridge had exceeded that on the Interstate Bridge, and I-205 was used the following year as a major detour route during repairs to the older bridge. For several months in 2000, the Glenn L. Jackson Bridge underwent weekend closures to allow for the replacement of its expansion joints, which had been damaged by increased traffic. The Clackamas River Bridge on I-205 in Gladstone underwent similar expansion joint replacements over an eleven-month period in 2001. To manage congestion, ODOT installed ramp meters at 11 locations along I-205 from 1999 to 2001 and worked with Metro to study other solutions, which were deemed infeasible due to a lack of funds for substantial construction. The Sunnyside Road interchange, which handled 50,000 daily vehicles and remained congested due to growth at the Clackamas Town Center, was rebuilt from 2001 to 2003 at a cost of $28 million (equivalent to $ in dollars). The project split the interchange between Sunnyside Road and an extended Sunnybrook Boulevard to the south with frontage roads between the two overpasses. In 2007, at the suggestion of congressperson Darlene Hooley, a section of the freeway from Tualatin to West Linn was widened to six lanes through the reuse and upgrade of temporary lanes that were constructed for a repaving project. The Washington state government funded two improvements to the Mill Plain Boulevard interchange on I-205 in Vancouver through its 2003 and 2005 legislative packages. The first stage, which was completed in October 2009, added an offramp to Chkalov Drive (named for Soviet pilot Valery Chkalov) to bypass its congested intersection with Mill Plain. The second project added a set of braided ramps to a new interchange with Northeast 18th Street, which opened in July 2016 at a cost of $40.6 million. Both projects were proposed in the 1990s, initially as a split interchange with 18th and 28th streets, amid a development moratorium on Mill Plain that the City of Vancouver imposed due to traffic congestion.
