Noting that federal funds could only be spent on one project at a time, Metro's Joint Policy Advisory Committee on Transportation (JPACT) made the I-205 corridor their next priority after the Westside project and the McLoughlin Boulevard corridor third priority.

The only court that may reverse or modify a decision of the Oregon Supreme Court is the Supreme Court of the United States. promptly struck down this funding due to the inclusion of unrelated measures, which violated the state's constitution.
In February 1996, state legislators revised the package, but light rail opponents forced a statewide vote in November that ultimately prevented the use of state funds.
In an effort to gain the support of North Portland residents, who had historically voted in favor of light rail, and to avoid seeking state funding, TriMet announced a third plan in February 1997 that proposed a line from Lombard Street in North Portland to Clackamas Town Center. The Portland City Council later extended the alignment through North Portland so it would terminate another north of Lombard Street in
Kenton. In August, due to the wording on the original ballot passed in 1994, which described the line extending into Clark County, the TriMet board decided to hold another vote on a new $475 million bond measure. Portland area residents cast their vote on November 3, 1998, and rejected it by 52 percent, effectively canceling the project. Despite the South/North project's cancellation, North Portland residents and city business leaders continued to push for light rail.
In 1999, they urged TriMet to revive the northern portion of the South/North project, which led to the
Interstate MAX and Yellow Line opening in 2004.
Revival and funding
In April 1999, JPACT revived plans for the I-205 and McLoughlin Boulevard corridors by announcing the $8.8 million South Corridor Transportation Study.
The committee published the study's report in October 2000, narrowing a range of transit alternatives for each corridor; it outlined constructing either two light rail lines, a combination of one light rail line and one improved bus service, bus rapid transit, or dedicated bus lanes.
After public meetings concluded in 2003, JPACT recommended both light rail options.
They decided the first MAX line to Clackamas County should be built along the I-205 busway from
Gateway to Clackamas Town Center, and that this would be the first of two phases, the second of which would be a Portland–
Milwaukie line via McLoughlin Boulevard.
While planning for the second phase, alignment studies within downtown Portland showed that a fourth service along the existing tracks on Morrison and Yamhill streets, then served by the

.
The first phase would be completed in 2009, with the transit mall rebuilt with light rail and the Yellow Line rerouted to it in August.
The I-205 segment would open the following month with a new
Green Line service.
In July 2008, Metro adopted a locally preferred alternative (LPA) route for the second-phased Portland–Milwaukie line that began at the southern end of the Portland Transit Mall and terminated at
Southeast Park Avenue in
Oak Grove, just south of Milwaukie proper in
unincorporated Clackamas County; the alignment was extended beyond Southeast Lake Road in downtown Milwaukie,
which had been the terminus in the 2003 LPA.

(FTA) only committed 50 percent, lower than any previous MAX project. Oregon provided the second-largest share at $355.2 million, mostly sourced from
state lottery bond proceeds. Metro, TriMet, Clackamas County, Portland, Milwaukie, and in-kind property donations contributed $249.3 million to the remaining local-match funds. TriMet and the FTA entered into a funding agreement in May 2012.
Clackamas County had originally agreed to allocate $25 million to the project but later negotiated a reduction to $22.6 million due to Measure 3-401, an anti-light rail initiative that light rail opponents placed on the

which meant TriMet could begin purchasing rights-of-way and construction materials.
Construction began on June 30, initially limited to the site of the new Willamette River crossing,
which was temporarily named the "Portland–Milwaukie Light Rail Bridge".
Utility relocation and other preparation work along the project route began later that year. By 2013, major light rail construction work had started in Clackamas County. Safety improvements were made at several street-level crossings in
Southeast Portland and Milwaukie, allowing these areas to be designated quiet zones where

interlined with the Yellow Line when it took over service of the southbound 5th Avenue segment of the Portland Transit Mall.
