The extension will connect Beaverton, Portland International Airport, and the Gateway Center allowing passengers to travel from Hillsboro to the airport.

The total cost of the project is $215 million.

Construction of the project will include laying track and switch and signalization work. This will allow the line to serve an additional 10 stations currently only serviced by the Blue Line. A new  operator break facility will also be added at the Red Line’s terminus in Hillsboro.

The project will also add a second track to two portions of the Red Line that currently run single track and contribute a good deal of congestion. Additionally, the Portland International MAX Station will be rebuilt and a new station at the Gateway/NE 99th Ave Transit Center will be constructed. 

To help keep up with increased ridership due to the expansion, four new light rail vehicles will be added to the MAX Light Rail Service.
