Drive It!


The new interchange bridge is being constructed just north of the existing bridge, leaving most roadways west of the interchange relatively untouched. The Diverging Diamond interchange design has a narrow footprint, which helps avoid touching most businesses during and after the project.

Project Background

The $72 million Fern Valley Interchange project began in in the spring of 2014. Due to the projects size and complexity - it encompasses east and west Phoenix roadways, I-5 and Oregon 99 - the project requires more than two full construction seasons, finishing in September 2016. It also includes bike and pedestrian connections.
The federally-required enviromental process began in 2004, and ended with a completed Fern Valley Environmental Assessment in 2010 and a Finding of No Significant Impact (FONSI) in 2011J.
