Fern Valley Interchange
Traffic is scheduled to switch to the south side of the new Bear Creek Bridge, Monday, June 27 so sidewalks and tube rail can be installed on the far north side bridge.
Work continues on the permanent northbound off-ramp, which is scheduled to open in later in July.
Contractor is working on returning Luman Rd. back to its original alignment after use as temporary SB on and off-ramps. Luman Rd. traffic should expect short delays and flagging.
 Greenway trail under the Bear Creek Bridge and new approaches are under construction through next month.
All Interstate 5 lanes are open in the project area, and speeds are reduced to 50 MPH in the work zone.

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.
