INTERSTATE 5 (Pacific Highway), Exit 24, Fern Valley (Phoenix) Interchange ($72 million)
Crews are currently working on the Bolz Rd./Oregon 99 signals today.
That means traffic will be open to East Bolz Rd., but still in a single lane while construction continues. East Bolz Rd. will become a one-way eastbound toward I-5 from the new Oregon 99 signal. North Phoenix Rd. (formerly Fern Valley Rd.) west of the Bear Creek Bridge will be one-way westbound.
Meantime, the contractor is working on the Bear Creek Bridge, so that will still be in a construction configuration for a while longer.  Traffic is on the south side of the new Bear Creek Bridge so sidewalks, tube rail and signs can be installed on the far north side bridge.
Oregon 99 work continues near the Ray’s Market entrance and Oregon 99.
Greenway trail under the Bear Creek Bridge and the south approach is scheduled to open August 10. The north approach, integral to the temporary ramp to North Phoenix Road, will be closed and rebuilt

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.
