Bear Creek Greenway detour to change in August

PHOENIX — Bear Creek Greenway are now using a modified detour across Fern Valley Road, part of the Fern Valley Interchange project. Greenway traffic south of Fern Valley Road is begin directed to follow a detour along Bolz Road before connecting with the existing Greenway path.
The change  is needed for the safe construction of the southern half of the new Bear Creek Bridge on Fern Valley Road. The bridge’s first half was completed earlier this summer.
“To be safe at the crossing, Greenway users need to use the Rapid Flashing Beacon warning system,” said Jackson County Greenway coordinator Jenna Stanke. “And then make sure drivers are going to stop.”
ODOT encourages Greenway users and motorists to use extra caution when passing through the at-grade crossing, especially in the busy work zone.
When complete, the Greenway will return to its original alignment, passing under the new structure that spans Bear Creek. The $72 million Fern Valley Interchange project is scheduled for completion in September 2016. When complete, exit 24 will feature Oregon’s first Diverging Diamond Interchange, which uses a narrower footprint to move traffic safely and efficiently while saving right of way costs.




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.

Diverging Diamond Interchange


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.
