While the first half of the bridge is open to traffic, lanes are a narrow 11 feet and the bridge also accomodates bicycle and pedestrians to all traffic must be alert when traveling through the construction zone.

New Bear Creek Bridge opens to traffic

Demolition of old bridge underday 

Traffic is on the first half of the new Bear Creek Bridge. The switch occurred in the early morning hours of Friday, June 12.
Traffic is on a new northern alignment at the bridge and west toward Oregon 99, which allows Hamilton's subcontractor Staton Construction room to demolish the old bridge. Construction on the second half of the bridge will begin shortly when the old bridge is removed.. When complete the new structure will be seamless and look like a new bridge with sidewalks, bike lanes and two traffic.
The demolition and construction below the ordinary high water mark can only be done between June 15 and September 15. Those summer months are called the In Water Work Period set aside to protect migrating fish.
Drivers, pedestrians and bicyclists should continue to travel the area with caution.

The $72 million Fern Valley Interchange project is now in its second year of construction.  Completion is set for September 2016. The Fern Valley Interchange project in Phoenix encompasses I-5, Oregon 99 and Fern Valley Road and will feature Oregon’s first Diverging Diamond Interchange.

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.
