Final Off-Ramp Opens at I-5 Exit in Oregon

The Oregon Department of Transportation reports that the I-5 Exit 24 northbound off-ramp opened to traffic this morning, the last permanent ramp to open on the new Interstate 5 Phoenix interchange.

With the opening, the I-5 speed limit in the project area will be increased to 65 mph.

Work continues throughout the project area, primarily the west side of the interchange.

Prime contractor Hamilton Construction of Springfield continues construction on the new Bear Creek Bridge, Greenway connections, and Oregon 99. The contract end date is September 30.

The $72 million Fern Valley Interchange project, which began in 2014, features a Diverging Diamond Interchange design, the first in Oregon and the first on the West Coast. Under this design, traffic moves to the opposite (left) side as it crosses the bridge. The design keeps traffic moving more safely and efficiently than standard diamond interchanges.
