Interstate 5 traffic set for single lane near Phoenix April 21

25 day lane closure needed for pipe crossing


The first major impact to traffic from the Fern Valley interchange project begins Monday, April 21. Both the northbound and southbound lanes will be narrowed to a single lane for 25 days.

The excavation is necessary to install a 4 foot diameter storm water drainage pipe.

“Our technical team looked at all the ways to make the pipe crossing without affecting I-5 traffic,” said ODOT spokesman Gary Leaming. “However, because large boulders were used as road base, they determined the best way to do it is with open trenching.”

That method will mean congestion and delays for interstate traffic. So Rogue Valley motorists should be aware, plan to leave earlier on their trips and consider taking OR 99, North Phoenix Road or RVTD.

Prime contractor Hamilton Construction of Springfield is also excavating the new North Phoenix Road, east of the interchange, as well as cutting the new temporary southbound ramps on the west side of the interstate.

“The large off-road dump trucks are going back and forth across North Phoenix Road, north of the Home Depot. They’re cutting about 184,000 cubic yards of material from the east side of the interstate. Of that amount, nearly 50,000 cubic yards are coming back as fill.

The construction project runs through September 2016.

When complete, exit 24 will feature Oregon’s first Diverging Diamond Interchange. It has a narrower footprint than a typical diamond interchange, which saves on right of way costs and allows construction where development is close to the interchange ramps. It also moves traffic safely and efficiently.

ODOT also has a project office at the Shoppes at Exit 24.
