Yes, they just finished paving that section. I rode it and it was really nice. I wasn't sure how smooth it would be so I rode my mountainbike, but I will definitely take the roadbike out next time. We parked at the Oaks Park trailhead and road past OMSI along the river across the bridge, past heroin plaza, then back across the Hawthorne Bridge towards OMSI and back to Oaks Park. Great ride, no traffic. Only one little section is on back roads.
