Interstate 5 navigates through Multnomah County entirely within the Portland city limits. The freeway enters the county in southwest Portland, where hilly terrain makes for a winding trip from Exits 294 to 298. After Interstate 405 splits off toward Downtown at Exit 299B, I-5 crosses the Willamette River over the two-level Marquam Bridge and follows the east bank of the Willamette River. North from there, the freeway proceeds through a network of overpasses and flyover ramps at the exchanges with Interstate 84 east and the north end of I-405 (Stadium Freeway). The river bends west, and I-5 continues a northbound trajectory through Portland neighborhoods to the Columbia River

| A truck lane splits from the I-5 mainline just past Exit 294. According to ODOT, the lane was added in 1983 to keep slow-moving trucks, which are heading up a moderate grade, to the outside of a flyover ramp merging onto northbound I-5 from OR 99W. 06/26/05 |

I-405 initially follows SW Harbor Drive before turning west via a flyover ramp onto the Stadium Freeway north around Downtown Portland to U.S. 26 (Sunset Highway) west. 08/27/06 |
|
| Until 1974, Southwest Harbor Drive spurred north through the Riverplace neighborhood toward the Steel Bridge along the Willamette Riverfront.

|
| Once off the Marquam Bridge at milepost 301, northbound I-5 enters a labyrinth of overpasses and flyover ramps. Except for some auxiliary lanes, northbound traffic will now be squeezed into two lanes until just past the northern interchange with I-405. 10/30/05 |
|
| I-5 northbound passes under the knot of ramps taking traffic to and from the Morrison Bridge. There is no direct access to the bridge from northbound I-5; the ramps originate mostly from surface streets and the bridge itself. The Morrison Bridge connects west side Washington and Alder streets with east side Morrison and Belmont streets. 10/30/05 |
