Interstate 5 North - Portland

Interstate 5 navigates through Multnomah County entirely within the Portland city limits. The freeway enters the county in southwest Portland, where hilly terrain results in several S-curves from Exits 294 to 298. Beyond the split with Interstate 405 to Downtown at Exit 299 B, 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.

I-5 weaves northeast between the Crestwood and West Portland Park neighborhoods one mile to Exit 295 for Taylors Ferry Road. Heading east, Taylors Ferry Road navigates across the hills of southwest Portland, eventually reaching OR 43 near the Willamette River.
