The highway then tracks a little to the northeast, and I-205 splits off south of the Portland metro area. From here I-5 passes through Tualatin and Tigard along former U.S. Route 99W (US 99W) before hitting the southern terminus of I-405 and the Marquam Bridge. Also planned was a spur in Portland off I-405, called I-505, but it was never built and has been removed from city plans. A stub of I-505 exists as a long exit ramp to US 30.
