We need the Western Arterial highway. Otherwise we will have mini-CRC's popping up along the over-used I-5 and US 26 corridors. One mini-CRC is the I-5/Mill Plain Interchange. Exactly what is wrong with it now? Then US 26, Terwiliger Curves, etc. etc. Western Arterial highway (NOT West Side Bypass Freeway) solves all of this.http://oregoncatalyst.com/28327-columbia-river-crossing-alternative-western-arterial.html
