May be enough long-haul truck volume to support southern segment from Seattle to Oregon, but would require some public funding

To be financially feasible, a two-lane truck-toll highway south of Seattle would need to divert 50% of long-haul trucks from I-5. Trucks could pay up to a $60 toll (about $0.60/mile)
