Washington → Oregon · Interstate 5
Retracing the scenic corridor between Seattle, Washington, and Portland, Oregon, in reverse uncovers angles missed on the outbound run — afternoon-lit hillsides, overlooks that sit on the left now, calm beaches that were busy in the morning. It is the same 276 km (172 miles) and roughly 2h 38m along Interstate 5, only seen with fresh eyes. Seattle (the Pacific Northwest tech hub and largest city in Washington State) slips behind, while Portland (the largest city in Oregon and Pacific Northwest cultural and freight gateway) welcomes the driver in the late afternoon. Fuel sits around $23.09 for 25.1 liters (6.6 gallons). Return reimbursement totals $118.68 at the $0.43/km tariff. On the Clara receipt, note the scenic corridor in the observations field to feed the internal catalog of business-tourism routes. Attach a photograph of the closing odometer alongside the exact arrival timestamp, particularly if the return crossed sunset — that detail helps the back office confirm hours-of-service when there is doubt about total time worked. To close the loop, update the corporate expense application with each scenic stop made along the way, even when no fiscal receipt was generated, so the operations log reflects the full traveled corridor.
