Utah → Arizona · Interstate 15 / Interstate 80
The long-haul return between Salt Lake City, Utah, and Phoenix, Arizona — another 960 km (597 miles) along Interstate 15 / Interstate 80 — closes a journey that hardly fits inside a single business day. Reserve another 9h 9m on the schedule and consider a second overnight if departure happens at the close of business hours. Anyone driving back from Salt Lake City (the capital of Utah and the gateway to the Wasatch Range and the Great Basin) often pulls into Phoenix (the fifth-largest US city and capital of Arizona) over the weekend. Incremental fuel adds $80.32 (87.3 liters / 23.1 gallons). Return reimbursement reaches $412.80 at the $0.43/km tariff. Reconcile outbound and return inside a single Clara PDF, with hotels itemized as separate line items, so finance can reimburse the full bundle in one batch. Priority processing happens when all supporting documents (fuel invoice, toll receipt, hotel folio, meal receipts) sit attached in chronological order and identified by the originating project number. For trips longer than three days, the finance department may also require an executive visit summary attached, describing objectives achieved, agreed next steps, and the commercial indicators generated.
