On Thursday (Dec 8), Massachusetts highway officials plan to install a mileage sign on the eastern end of the road in Boston's Kenmore Square. The sign will inform motorists that Newport, Oregon, is a mere 5415km away on Route 20 westbound.
A similar sign will go up in Newport on Thursday marking the same distance, 5415km to Boston should drivers want to travel the entire way eastbound on Route 20.
The road passes through 12 states on its path between the Atlantic and Pacific Oceans.
