The Bank of Vernal (a.k.a. the 'Parcel Post' Bank) Building (3 West Main Street) is a registered historical building in the Uintah County Landmark Register. Also known as "the Bank that was sent by Mail", the Bank of Vernal was constructed in 1916-1917 by William H. Coltharp, a Vernal businessman and entrepreneur. Coltharp took advantage of inexpensive Parcel Post rates to ship some 80,000 masonry bricks in fifty-pound (22.6 kg) packages via the U.S. Post Office the 180 miles (290 km) from Salt Lake City to Vernal. The Parcel Post brick shipments were transported from Salt Lake to Mack, Colorado by Denver & Rio Grande Railroad, then proceeded to Watson via the narrow gauge Uintah Railway, finally Vernal by wagon freight through steep roads. The full trip was over 420 miles (675.9 km) long. After completing delivery of the bricks, the U.S. Post Office hastily changed its regulations, establishing a limit of 200 pounds (91 kg) per day per sender. The United States Postmaster General Albert Sidney Burleson explicitly stated in a letter that "it is not the intent of the United States Postal Service that buildings be shipped through the mail" Today the building is used as a branch office of Zions Bank.
