1. What Is The History Of Interstate 70 And Its End Point?
Interstate 70 (I-70) spans 2,153 miles, ranking it as the fifth-longest Interstate highway in the United States. The decision to terminate I-70 in Cove Fort, Utah, is rooted in a complex interplay of historical, political, and strategic considerations, rather than a simple geographic or logistical choice. The initial plans for the Interstate System envisioned an east-west route through Colorado. However, disagreements between Colorado and Utah over the route’s precise path west of Denver led to a period of uncertainty.
1.1. Early Plans And Colorado’s Concerns
In 1939 and 1944, reports submitted to Congress outlined an “Interregional System” with an east-west route ending in Denver. Colorado officials were concerned that this plan would isolate them from westward Interstate travel. In 1944, Colorado was the only state to oppose the new highway network. State Highway Engineer Charles D. Vail voiced concerns that the designated routes did not provide direct destinations to the north, west, or south, and that design standards would encourage heavier loading.
1.2. The Federal-Aid Highway Act Of 1944
The Federal-Aid Highway Act of 1944 authorized the designation of a 40,000-mile “National System of Interstate Highways.” The Public Roads Administration (PRA) requested proposals for Interstate routes from state highway officials. Colorado advocated for a northern route along the U.S. 40/6 corridor west of Denver to Spanish Fork, Utah. Utah highway officials, however, expressed concerns about the high costs of meeting design standards in mountainous terrain.
1.3. Initial Designations And Colorado’s Frustration
The initial designation was completed on August 2, 1947, with 37,681 miles of rural Interstate routes. The remaining miles were reserved for urban routes. The east-west Interstate into Colorado ended at Denver. Colorado officials attributed this “dead-end” status to the lack of agreement with Utah on the route west of Denver. Governor William Lee Knous criticized the decision, suggesting it was made by a “pipsqueak bureaucrat in Washington who has never been west of the Mississippi.”
1.4. Renewed Efforts And Congressional Action
Throughout the early 1950s, Colorado officials continued to advocate for an east-west Interstate highway across the state. In March 1955, Governor Edwin Johnson testified before the Senate Subcommittee on Roads, emphasizing the importance of tourism to Colorado’s economy. The Bureau of Public Roads (BPR) prepared internal documents reviewing the issue, noting the high costs of construction and the limited mileage available for the Interstate system. In 1956, the Federal-Aid Highway Act added 1,000 miles to the Interstate System, providing an opportunity to address Colorado’s concerns.
2. How Did Cove Fort Become The Western Terminus Of I-70?
Following the enactment of the 1956 Act, the Bureau of Public Roads (BPR) had 2,102 miles of Interstate to designate, including the 1,000 miles added by the Act and 1,102 miles saved by routing roads along direct paths.
2.1. The Role of the Department of Defense
During final analysis, the BPR identified the Denver-Spanish Fork route as a “Duplication of existing service.” On September 10, 1957, Administrator Tallamy approved an Interstate numbering map with I-70 terminating in Denver. Tallamy sought review from the Department of the Army, whose Chief of Transportation, Major General Paul F. Yount, supported the route only if it provided a direct link to southern California, thus influencing the decision to extend it southward to Cove Fort.
2.2. The Decision To Terminate At Cove Fort
On October 18, 1957, Secretary of Commerce Sinclair Weeks announced the designation of the western extension of I-70 to Cove Fort. The decision was motivated by the desire to provide a direct connection between Denver and southern California, avoiding duplication of service provided by the Denver-Cheyenne-Salt Lake City route.
2.3. Utah’s Reaction And Acceptance
Utah officials were surprised by the decision, as they had agreed with Colorado on the extension to Spanish Fork. The BPR had not informed Utah of the change in the western terminus prior to the announcement. Despite initial opposition, Utah officials ultimately accepted the Cove Fort routing, recognizing the benefits of increased Interstate Construction funding and the trans-mountain link with Colorado.
3. What Is The Significance Of Cove Fort, Utah?
Cove Fort’s history dates back to 1867 when Brigham Young commissioned Ira Hinckley to construct a fort on Cove Creek as a way station for pioneers traveling between Fillmore and Beaver.
3.1. Historical Context
The fort, completed in November 1867, served as a crucial stop for travelers for approximately two decades. Over time, the Fillmore-Cove Fort-Beaver road became a vital north-south route connecting Salt Lake City with the Southwest.
3.2. Inclusion In Named Trails
Cove Fort’s strategic location on the main north-south road led to its inclusion in several named trails, such as the Arrowhead Trail (linking Salt Lake City to Los Angeles), the Evergreen National Highway (connecting Portland, Oregon, to El Paso, Texas), and the Pikes Peak Ocean-to-Ocean Highway (running from New York City to San Francisco, later extending to Los Angeles).
3.3. U.S. Numbered Highway Plan
In November 1926, the American Association of State Highway Officials (AASHO) approved the U.S. numbered highway plan, which included Cove Fort on U.S. 91, a north-south route stretching from Great Falls, Montana, to Daggett, California.
3.4. Modern-Day Importance
Today, Cove Fort remains a notable landmark and tourist destination, attracting visitors with its well-preserved historical significance and convenient location along major transportation routes.
