Old route question

The Interstate.

 

Many of the states have decommissioned US-66 and re-titled working sections to state Route 66. Couldn't tell you why they did this except maybe the Feds decided they would not continue to fund parts of their upkeep since many sections are unnecessary now because of interstate development.

 

Here is the Wikipedia article of decline of Route 66.

The beginning of the decline for US 66 came in 1956 with the signing of the Interstate Highway Act by President Dwight Eisenhowerwho was influenced by his experiences in 1919 as a young Army officer crossing the country in a truck convoy (following the route of the Lincoln Highway), and his appreciation of the German Autobahn network as a necessary component of a national defense system.[32]

During its nearly 60-year existence, US 66 was under constant change. As highway engineering became more sophisticated, engineers constantly sought more direct routes between cities and towns. Increased traffic led to a number of major and minor realignments of US 66 through the years, particularly in the years immediately following World War II when Illinois began widening US 66 to four lanes through virtually the entire state from Chicago to the Mississippi Riverjust east of St. Louis, Missouri, and included bypasses around virtually all of the towns. By the early to mid-1950s, Missouri also upgraded its sections of US 66 to four lanes complete with bypasses. Most of the newer four-lane 66 paving in both states was upgraded to freeway status in later years.

One of the remnants of US 66 is the highway now known as Veterans Parkway, east and south of Normal, Illinois, and Bloomington, Illinois. The two sweeping curves on the southeast and southwest of the cities originally were intended to easily handle traffic at speeds up to 100 miles per hour (160 km/h), as part of an effort to make Illinois 66 an Autobahn equivalent for military transport.

In 1953, the first major bypassing of US 66 occurred in Oklahoma with the opening of theTurner Turnpike between Tulsa and Oklahoma City. The new 88-mile (142 km) toll road paralleled US 66 for its entire length and bypassed each of the towns along 66. The Turner Turnpike was joined in 1957 by the new Will Rogers Turnpike, which connected Tulsa with the Oklahoma-Missouri border west of Joplin, Missouri, again paralleling US 66 and bypassing the towns in northeastern Oklahoma in addition to the entire state of Kansas. Both Oklahoma turnpikes were soon designated as I-44, along with the US 66 bypass at Tulsa that connected the city with both turnpikes.

In some cases, such as many areas in Illinois, the new interstate highway not only paralleled the old US 66, it actually incorporated much of it. A typical approach was to build one new set of lanes, then move one direction of traffic to it, while retaining the original road for traffic flowing in the opposite direction. Then a second set of lanes for traffic flowing in the other direction would be constructed, finally followed by abandoning the other old set of lanes or converting them into a frontage road.

The same scenario was used in western Oklahoma when US 66 was initially upgraded to a four-lane highway such as from Sayre through Erick to the Texas border at Texola in 1957 and 1958 where the old paving was retained for westbound traffic and a new parallel lane built for eastbound traffic (much of this section was entirely bypassed by I-40 in 1975), and on two other sections; from Canute to Elk City in 1959 and Hydro to Weatherford in 1960, both of which were upgraded with the construction of a new westbound lane in 1966 to bring the highway up to full interstate standards and demoting the old US 66 paving to frontage road status. In the initial process of constructing I-40across western Oklahoma, the state also included projects to upgrade the through routes in El Reno, Weatherford, Clinton, Canute, Elk City, Sayre, Erick, and Texola to four-lane highways not only to provide seamless transitions from the rural sections of I-40 from both ends of town but also to provide easy access to those cities in later years after the I-40 bypasses were completed.

In New Mexico, as in most other states, rural sections of I-40 were to be constructed first with bypasses around cities to come later. However, some business and civic leaders in cities along US 66 were completely opposed to bypassing fearing loss of business and tax revenues. In 1963, the New Mexico Legislature enacted legislation that banned the construction of interstate bypasses around cities by local request. This legislation was short-lived, however, due to pressures from Washington and threat of loss of federal highway funds so it was rescinded by 1965. In 1964, Tucumcari and San Jon became the first cities in New Mexico to work out an agreement with state and federal officials in determining the locations of their I-40 bypasses as close to their business areas as possible in order to permit easy access for highway travelers to their localities. Other cities soon fell in line including Santa Rosa,Moriarty, Grants and Gallup although it wasn't until well into the 1970s that most of those cities would be bypassed by I-40.

By the late 1960s, most of the rural sections of US 66 had been replaced by I-40 across New Mexico with the most notable exception being the 40-mile (64 km) strip from the Texas border at Glenrio west through San Jon to Tucumcari, which was becoming increasingly treacherous due to heavier and heavier traffic on the narrow two-lane highway. During 1968 and 1969, this section of US 66 was often referred to by locals and travelers as "Slaughter Lane" due to numerous injury and fatal accidents on this stretch. Local and area business and civic leaders and news media called upon state and federal highway officials to get I-40 built through the area; however, disputes over proposed highway routing in the vicinity of San Jon held up construction plans for several years as federal officials proposed that I-40 run some five to six miles (8 to 10 km) north of that city while local and state officials insisted on following a proposed route that touched the northern city limits of San Jon. In November 1969, a truce was reached when federal highway officials agreed to build the I-40 route just outside the city, therefore providing local businesses dependent on highway traffic easy access to and from the expressway via the north–south highway that crossed old US 66 in San Jon. I-40 was completed from Glenrio to the east side of San Jon in 1976 and extended west to Tucumcari in 1981, including the bypasses around both cities.

Originally, highway officials planned for the last section of US 66 to be bypassed by interstates in Texas, but as was the case in many places, lawsuits held up construction of the new interstates. The US Highway 66 Association had become a voice for the people who feared the loss of their businesses. Since the interstates only provided access via ramps at interchanges, travellers could not pull directly off a highway into a business. At first, plans were laid out to allow mainly national chains to be placed in interstate medians. Such lawsuits effectively prevented this on all but toll roads. Some towns in Missouri threatened to sue the state if the US 66 designation was removed from the road, though lawsuits never materialized. Several businesses were well known to be on US 66, and fear of losing the number resulted in the state of Missouri officially requesting the designation "Interstate 66" for the St. Louis to Oklahoma City section of the route, but it was denied. In 1984, Arizona also saw its final stretch of highway decommissioned with the completion of I-40 just north ofWilliams, Arizona. Finally, with decertification of the highway by the American Association of State Highway and Transportation Officialsthe following year, US 66 officially ceased to exist.

With the decommissioning of US 66, no single interstate route was designated to replace it.I-55 covered the section from Chicago to St. Louis; I-44 carried the traffic on to Oklahoma City; I-40 took the largest chunk, replacing 66 to Barstow, California; I-15 took over for the route to San Bernardino; and I-210 and State Route 2 (SR 2) or I-10 carried the traffic of US 66 across the Los Angeles metropolitan area to Santa Monica, and the seashore.

 

OK66 between Oklahoma City and Vinita still is a neat route to take.

Many sections of the old highway still exist.

 

Apparently most good sections were incorporated into the Interstate, and the bad sections abandoned. There are a few sections left, like Packrat says.

There are other Interstates that the us highway runs concurrent, but the sections that aren't interstates seem to be intact. US 6 comes to mind.

 

Lightning McQueen could probably give us a good answer.
