1992 was the first time I went through Norton. At the time I was not yet what I would describe as a "roadgeek", but I still thought this sign was worth stopping for a photo:
From humble beginnings to great lengths
US 83 was among the inaugural routes of 1926. But at the time, and for the next couple years, it was a very short route -- only about 170 miles long -- running between the capital cities of the two Dakotas:
However, by the early 1930s the US 83 designation had been extended not only north to the Canada border, but all the way down to the Mexico border too. This increased US 83's distance to nearly 1900 miles, and made it one of the longest north-south US routes. Additionally, as a result of US 83's new role as a trunk route, three newer US routes were numbered as branches of US 83. Two of these soon became quite lengthy themselves, and they still exist (US 183 and US 283). Just as these highways intertwine with each other, their history is also interrelated. This article examines the evolution of US 83, as well as the x83 routes that are part of its "family".
US 50 is one of the longest highways in the U.S. How long is it? Well, there's actually some debate on that (this page has more details about why that is).
Both the Maryland and California state departments of transportation have placed reciprocal mileage signs at the terminus points, each claiming the total distance is 3073 miles. This photo was taken in Ocean City MD, looking along the east beginning of US 50...
In 1967 the US 270 designation was at its maximum extent, from Pine Bluff AR to Syracuse KS. That year the Kansas DOT petitioned AASHO* to extend the US 270 designation even further:
