If an even number is divided by two, the result is another integer. | Meaning, pronunciation, translations and examples Special routes, which can be labeled as alternate, bypass or business, depending on the intended use, provide a parallel routing to the mainline U.S. Highway. After construction was completed, many U.S. Some exceptions exist, however, such as spur routes (for instance, US 522 is signed north-to-south, while its parent US 22 is signed east-to-west). A few major connections not served by Interstate Highways include US 6 from Hartford, Connecticut, to Providence, Rhode Island and US 93 from Phoenix, Arizona to Las Vegas, Nevada, though the latter is planned to be upgraded to Interstate 11. That said, since we're dealing with an approximation anyway, either meaning seems to work okay. Within the route log, "U.S. Route" is used in the table of contents, while "United States Highway" appears as the heading for each route. Interstate Highway numbers increase from west-to-east and south-to-north, to keep identically numbered routes geographically apart in order to keep them from being confused with one another,[7] and it omits 50 and 60 which would potentially conflict with US 50 and US 60. The Pythagoreans divided the numbers into two groups: odd and even, male and female, light and dark etc. Pythagoras believed numbers had souls, as well as magical powers.. In effect, each of the two routes received the same number, with a directional suffix indicating its relation to the other. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Highways) is an integrated network of roads and highways numbered within a nationwide grid in the contiguous United States. Here is part of a quote from the paper: odd became used in constructions of the type NUM N1 (and) odd N2, where N2 is a count noun of lower rank than N1 (OED lemma 3b,c). From Simple English Wikipedia, the free encyclopedia, https://simple.wikipedia.org/w/index.php?title=Odd_number&oldid=7001718, Creative Commons Attribution/Share-Alike License. [29], The original major transcontinental routes in 1925, along with the auto trails which they roughly replaced, were as follows:[1][9], US 10, US 60, and US 90 only ran about two thirds of the way across the country, while US 11 and US 60 ran significantly diagonally. I agree with your interpretation of "80-odd", and I also say "80-some-odd" with the same meaning. Generally, most north-to-south highways are odd-numbered, with the lowest numbers in the east, and the highest in the west. Routes do not have a minimum design standard, unlike the later Interstate Highways, and are not usually built to freeway standards. est 1. Both definitions can be found, as you pointed out. They received complaints from across the country about the assignment of routes, so the board made several modifications; the U.S. Highway System was approved on November 11, 1926. [8] Not all spurs travel in the same direction as their "parents"; some are connected to their parents only by other spurs, or not at all, instead only traveling near their parents, Also, a spur may travel in different cardinal directions than its parent, such as US 522, which is a north–south route, unlike its parent US 22, which is east–west. Odd numbers are in between the even numbers. [4] As of 1989, the United States Numbered Highways system had a total length of 157,724 miles (253,832 km). I knew she must have meant 20-odd years ago, but got to wondering about the expression itself. Each state manufactures their own signage, and as such subtle variations exist all across the United States. In 1952, AASHO permanently recognized the splits in US 11,[12] US 19, US 25, US 31, US 45, US 49, US 73, and US 99. spoken a little more than 20 etc: [eg] I have another 20-odd years to work before I retire. It had never occurred to me that people interpret might this expression in different ways. [1], Secretary Howard M. Gore appointed the Joint Board on Interstate Highways, as recommended by AASHO, on March 2, 1925. Routes do meet those standards. [22] In addition, U.S. Route 15 had been extended across Virginia. New additions to the system must serve more than one state and "substantially meet the current AASHTO design standards". Similarly, east-to-west highways are typically even-numbered, with the lowest numbers in the north, and the highest in the south. Occasionally only one of the two routes is suffixed; US 6N in Pennsylvania does not rejoin US 6 at its west end. By 1957, AASHO had decided to assign a new grid to the new routes, to be numbered in the opposite directions as the U.S. Highway grid. [17], In the early 1910s, auto trail organizations—most prominently the Lincoln Highway—began to spring up, marking and promoting routes for the new recreation of long-distance automobile travel. "[24] (A popular song later promised, "Get your kicks on Route 66!") It means "eighty-something." [1], In the Northeast, New York held out for fewer routes designated as US highways. [1] The board sent the report to the Secretary of Agriculture of October 30, and he approved it November 18, 1925. AASHO described its renumbering concept in the October 1934 issue of American Highways:[12], "Wherever an alternate route is not suitable for its own unique two-digit designation, standard procedure assigns the unqualified number to the older or shorter route, while the other route uses the same number marked by a standard strip above its shield carrying the word 'Alternate'. US 60's violation of two of the conventions would prove to be one of the major sticking points; US 60 eventually was designated as US 66 in 1926, and later it became a part of popular culture. usually before noun an odd number is a whole number that cannot be divided exactly by two, for example 1, 3, 5, 7 etc Synonyms and related words Words used to describe numbers Different people may differently interpret odd, as noted in comments to the ELU question, and as illustrated by differences between the Longman Dictionary entry quoted above (in brief, “ a little more than”) and the MacMillan Dictionary entry mentioned in J.R.'s comment: “in the region of: used after a number for saying that it is not exact”.
