United States
In the US, many Interstate Highways have spur routes when they enter a large metropolitan area. Interstate spur routes are numbered with a three-digit number. The last two digits of the number are the number of the "parent" Interstate; e.g. a spur route of Interstate 90 could be 990, a spur route of Interstate 5 could be 105.
Spur Interstate routes have three-digit numbers with an odd first digit. A subsidiary route either passing through a city or bypassing it and then reconnecting to a major highway would receive an even first digit, and be considered a loop rather than a spur. For example, in the case of Interstate 5, Interstate 105 is a spur route ending at Los Angeles International Airport, whereas Interstate 405 begins and ends at Interstate 5, bypassing downtown Los Angeles.
Spurs are also found branching from US highways, state routes, and county routes, often as extended onramps and offramps of expressways.
There are many numbering violations in the spur route numbering system, thus the general rules above do not always apply.

And of Priapus in the shrubbery
Gaping at the lady in the swing.”
