Grids in which one numbered street extends far longer than its peers

In Anoka County, MN, 7th Avenue serves as an arterial through the city of Anoka, influenced by the grid of downtown. North of downtown, it enters the city of Andover as 7th Avenue NW, escaping the grid of Anoka and becomes influenced by the county-wide grid. The county grid, in turn, is influenced by NE Minneapolis.

Outside Cleveland, OH, West 130th Street continues for 18 miles from its origin at OH 10/Lorain Ave all the way to its endpoint at OH 3/Weymouth Road near Exit 222 on I-71. No other Cleveland numbered street gets anywhere south of central Parma, about 8 miles south of downtown.

3rd Ave in NYC is the only numbered avenue that continues into the Bronx.

In Washington DC, there was the historic "7th street road" or "7th street pike" that used to extend for many miles into Maryland.  The section north of the old city boundary (Florida Ave) was renamed to Georgia Ave.

In Los Angeles, you have Ave. 64 which is the only one of the series of streets that goes into Pasadena.  This is a weird numbering pattern, not really a grid, just sort of numbering the streets that North Figueroa intersects.

L.A. has some other weird ones.  18th street (not continuous) does go all the way out to Robertson.  190th goes all the way to the city of Redondo Beach.  As stated earlier, 3rd is a major arterial to the west and continues unimpeded all the way to Beverly Hills.

In Jeffersonville, IN, 10th Street is much, much longer than any other numbered street.

Las Vegas has North 5th street.

It is an interesting case.  In the Downtown area, with all of the other numbered streets, 5th street is now named as part of Las Vegas Blvd. But the 5th street moniker would continue north a very long way.  The current 5th street starts at the northern intersection of LV Blvd and Main Street, which is north of Owens Ave. (the city line)  No other numbered street exists north of Owens Ave.  So a very long time ago, this met the other examples of this thread, now we have a real outlier, a numbered street that only exists way outside the core of the grid, due to street renaming.

The City of Concord, CA has a weird set of four numbered streets: 2nd, 3rd, 5th, and 6th.  2nd, 3rd, and 5th are no more than a couple of blocks long, yet 6th st continues for a distance of nearly 2 miles.  Why there are no other numbered streets, or why the numbered street scheme was abandoned is an open question.

I don't know if 9 mile road counts in Detroit. It is a numbered street that runs across the north part of Detroit, out through the suburbs, and ends at US-23 to the west. The total distance from US-23 to where it dead ends near Lake St. Clair is 45.3 miles.

N 8th St (and N 8th Street Rd) in Springfield, IL extends way further north than the rest of the numbered streets in the city's grid, even though the entire length is technically within the city limits.

These are not numbered streets but I'm going to mention them anyway - Broad Street and Hull Street in the City of Richmond, VA (and Henrico County) extend into the surrounding counties as Broad Street Rd and Hull Street Rd. Hull Street Rd continues through Chesterfield County before becoming Patrick Henry Hwy at the Chesterfield/Amelia county line, while Broad Street/Broad Street Rd continues over 30 miles westward until becoming Three Notch Rd at the Goochland/Louisa county line (although there is a segment that briefly crosses into Louisa County and remains Broad Street Rd).

18th Avenue in Belmar (Monmouth CR 30) extends out all the way to Allaire State Park, though it is interrupted by the GSP interchange with NJ-34.

In New York City you have First Street not even a block long, but the rest of them pretty much span Manhattan.
