Sequences of numbered streets that continue into a neighboring county?

[KCRoadFan]

One thing I like to think about is this: where might some places be where, in areas surrounding cities with a series of numbered streets, that sequence of numbers carries on outside the city - not only throughout the county, but into the next county over as well? In addition, how high do the numbers in these multi-county sequences go before they finally end?

Right here at home, in the KC area, I know of several such sequences. The numbered streets in KCMO (and by extension, Jackson County) continue south into Cass County, eventually reaching well into the 300s. On the Kansas side, the numbers in Johnson County (which are based on the KC grid) extend into Miami County, where I believe they go as high as 407th Street.

The separate grid in KCK/Wyandotte County (where the numbered streets run north-south as opposed to east-west like the main KC grid) is another example: those numbers extend west into Leavenworth County, going as high as 258th near the Douglas County line. A little further west in Kansas, the numbers in Shawnee County (which are based on Topeka) extend south into Osage County, reaching as high as 349th Street. Back in Missouri, north of the river, the numbers for Clay and Platte Counties extend north into Clinton County, going into the 200s - but with a twist: the addresses on the north-south roads are not based on the street numbers, but are instead figured from Highway 116, which runs through Plattsburg, the county seat.

Those are just the myriad examples I know from the greater KC region. I know of a couple other examples elsewhere: in Indiana, the street grid in Marion County/Indianapolis extends north into Hamilton County - reaching almost 300, I think. Also, in Minnesota, the numbered streets in Minneapolis and Hennepin County carry on through Anoka and Isanti Counties, eventually reaching 417th Avenue North. To the south, the Minneapolis grid also extends into Dakota County, getting as high as 330th Street at the Rice County line, near Northfield.

Anyone know of any other instances of this phenomenon beside the ones I mentioned? I'm sure there are several other examples of that throughout the country.

In Metro Detroit there are the Mile Roads. The first one is 5 Mile Road which is Fenkell in Detroit. This is based on the intersection where Campus Martius Park is located (Woodward, Michigan, Fort, Monroe and Cadillac Square). This starts in Wayne County and goes into both Oakland and Macomb County as well continuing until 37 Mile Road in Macomb County.

Local people sometimes will refer to the Mile Road using just it's number such as, 8 and Middlebelt for 8 Mile and Middlebelt or 14 and Schoenherr for 14 Mile and Schoenherr. Pronounced SHANE-ER.

Manhattan's numbered streets go into the Bronx, and then into Yonkers by 5 feet (part of 263rd crosses the line).

Not sure if this counts, but Milwaukee numbers extend to eastern Waukesha, southeast Washington, and southern Ozaukee counties.  The catch is that Milwaukee uses straight numbers, but the other counties uses a grid system such as W145N7638 would be 7638 w/o the grid (the W145 means the 145th block west of the deviding line in Milwaukee.

Chicago's numbered streets extend beyond Cook County. Will and DuPage Counties are known to use them. Kendall County even has a few of the Chicago numbered streets

Although SLC's grid extends through various suburbs in all directions, the grid stops at the county line.

Unless you live in that section of Draper that extends into Utah County. Addresses there still follow the Salt Lake County grid, with numbers getting up into the 16000 S range. However, there are no SLC-based number-only streets outside Salt Lake County.

Elsewhere in Utah: the unincorporated Duchesne County grid centered in Roosevelt extends into much of western Uintah County. South Weber (Davis County) also has several numbered streets based on the grid centered in Ogden (Weber County).

Are there any rural examples of this?  That is, one county uses a neighboring county's rural numbering system for its rural numbering system?

Hamilton County, IN, continues Indianapolis' street numbering system for E-W streets/roads.

As for the rural/rural example, there's one but it's names instead of numbers. Marshall County, IN extends St. Joseph County's alphabetical tree-based naming system for N/S roads.

Chicago’s numbered streets extend beyond Cook County. Will and DuPage Counties are known to use them. Kendall County even has a few of the Chicago numbered streets

A minor nitpick, but having grown up in Kendall County, the numbered streets are disallowed from continuing into that county.  111th becomes Rance at the county line, 119th becomes Scotch at the county line, 127th becomes Simons, etc.  135th might be the one exception to the rule that managed to weasel its way over to Ridge Rd, 1/2 mile past the county line 

A few "xx Ave" north-south roads can be found in Will County, corresponding to Chicago's street grid.  The rural roads in DuPage, Kane, and Will Counties all are based on the Chicago street grid, allowing for the ordinal numbered streets to propagate into those counties (not that Kane really has any).

To add one to the list, Hammond in Lake County has some numbered streets based on Chicago's grid.

The Portland, OR numbering system extends westward into rural Washington County and eastward into Clackamas County (Portland is in Multnomah County).  The only exception is that most towns/cities opt for their own numbering/naming system, within their city limits, but the counties just base everything off of Portland's Grid.

The Portland, OR numbering system ...

I think you've confused another thread about house numbers with this thread about streets themselves that are numbered.  For example if Second Street goes beyond the city limits into the suburbs and rural areas, still called Second.

135th St was the one that caught my eye for Kendall.

Also, if/when 95th Street is ever actually extended all the way to US 30, which appears to have the ROW reserved (yes, it is also a Power Line corridor, but it appears also reserved for roadway), it would enter Kendall. Who knows, it might change names by then

I know road ROW is reserved to at least Eola. When I worked up that way, there were utility cabinets on Eola Rd that have addresses for 95th St =). Looking at the Aerial images it looks like close to the same width of ROW all the way to US 30

Oh geez, you mean that one you specifically mentioned in the post immediately before my reply?   

I'm lucky I manage to get my pants on in the morning, I swear........

Hey, it happens, even to the best of us.

No, I'm meaning that when you get 158 blocks west of the Willamette River, in Washington County, you are on 158th St.  If you are on SE 82nd St. in Portland, and cross out of the city, into Multnomah County, and then into Clackamas County, you are still on SE 82nd.  The street names and addresses both, extend beyond the limits of the city and into the county and adjacent counties.

Many counties in Iowa and Minnesota number their rural roads, such that they increment by 10 every mile. (These roads, I believe, correspond to the section lines that were drawn when the land was first surveyed, way back when.) In southern Minnesota, the numbering system for the north-south roads in Martin County, where Fairmont is located, extends east through Faribault and Freeborn Counties as well.

I've often driven with my family on I-35 between Des Moines and the Twin Cities to visit relatives in Minnesota. Just north of Albert Lea, I remember having seen a sign for 775th Avenue on a nearby road visible from the freeway. (Having looked at a map of the area last night, I learned that the roads in Freeborn County go as high as 900th Avenue, which runs along the Mower County line.)

In the Denver metro area, numbered east-west avenues begin just south of downtown starting at 1st and go north to 168th, thus covering Denver County, Jefferson County to the west/northwest, Arapahoe County to the east, Adams County to the north/northeast, and part of Broomfield County to the northwest.

Adams County has the most rural stretches and carries the number grid to its very rural eastern border. Arapahoe County carries the 6th Avenue moniker at least until Bennett.

Interestingly enough, Broomfield County partially continues the Boulder County grid as well which has numbered streets running north-south. The only duplicate number between the grids within the county is 120th Avenue here and 120th Street here. Broomfield has a third numbered grid of east-west numbered avenues beginning with 1st Avenue one block north of 120th Avenue. This is a much more localized grid and doesn't count for this thread as it doesn't leave its county borders.

Surprised no one has mentioned the statewide system for numerical street names in rural North Dakota: https://en.wikipedia.org/wiki/Burkle_addressing_system
