The New York Times posted an interactive graphic last year showing how Manhattan’s street grid grew – street openings by year.

I came across it recently and started wondering when the streets were created in Mamaroneck village, where I live. So, I took a look at some old maps and put together interactive Google maps showing which streets existed by 1867, 1881, 1910, 1929 and those added since 1930.

Take a look at the maps below to see the pattern of development. Click on a street for more information about it. You can also zoom in for a closer look.

First, take a look at today’s streets that were around in one form or another in 1867, in red:
Mamaroneck and Rye Neck streets, 1867

Things to note for 1867:
• Just a few local streets, mostly downtown and in Washingtonville, including Mamaroneck Avenue, then called Winfield Avenue; Halstead Avenue, then called Railroad Avenue; and Mount Pleasant Avenue. Some Washingtonville streets had different names, too, including Center Avenue, then called Clay Street, and Waverly Avenue, then called Franklin Avenue, according to the maps.
• One road each to two sections that jutted out into Mamaroneck Harbor – Orienta Avenue and Taylors Lane.
• Major roads to other towns: Boston Post Road (called Main Street in downtown Mamaroneck then), Harrison Avenue, West Street, Rockland (then Rockdale) Avenue and White Plains Road.
• The railroad depot was at the west side of Mamaroneck Avenue – at the intersection of Mamaroneck (then Winfield) Avenue and Mount Pleasant Avenue, along with a hotel and a feed store. The present railroad station house (now becoming a restaurant) east of Mamaroneck Avenue dates to 1888.
• The Depot School, a public school, was in the triangle created by the Mamaroneck-Mount Pleasant intersection in 1867. The old schoolhouse now on display in Harbor Island Park sat in that triangle from 1816 to 1855.
• Mamaroneck village wasn’t incorporated until 1895, so early maps refer to it as Mamaroneck and Rye Neck or just Rye Neck.


By 1881, the village was spreading out from the downtown along the route of the railroad, and Orienta was filling in.

Red: Streets existing as of 1867.
Green: Streets added between 1868 and 1881.

By 1910, the development extended farther out from the downtown and in Harbor Heights off Mamaroneck Avenue, with most of the present-day streets in existence by then, although certainly not all built up. A bit more of the land along upper Mamaroneck filled in by 1929, then a few more streets since.

If you’ve got more details on the history of particular streets, or corrections on the years, let me know and I’ll add them to the notes for that street.
