One Mile (Part 1 of 4)

Core idea

One Mile is the book's most famous topic and Caro's deepest examination of what Moses's method cost. Caro narrows the lens from 627 miles of roads to one mile of the Cross-Bronx Expressway, and to one neighborhood — East Tremont — that the mile destroyed. The first part introduces the neighborhood as it existed in 1953: a working-class, mostly Jewish Bronx community settled by garment workers and their descendants, with synagogues, butcher shops, and three generations living within blocks. By the time the topic is done, the neighborhood will be gone.

Why it matters

East Tremont in 1953

East Tremont was a stable working-class Jewish neighborhood, settled in the 1910s and 1920s by garment workers who had moved up from the Lower East Side. By 1953 it had three generations of residents, dozens of synagogues, a thriving commercial strip on Clinton Avenue, and rents low enough that retired residents could afford to stay. It was the kind of stable urban neighborhood mid-century planners said could not exist — and that the Cross-Bronx would destroy.

Why Caro narrowed to one mile

The Cross-Bronx Expressway is seven miles of one of thirteen Moses expressways. Caro could have written about all 627 miles in aggregate. Instead he narrowed to one mile, one neighborhood, one decade. The narrowing is the topic's technique: the abstraction (627 miles, 500,000 displaced) becomes legible only at the granularity of the synagogue on this corner, the butcher shop on that one, this family that has lived here for forty years.

Practical application

Example

Investigative journalism on the opioid crisis has used the same narrowing — from aggregate overdose statistics to single counties to single families. The narrowing produces political traction the aggregates could not. Caro's One Mile is the mid-century template.
