“Divided by Design” uncovers the profound impacts of transportation decisions on socio-economic and environmental landscapes, revealing a legacy of division that continues to affect marginalized neighborhoods.

A Legacy of Division: Exploring the profound impact of highway construction on urban communities

Transportation projects, especially highways, were once celebrated as symbols of progress and modernization. However, their legacy is far more complex. Historically, these projects were executed with scant regard for the communities they disrupted, particularly those of color. This report uncovers the systematic division and disenfranchisement resulting from these decisions and highlights how the negative impacts persist today.

The Report: Part I

Part I examines the damage and inequities deliberately created by and in the federal transportation program from ~1950 onward. It concludes with a unique analysis of both an unbuilt and built highway segment within Atlanta and Washington, DC to quantify what was lost, who bore the brunt of the damage, and what could have been lost with highways that were never built.

The Report: Part II

Part II examines our current transportation program to demonstrate how the programs, standards, models, and measures have their roots in the previous era and exacerbate inequities—whether intentional or not.

The Report: Part III

Part III outlines what needs to change—concrete steps we can take to fundamentally reorient the program around unwinding those inequities.

Read our final words aimed at reversing past harms and advancing more equitable transportation policies.
