Guldi seeks to reclaim the lost role of the State in the history of the British road network prior to the 20th century. This is a history of the development of the “infrastructure state,” something she argues has not been fully recognized or appreciated. The predominant role that private enterprise played in the later nineteenth century has overshadowed an early period; a full century ending in the mid 1830's when the British state, through increasingly centralized means, created a substantial and robust national road network where none had previously existed. In order to convert a scattering of locally-funded turnpikes and a sparse network of military roads built to solidify British control of Scotland into a much more rationalized network serving civilian and economic needs, visionary “centralizers” found the tools—physical, fiscal, and rhetorical—to sway political opinion towards their expansionist, nationalizing ends.
In this light, Guldi finds that the real accomplishment of long-celebrated heroes of civil engineering wasn’t their technical innovations in road- and bridge-building, but their persuasive and managerial talents. Creating a national road network was less a triumph over the physical environment than over parochial interests and deeply-rooted notions of British liberty. The genius of MacAdam, then, wasn’t the technique of road paving named for him (and Guldi notes that he should be regarded as a popularizer, not innovator, of his namesake “macadamized” roads). Rather, MacAdam developed methods of enforcing standardization without reliance on on-site experts, while managing a large, unskilled workforce.
In the end, opponents to the newly created national road network won the political battle within a few short decades of the ‘centralizers’ victory; the localization movement succeeded politically but the cost to British roads and to poorer regions of Great Britain was high. In the early 20th century, the pendulum would swing back towards centralization—in Britain and elsewhere—and then libertarian opposition to the concept of the ‘public good’ would make yet another comeback at the end of the century—an era we are still living through. Lobbying efforts by telecommunications interests to essentially turn the internet into a “toll road” of sorts is part of that same backlash.
