This chapter examines megaproject design and planning in two “shrinking cities” – Philadelphia, PA and Detroit, MI – and concludes that megaproject “metastasis,” or repeated expansions into surrounding urban fabrics, is promoting the reduction of downtown into a series of self-contained enclaves. While political coalitions are constructing megaprojects, or large public works and/or single buildings, in cities around the world, in the United States, single-building megaprojects motivated by “growth coalitions” of public and private development actors have proliferated in downtowns since 1990. The urban design impacts of these megaprojects on the surrounding urban fabric have been little studied. Data on the institutional history, physical expansion, and relationship of the megaprojects to the urban fabric is combined with a qualitative analysis of megaproject theory and its application to the American condition, as well as to the political economy of development in American shrinking cities. The chapter concludes that megaprojects such as convention centers and casinos tend to expand inexorably once they are introduced into the American downtown. This metastasis results in the destruction of existing older buildings and street networks, the consolidation of street blocks into ever-larger superblocks, and the eventual physical restructuring of downtowns into enclaves of older fabric amidst clusters of megaproject superblocks. Applying Jacobs’ (1992) theory of “moral hybrids” between “commerce and politics” to megaproject metastasis, the chapter argues that while megaprojects may be inevitable in American downtowns, they should be sited away from active, small-scale urban fabrics to reduce the negative impacts of future metastases. The chapter takes a design-oriented perspective on a phenomenon that is almost always understood from a political economy perspective alone. Megaprojects are significant physical entities, and the chapter clarifies their physical impacts on the urban fabric while indicating urban design policy directions to reduce these impacts in future.

The chapters by Joo, Gerardo del Cerro Santamaría, and Bunnell have shown that UMPs go beyond the local scale regarding development, implementation, and consequences. In fact, as they argue the projects in South Korea, Bilbao, and Kuala Lumpur obey a logic of reterritorialization à la Brenner, whereby the regional or national state actively participates in urban development by designing urban policies and projects which, in turn, exhibit political, economic, and visual dimensions going beyond the frontiers of the urban realm. This tendency has implications for the role of local politics in UMPs. Local political conditions (e.g., a housing shortage or a desire for global visibility) play a prominent role in the implementation of UMPs, as shown by the Bundang and Ilsan new towns in South Korea as well as Bunnell´s recounting of the reimagining of Kuala Lumpur. In Korea, strong central government control over the real estate market led to addressing the housing shortage and preventing real estate speculation; the chronic housing shortage, with the increased economic power of individuals, resulted in distinctive advance-sale and dual-pricing systems for new apartment units. The huge unmet housing demand in Korea during relative economic prosperity quickly filled Bundang and Ilsan’s housing units with new residents, contributing to the new towns’ successful outcomes.

This chapter discusses the combination of structure plans and urban megaprojects. It shows the characteristics and shortcomings of this combination in different urban contexts, in Western as well as in emerging countries. The chapter draws on case studies of megaprojects and urban planning processes in different cities: Abu Dhabi, Milan, and others. This chapter suggests that the tensions between branded megaprojects and structure plans are not due only to economic, planning, and political constraints. The publicly stated rationale of this combination is to trigger and harness the real estate market in order not only to create private revenue, but also to contribute to the overall city development. In many cases, this rationale induced significant changes not only in terms of architectural design and financial arrangements of individual projects, but also in terms of the urban structure. Reflecting over current global trends in urban development, these findings seem relevant both for reconsidering the roles of architectural branding and the weakening of large-scale urban planning devices in Western cities and for allowing emerging countries to learn from past experiences in this field.

The aim of this book is to understand the causes and consequences of new scales and forms of territorial and spatial restructuring in a context of accelerated globalization by focusing on a diverse array of urban megaproject developments that, in various forms and with various objectives, are transforming the global urban landscape at the outset of the 21st century. The contributions to this volume explore the architectural design, planning, management, financing, and impact of urban megaprojects, as well as the social actors and innovations driving them. The contributions also articulate the various socioeconomic, political, and cultural causes and consequences of UMP development, thus providing a context to understand the reconfiguration of urban spaces in the new millennium.

This chapter examines the physical embodiment of “conflict globalization” in the Afghan Ring Road megaproject by illustrating the Road's ability to produce close connections between localized and transnational powers while bypassing the Afghan state entirely. A multi-scalar spatial case study of megaproject development is utilized in this chapter. It encompasses a historic and current analysis of the interaction of the Afghan Ring Road's form with local, state, and transnational political economic structures. The chapter argues that the international nation-building strategy in Afghanistan constitutes a “mega-megaproject,” a package of reforms that relies on physical transformation of Afghan infrastructure to win the trust of the population. It uses the Afghan Ring Road to examine the ways in which even preexisting structures have been modified to fit into this megaproject-based system. It also examines the scalar implications of the Afghan Ring Road megaproject using examples of economic benefit to local militias and regional geopolitical energy interests. The chapter provides a starting point for further research on megaprojects’ role in mediating the countervailing forces of “nation-building” strategies and globalization. This chapter examines issues that constitute a critical component of the ongoing, multinational attempts to build a functioning Afghan state through global intervention.

The purpose of the chapter is twofold. First, it discusses the causes and characteristics of the current proliferation of rail station area redevelopment megaprojects around the globe, revealing them to be an important subset of the new generation of megaprojects discussed in this volume. Second, it offers a detailed and timely account of recent struggles surrounding “Stuttgart 21,” a massive, hugely controversial rail station redevelopment megaproject in Southern Germany, drawing lessons from the controversy over Stuttgart 21 for urban megaprojects more generally. This study is a qualitative case study analysis that involved interviews and document analysis. The experience of “Stuttgart 21” validates previous criticisms of megaprojects regarding transparency and public accountability in decision-making, environmental challenges, and cost-overruns. The political conflicts over “Stuttgart 21” are intimately tied to fundamental disagreements over future urban development and transportation policy, the costs and benefits of multibillion Euro megaprojects, and related democratic decision-making procedures. Rail stations emerge as an important, as-of-yet underexplored subset of urban megaprojects. Rail stations, especially those serving new high-speed rail corridors, are crucial development nodes within complex postindustrial urban–regional restructuring processes. But they also have a distinct character and historical identity. As the mass protests in Stuttgart show, they also clearly serve important identification functions in citizens’ lives.

Using the case of a failed airport project in metropolitan Mexico City, this chapter explores the political and economic reasons for urban megaproject failure. It examines the nature of the oppositional alliances; the larger political, economic, institutional, and spatial conditions under which these alliances were forged; and how they forced project proponents to abandon a planned megaproject. In searching for the factors responsible for project failure, the study employs theories of political party competition, bureaucratic–institutional conflict, and social movements. It uses qualitative and historical analysis to focus attention on divisions within and between the political class and citizens driven by democratization, decentralization, and globalization. The case suggests that the historical and institutional legacies of urban and national development in Latin America have created bureaucratic ambiguities and tensions over who is most responsible for major infrastructure development in countries experiencing democratic transition. The failure to successfully build the Mexico City airport megaproject reflects a precarious transitional moment in the country's political and economic development as much as the validity of claims against the project itself. If planners can better situate megaproject development in the context of changing institutional relations between citizens and the state, they may be better able to find common ground.
