In the mid-1990s, the Dutch economy grew at a pace of 3 to 4 percent annually (CBS, 2009). The use of the country's major infrastructure increased accordingly, and the urban areas in the western part of the country, the Randstad, continued to expand to meet the soaring housing demand. After decades of state intervention, the government started to loosen its grip on local and regional urban development. The government's policy on spatial planning shifted away from the concept of planning new towns to focus on more compact urban development (compacte stad). The policy reasoned that a compact city would have a smaller environmental footprint because of more effective land-use and shorter daily travel distances. With its Fourth Report on Spatial Planning (VROM, 1988: Vierde Nota) and the additional VINEX-report (VROM, 1993: Vierde Nota Extra), the Ministry of Spatial Planning, Housing and the Environment no longer seemed to dictate that one solution that fits all. Rather, it sought to implement developments that suited the regional territorial characteristics and the preferences of the concerned authorities. Thus, Utrecht ended up with the largest VINEX-development in the Netherlands. In fact, Utrecht is the fourth largest city by population in the country, after Amsterdam, Rotterdam and The Hague.

Although the concept of the 'compact city' may be simple, it had deep implications for the relation between infrastructure planning and town planning. Back in the seventies and eighties two major new town developments were built south of Utrecht to house its expanding population. The physical distance between the mother city and its new towns allowed the unobstructed expansion of the national motorway network. In the nineties Utrecht preferred a development that kept its inhabitants close by so they would remain bounded to Utrecht, both economically and socially. The development of Leidsche Rijn with a projected 30.000 housing units sought a close physical relationship with the mother city. For the first time the extending city and the expanding motorway network became at odds with each other. The area between Utrecht and Leidsche Rijn left little space to accommodate a wider A2 motorway and its environmental impact. Encapsulating the A2 motorway in a two kilometre long tunnel was proposed as the most suitable way to integrate the road in the new urban district. With no effective regulation in place and no similar practice to fall back on, the Leidsche Rijn land tunnel broke ground to allow the use of motorway tunnels for a new and promising application: environmental and spatial integration of motorways in urban areas. This chapter focusses on the struggle and trade

Leidsche Rijn: Balancing the Compact City with the Randstad Motorway Network 25

This chapter deals with the growing tension between the necessity to widen the Randstad's motorway network and its urban footprint. It poses the question how to integrate large scale infrastructure in urban areas. This design/engineering/planning task requires a multidisciplinary approach, combining insights drawn from urban and spatial planning, civil engineering, safety assessment, environmental impact assessment and governance.

Because most foreign readers aren't familiar with the topography and the spatial development of the western part of the Netherlands three key areas are highlighted first: the Randstad, the Green Heart and Leidsche Rijn. This sets the stage for explaining why Leidsche Rijn is a good indicator for the changes occurring in the leading concepts of urban planning, spatial planning and infrastructure planning in the Netherlands. It allows the discussion of the main concept of the Leidsche Rijn in order to explain why the city wanted to integrate the A2-corridor in the urban development. That integration had deep consequences for the physical shape of that road as it required the construction of a major road tunnel. As soon as the concept for a tunnel was embraced by the local and regional governments the deal started to unravel under pressure safety concerns, voiced by the national government. The safety of the users of the tunnel and the safety of those that would live or work next to it seemed at risk. At this point the chapter moves into an interdisciplinary area where only a few specialist speaks each others professional language. Due to a lack of mutual understanding between politicians, urban planners, safety assessment officers and transport planners the project moved in to a deadlock which took

The storyline is based on the review of many of the relevant policy documents and plans written in the Dutch language on this matter, on in depth interviews with key players in the process and the various environmental and safety assessments. The final form of this

Utrecht is one of the four Dutch cities that jointly constitute the Randstad. The Randstad is the framework commonly used to describe the densely populated western part of the Netherlands. In the mid 1960s that Randstad was discovered by academics from the Anglo-Saxon world as an alternative model for metropolitan growth. For London, in particular, struggling to contain its large continuous urban area, by the so-called Green Belt, the Randstad seem to demonstrate that a large urban population could be organised in a networked polycentric configuration, and function well at the same time. That idea appealed to writers like Gerald L. Burke (Burke, 2006) and Peter Hall (Hall, 1966, 1977, 1983). The Randstad was seemingly less congested than a classic metropolis and possessed

The simple concept of a large green area surrounded by a ring shaped conurbation settled quickly in the minds of students, practitioners and academics alike. It also helped to place Holland on the map and that seemed necessary. In 1966 Gerald L. Burke already noted that although The Netherlands is known for its city planning, "less widely known are the policies of regional planning which have been developed in the Netherlands since World War II"
