Municipalities within Gauteng may also support the elaboration of district spatial development plans for each of the planning districts within a metropolitan area, but these tend to be much more detailed plans on specific zoning and development decisions in the near term. Most of the major infrastructure projects in the province have been achieved through intergovernmental co-operation, and this continues to be strengthened and refined. Positive aspects of co-operative governance include intergovernmental plans and planning structures to give effect to the Programme of Action, as well as the implementation of a range of key intergovernmental delivery projects.9 Amongst the most important intergovernmental projects is the development of Gautrain, the multi-billion rand fast-rail link, which connects the major centres of Tshwane and Johannesburg with the O.R. Tambo International Airport in the eastern part of the region. While provincial government negotiated the major portion of government funding for the project, as well as the private-sector investment component, provincial and local government collaborated closely on the design of stations and station precincts.
