But sometimes a ruptured water main, street repairs, or the destruction from a major sto' '~r or earthquake provides unfortunate reminders of the infrastructure's significance. The product of centuries of technological development and decades of construction, maintenance, and management, the system has developed for the most part as separate and distinct power plants, roads, pipelines, and waste repositories, built and operated by a myriad of government agencies, independent authorities, and private corporations.

The NSF can make a great contribution to progress in ~hancing the nation's infrastructure by continuing to adopt this broad view and thereby fostering a truly interdisciplinary approach to infrastructure research. Infrastructure comprises both private- and public-sector elements, and current trends toward privatization of some modes while others are shifting toward greater government involvement make it difficult to state a sharp definition of "public." Nevertheless, "public" conveys meanings related to service to the public, public ownership or operation, and publicsector economics that can be used to guide—but not to constrain tightly— the scope of this infrastructure research agenda.

The federal government is the principal source of infrastructure research spending overall, but the level of effort varies substantially among infrastructure's principal functional modes. At the one extreme, highway research has long been reliably supported by budget allocations from federal and state gasoline tax revenues and is conducted in many government laboratories (federal and state)

Regardless of the institutional setting within which the NSF-sponsored infrastructure research is undertaken, a single, unified program announcement, spanning all areas of infrastructure research, will best convey the cross-cutting philosophy embodied in the committee's agenda. Investment in infrastructure research is well justified by valuable benefits to be gained: greater durability and enhanced performance for the physical infrastructure, the training of a new generation of infrastructure professionals, environmental protection, greater economic productivity, and improved quality of life for everyone who uses the infrastructure.

Over the 6ridge's 33-year life, the originally meager rip rap protection of the piers was gradually clispersed. No effective periodic assessment was made to warn of the deterioration of the rip rap, on the basis of which remedial measures could have been taken.
