The new 40-foot wide bridge consists of 10 four foot by two foot concrete planks bolted together. Between the planks a small crevice will be left to provide bat roosting areas. Adding bat roosts will not add appreciably to the cost of construction. Bats like to roost in concrete bridges because of the fairly constant temperature, darkness of crevices, close proximity to food sources, and relative seclusion. President Kennedy first proclaimed National Public Works Week to remind us each year of the many ways public works contribute to our quality of life.
Public works is a proud profession of community service.
Public works are an investment of tax money in our own future. They provide the physical infrastructure we must have for the social and economic development of American civilization. They make everything possible, from villages and cities to commerce and industry. And private sector companies furnish the equipment, materials, and many of the services needed to build our public works. These projects are a crucial part of the local and national economy.
