Blood urea nitrogen (BUN) test. Overview. A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys and liver are working. A BUN test measures the amount of urea nitrogen that's in your blood. 1  Your liver produces ammonia â which contains nitrogen â after it breaks down proteins used by your body's cells.  The nitrogen combines with other elements, such as carbon, hydrogen and oxygen, to form urea, which is a chemical waste product.
Shortly after the Turner Turnpike was built in 1953, the Oklahoma Turnpike Authority proposed other toll roads including one to be built from Oklahoma City north to the Kansas border near Braman to tie in with the southern terminus of the Kansas Turnpike at the state line.
In 1954, Governor Thomas E. Dewey (1902-1971) approved the construction plan for the large highway joining Manhattan to the east of Long Island, at a cost of $500 million. The highway was originally designed for a daily capacity of 80,000 vehicles. By 1958 construction on both the Horace Harding Expressway, already commonly referred to as the Long Island Expressway and the first section of the Expressway in Nassau County was completed.
