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.
THE TURNPIKE OPENS TO ACCOLADES: The entire 118-mile length of the New Jersey Turnpike took 25 months to construct, at a total cost of $255 million. The first 44-mile-long stretch, from EXIT 1 in Carneys Point Township north to EXIT 5 in Westampton Township, opened on November 5, 1951.
