extended to the west, roughly along the same alignment proposed in 1970. In 1982, the freeway portion was extended a little more to the west, nearly to the current western terminus of I-516. In 1985, the entire highway from its then-current western terminus at Burnsed Blvd to Montgomery Street was designated as I-516. The freeway portion was extended westward to the interchange with SR 25 (Burnsed Blvd) and eastward to the current eastern terminus.
