SPECIAL CIRCULAR BRIDGE SIGNS.
(5) All bridges not having the full NATO sign should have one
of the circular signs. Normal signs include those for one-way bridges and
those for two-way bridges.
One-way bridges will have the bridge
classification in black numerals on the yellow circle. These are normally
found on bridges less than class 50. A two-way bridge sign will be divided
in half vertically.
On the left half of the circle will be the two-way
classification, and on the right the one-way.
