Equation Variables:
D = Distance in feet from the near edge of the near approach traffic lane to either (a) the back of
pier, when the pier is located inside the Setback Distance or (b) the Setback Distance, when the
PPB
pier extends to or goes beyond the Setback Distance. For left side piers on two-way undivided

Pier Protection Barrier
intersection with the departure line. For left side hazards on two-way undivided facilities, d is
