SUPPLEMENTARY INFORMATION: The Illinois Department of Transportation
requested a temporary deviation for the Hardin Drawbridge, across the
Illinois Waterway, mile 21.6, at Hardin, Illinois to remain in the
closed-to-navigation position for a two and one half day period while
the main gear case is replaced. The closure period will start at 7 a.m.
on or about April 3, 2012 and end at 7 p.m. on April 5, 2012.
    Once the existing gear case is removed, the lift span will not be
able to open, even for emergencies, until the replacement gear box is
installed.
    The Hardin Drawbridge currently operates in accordance with 33 CFR
117.5, which states the general requirement that drawbridges shall open
promptly and fully for the passage of vessels when a request to open is
given in accordance with the subpart.
    There are no alternate routes for vessels transiting this section
of the Illinois Waterway. The Hardin Drawbridge, in the closed-to-
navigation position, provides a vertical clearance of 25.9 feet above
normal pool. Navigation on the waterway consists primarily of
commercial tows and recreational watercraft. This temporary deviation
has been coordinated with the waterway users.
    In accordance with 33 CFR 117.35(e), the drawbridge must return to
its regular operating schedule immediately at the end of the designated
time period. This deviation from the operating regulations is
authorized under 33 CFR 117.35.

    Dated: March 22, 2012.
Eric A. Washburn,
Bridge Administrator, Western Rivers.
