TITLE 33--NAVIGATION AND NAVIGABLE WATERS
CHAPTER 11--BRIDGES OVER NAVIGABLE WATERS
SUBCHAPTER I--GENERAL PROVISIONS
Sec. 494. Obstruction of navigation; alterations and removals;
lights and signals; draws
No bridge erected or maintained under the provisions of sections 491
to 498 of this title, shall at any time unreasonably obstruct the free
navigation of the waters over which it is constructed, and if any bridge
erected in accordance with the provisions of said sections, shall, in
the opinion of the Secretary of Transportation at any time unreasonably
obstruct such navigation, either on account of insufficient height,
width of span, or otherwise, or if there be difficulty in passing the
draw opening or the drawspan of such bridge by rafts, steamboats, or
other water craft, it shall be the duty of the Secretary of
Transportation after giving the parties interested reasonable
opportunity to be heard, to notify the persons owning or controlling
such bridge to so alter the same as to render navigation through or
under it reasonably free, easy, and unobstructed, stating in such notice
the changes required to be made, and prescribing in each case a
reasonable time in which to make such changes, and if at the end of the
time so specified the changes so required have not been made, the
persons owning or controlling such bridge shall be deemed guilty of a
violation of said sections; and all such alterations shall be made and
all such obstructions shall be removed at the expense of the persons
owning or operating said bridge. The persons owning or operating any
such bridge shall maintain, at their own expense, such lights and other
signals thereon as the Commandant of the Coast Guard shall prescribe. If
the bridge shall be constructed with a draw, then the draw shall be
opened promptly by the persons owning or operating such bridge upon
reasonable signal for the passage of boats and other water craft.

Prior Provisions
Act July 5, 1884, ch. 229, Sec. 8, 23 Stat. 148, relating to
authority of Secretary of War to require owners of bridges which
obstruct navigation to relieve the situation or be penalized, was
probably omitted from the Code as superseded by this section and section
495 of this title, which by section 498b of this title were made
applicable to bridges authorized prior to March 23, 1906.
Section would seem to supersede a provision of act Aug. 7, 1882, ch.
433, Sec. 1, 22 Stat. 309, which read as follows: ``That all parties
owning, occupying, or operating bridges over any navigable river shall
maintain at their own expense, from sunset to sunrise, throughout the

year, such lights on their bridges as may be required by the Light-House
Board for the security of navigation: and in addition thereto all
persons owning, occupying, or operating any bridge over any navigable
river shall, in any event, maintain all lights on their bridge that may
be necessary for the security of navigation.''
