Typical Gate Signing With Object Markers (OM) for One-Lane Roads If motorized or nonmotorized use (such as bicycles) occurs behind a gate, the back side will require sign-ing also. Size of barricade markers depends on approach speeds. Travel management signing: if road use is restricted with an order, a travel management sign should be mounted on the gate or on a post next to the gate. For seasonal restrictions, the travel management sign should be mounted on a post next to the gate so it is visible when the gate is open.

Work Zone Identification Sign Work zones include construction, maintenance, and logging operations.

* See page iii for placement exceptions.

All temporary traffic control devices shall be removed as soon as practical when they are no longer needed. When work is suspended for short periods of time, temporary traffic control devices that are no longer appropriate shall be removed or covered.

Work Zone Sign (temporary support)For short-term, short-duration, and mobile conditions only. Signs should be constantly maintained for cleanliness, visibility, and correct positioning because they are moved frequently.

Do not mount on trees or other signs. Do not locate on sidewalks, bicycle lanes, or areas designated for pedestrian or bicycle traffic.

Signs mounted on portable supports may be placed within the roadway if necessary. Signs may be mounted on or above barricades.

Road Closed Sign This sign marks roads that have been closed to all motorized and nonmotorized traffic (except authorized vehicles) because of a tem-porary emergency, construction and maintenance activities, or spring breakup. It is not to be used on a gate or closure for sea-sonal or long-term road restrictions.

When no turns are intended, stripes should be positioned to slope downward toward the center of the barricade. Barricade stripes should slope downward toward direction which road users must turn.
