Oregon Highway Restriction Notices

Purpose of Highway Restriction Notices

Contractors; Resident Engineers; Project Managers and ODOT Region Mobility Liaisons must complete an online Highway Restriction Notice Form whenever construction or maintenance work will either close a state highway or ramp; or restrict the width, length, height or weight of trucks within a work zone on a state highway.

Submitting Highway Restriction Notices allows the ODOT Over-Dimension Permit Unit to ensure work zone safety and help motor carriers hauling oversize loads plan their trips by:
For questions regarding the highway restriction notice form or the restriction notice process, please contact our OD Restriction Notices Team. See our Statewide Mobility Program web page for additional information regarding standards and processes that help ODOT.

Do I need to turn in a Highway Restriction Notice?

For all project work (excluding maintenance), a restriction notice is not needed if work activity meets ALL of the following requirements (per Chapter 5 of the Mobility Procedures Manual). For maintenance work, refer to Activity 1 of ODOT’s Maintenance Mobility Requirements.
  • Project staff can safely accommodate all unannounced oversize loads through the work zone with minimal delay by moving cones, equipment out of the way. Contact the Mobility Team for accommodation requirements on mainline interstate highways.
  • The minimum width maintained for a single open travel lane is 22 feet or greater between barriers, including the travel lane plus any paved shoulder.
  • The minimum width maintained for traffic is 28 feet or greater for two travel lanes for one way traffic.
  • The minimum width maintained for traffic is 28 feet or greater for two travel lanes for two-way traffic with no traffic separator/candlesticks being used on the centerline.
  • No lane shifts or lane closures will divert traffic into a travel lane with less vertical clearance underneath structures.
  • Traffic is not detoured onto a secondary route.
  • Ramps are not closed.
  • No length restriction is needed.
  • No weight restriction is needed.
For contractors who are still required to submit a restriction notice (per contract specifications 00220.03(a) Work Zone Notifications), the contractor can submit the form and indicate that no restriction is needed in the “Explanation of Work” field (provided all of requirements described above are met).

How much notice is required?

Regardless of the type of restriction, contractors are required to submit the Highway Restriction Notice Form 35 days before work begins to allow time for the Over-Dimension Permit Unit to review and submit the form to the Mobility Team.
  • The Mobility Team must receive restriction notices 14-28 days prior to work beginning.
  • The amount of notice needed is based on the location and type of restriction.
See chapter five of our Mobility Procedures Manual for specific notification requirements. Typical requirements are:
  • 14-day notice — Ramp closures to/from a local road.
  • 28-day notice — Full highway closures and traffic is being detoured.
  • 14-28 day notice — Width restrictions due to lane closures or reduced roadway width. See Daytime and Nighttime Width Restrictions.
  • 28-day notice — Ramp closures to/from a state highway.
  • 28-day notice — Weight restrictions affecting annual oversize permit holders.
  • 28-day notice — Length restrictions affecting annual oversize permit holders.

Width Restriction Notice — Daytime and Nighttime

The amount of notice needed is based on the route, the width and whether the restriction is during the day or night.
  • Use the following Freight Mobility Maps to determine the color of route the restriction will be on.
  • Use the tables below to determine the amount of notice required.
  • Use this Sunrise/Sunset Calendar to determine if the allowable lane closure hours and/or width restrictions occur during the daytime or nighttime requirements.
Daytime width restrictions occur from ½ hour before sunrise to ½ hour after sunset.

Resources for Submitting Highway Restriction Notices

ODOT District and Regional Information / Maps / Mobility Liaisons

Districts
The District Manager or their designee may require restrictions (e.g., emergency declarations) as necessary to:
  • Protect the safety and convenience of the traveling public.
  • Protect any highway or section from damage.
  • Avoid conflict with highway construction or repair projects.
  • Cope with other local traffic conditions.
Regions
ODOTs Regions manage mobility on all of their maintenance activities and construction projects. Each Region Manager has appointed a Region Mobility Liaison who is the point of contact for region staff and the ODOT Mobility Policy Committee.
Mobility Liaisons
Mobility Liaisons are also the primary resource for planners, project team leaders, resident engineers, managers in Region and District offices, Mobility and the Over-Dimension Permit Unit for assistance with meeting mobility goals and the restriction notice process. A current list of Region Mobility Liaisons is found on the Statewide Mobility Program web page.

See Chapter 2 in the Statewide Mobility Program for additional information about District Manager and Mobility Region Liaison responsibilities.
