Mobility Planning & Guidance

When we plan a construction or maintenance project, we must consider how our work may impact the movement of people and good through the area.

By evaluating mobility during our planning process, we will:

  • Maintain and enhance work zone safety.
  • Minimize detours and delays for travelers and the freight industry.
  • Minimize permanent and temporary freight size and weight restrictions.
  • Maintain critical routes to ensure freight can move through the state unimpeded.
  • Engage mobility stakeholders to find solutions and minimize impacts.

Project Requirements

The Highway Mobility Operational Notice — PD16 provides guidance on implementing key ODOT mobility policies, processes, roles and responsibilities related to project delivery. This guidance applies to all state and federally funded projects on state highways, at the project development stage through construction. This operational notice is consistent with the policies and proce​dures contained within the more detailed ODOT’s Mobility Procedures Manual​, the accepted authority for mobility policy for the Agency.

Key policy considerations include:​

  • Identification of Mobility Issues.
  • Communication and Coordination.
  • Temporary Restrictions.
  • Permanent Restrictions.
  • Transportation Management Plan.
  • Contract and Design Considerations.
ODOT Policy PMT 06-01​ requires the Department to work collaboratively with, and minimize the impact where possible, to the motor carrier industry and local government when it becomes necessary to restrict the allowable size and weight of loads on the state highway system in order to maintain safe travel.​

The Project Mobility Consideration Checklist is a tool to help identify potential impacts to freight and traffic mobility in the development phase of a project.

  • During planning and design phases of a project, the project team must provide for stakeholder and ODOT Mobility Advisory Committee input. The Mobility Team will help facilitate conversations through email or meetings.
  • The ODOT Statewide Mobility Team requires at least 15 business days to review mobility consideration checklists for projects that have already been shared.
  • If the project has not b​ee​n shared with stakeholders prior to checklist submission, more time may be required.
  • A TMP and Decision Tree must be submitted with the checklist.
  • Any potential ORS 366.215 impacts must be shared and approved before signing the checklist. More time is needed for review and additional information is required. See Guidance for Implementation of ORS 366.215.
  • Off-system projects that create a mobility impact on the state system must also comply with PD-16 and this checklist.
  • Prior to PS&E, the Statewide Mobility Program manager must sign all mobility consideration checklists for highway projects that impact freight and traffic mobility. Project leaders and local agency liaisons with projects, both on-system and off-system that have no mobility impacts, should check the "no mobility impacts" box and sign the checklist.
  • Mobility Program signature is not required for a "no mobility impact" project before submitting it with the PS&E package.
  • The TMP should contain all information needed to sign the mobility consideration checklist.

Changes to Project Mobility Consideration Checklist

Before making changes during construction that have the potential to adversely affect mobility or run counter to previous agreements, the Project Manager:

  • Must discuss proposed changes with the contractor, region mobility liaison and any relevant region resources to discuss proposed changes to determine if the change is warranted and supported by the region.
  • Engage the mobility team to discuss and get agreement with the potential changes before any agreements are made with the contractor, if supported by the region.
  • Document ODOT Statewide Mobility Program and trucking industry support of any potential new restrictions and provide a copy of the documentation to the region mobility liaison.

Leadership Direction for Changes to Mobility Consideration Checklist

​A TMP is a documented set of coordinated transportation management strategies used to manage the temporary work zone impacts of construction projects. For more information, a TMP Project Level Guidance Manual is available.


  • Minimize disruptions to motorists, the freight industry and communities.
  • Maintain public and worker safety without compromising the quality of work being performed.
  • Address growing congestion on many roads and an increasing need to perform rehabilitation and reconstruction work.
  • Provide guidance to ODOT designers on how to develop project level TMP documents for projects. The project level TMP guidance document has been adopted by ODOT and applies to all projects in conjunction with the goals of the FHWA rule on Work Zone Safety and Mobility 23 CFR 630 Subpart J.

  2. Traffic operations strategies to better manage traffic before and during construction work.
  3. Public information campaigns notify road users of the upcoming construction project, its impacts and their transportation alternatives.
"Simplified" Version TMP Components
  1. A Traffic Control Plan.
  2. ​Thorough documentation of all related design and construction staging decisions.

Information needed for the Freight Mobility Section of the TMP

  • Critical route pair information.
  • Detour route information. If on a local road, list the following:
    • Who approved it?
    • Describe truck modeling.
    • Will the detour route allow oversize loads that are currently allowed on the restricted route?
    • Are there any restrictions on the detour route?
  • Can oversize loads be accommodated through the work zone by moving barriers and equipment out of the way and waving loads through with a short delay?
  • Is advanced noticed required?
  • Are crossovers used? If so, will traffic travel under structures?
  • When lane closures are used, describe how much width is available for traffic between barriers.
  • Is the work zone on a tangent or curve?
  • Describe any ramp closures.
    • Which on and off ramps are closed?
    • How long will the closure last?
  • Specify hours of operation for the project.
    • ​Is the work done at nighttime, daytime or both?
    • Is weekend work allowed?
    • Are there windows of opportunity for loads to get through?

Highway restriction notices are required whenever construction or maintenance work will close or restrict a state highway or ramp. Visit Oregon Travel Restrictions and Guidelines​ for information on submitting restriction notices.
