Maintenance and Operations


The Goal: Keep ODOT roads open through maintenance, monitoring, repair and preservation of system assets.  


ODOT employess clearing debris off road after storm while traffice drives past.  
We work to keep interstates and highways open and accessible so people and freight can get where they need to go. Accordingly, we perform services such as snow and ice removal, clearing debris that can otherwise cause flooding, removing rockfall and landslide debris, and clearing lanes after traffic incidents. Part of ensuring roadways remain open also includes keeping roads, bridges, and other assets in good repair. When bridges are not maintained, for example, they cannot carry heavy trucks – forcing freight to take long detours. Preservation and maintenance functions are thus key to supporting customers – the traveling public – get where they need to go safely and efficiently.  

Services by maintenance staff help keep roads open

  • ODOT has about 1,300 full-time employees across Oregon who perform essential services needed to maintain, monitor, and repair the transportation system. They work 7 days per week, 365 days per year in all conditions to keep roads open and travelers safe.

Lanes are opened quickly after a crash or other incident

  • Every minute a highway or interstate lane is blocked by a crash results in 4 minutes of travel delay. 
  • Most blocked lane incidents are cleared within 90 minutes.
    • On average, it took one hour to get traffic moving by opening at least one lane, establishing a detour route, or providing another solution that reduced delay caused by incidents.

Litter and graffiti issues are increasing at rates greater than we can keep up with
Litter and graffiti happen in all parts of the state and ODOT, working with local governments, addresses those issues to the best of our ability.
  • In 2023, Senate bill 5701 gave ODOT $20 million in general fund dollars for litter removal, graffiti cleanup, camp cleanup and access prevention in the Portland metro area for use through June 2025.
  • In addition, we are partnering with local business leaders to pilot a Sponsor-a-Highway program that is currently removing graffiti and litter on the i-405 corridor in Portland. 

ODOT spent $22 million to clean and restore 
highway property during the 2021-23 budget cycle

Weather extremes caused by climate change have resulted in more frequent and severe emergency events 

03_Emergency Events.png
  • On average, we spend an additional $18 million every 5 years on wildfires, flooding, and other extreme weather events. These large expenses come with transportation impacts like closures and delays. For example:
    • Between 2020 and 2023, 56 wildfire events and 212 rockfalls caused over 4,300 hours of travel delays.
  • With existing resources we will be challenged to keep up with more frequent and severe weather events, which will contribute to an increase in travel delays.
2024 Durkee Fire along I-84

  • Since 2020, we’ve had 46 emergency events. Each event cost an estimated $8.2 million.  
    • Few of our emergency events qualify for federal reimbursement, meaning the cost burden is placed on the state.

The condition of ODOT roads and systems are declining

At current funding levels, state highway pavement, bridges, culverts, road signs and traffic signals are deteriorating at a faster rate than we can repair and replace them.




  • Most of the culverts we manage are near or past their 50-year design life. 
  • Culverts are key to keeping water from damaging our roads; they are especially important as climate change makes storms more intense in the coming decades.

  • Declining pavement conditions means more potholes and ruts on our roads. Potholes and ruts can damage vehicles and make travel less safe for all road users.

04_Projected 10 Year Conditions_Pavement.png


  • We manage over 18,000 miles of pavement, 88% of those miles are currently rated as  'fair' or better condition.
  • Pavement conditions began to decline in 2018.





05_Projected 10 Year Conditions_Bridges.png



  • We don't have enough funding to keep up with maintenance on all our bridges, so to balance that shortfall with public safety, we restrict heavy vehicles like semi trucks from using the bridges in worst shape. 
  • About 415 of our 2,771 bridges have restrictions for heavy vehicles over certain weights.
  • Weight restrictions negatively impact local communities and businesses. Heavy trucks carrying goods must take long, costly detours, and heavy emergency vehicles can't get where they need to go as efficiently.

2024-2028 Strategic Actions

Annual - Continue to prepare for a Cascadia Subduction Zone earthquake by making bridges and other structures seismically resilient, up to and including the construction of new structures such as the Interstate Bridge.

2025 - Complete a review of engineering guidance and standards focusing on increasing resiliency related to climate change and extreme events.

2026 - Identify resilience priorities based on risks and strategies identified in the Climate Adaptation and Resilience Roadmap, and other priority designations and plans to help the transportation system remain open and operational.

2026 - Update highway designations as part of the Oregon Highway Plan, to ensure investments are prioritized on critical routes that consider current and future condition needs to make the best use of constrained funding.

2024 Efforts Underway

Strategic Action Plan
 
  • Developing Timber Bridge Replacement Program to replace an aging population of bridges.
  • Prioritizing bridge investments that support siemic resilience while addressing other immediate bridge needs. 
  • Updating design manuals with climate risk considerations.
  • Summarizing classification and designation issues to address in the Oregon Highway Plan update. 
Other Ongoing Efforts
 
  • Information coming soon.


2024-2028 Strategic Action Plan Outcome Area


Preserve Transportation Assets:
We will protect initial investments by working to maintain transportation assets long term, keeping facilities open and operational as much as possible.

Measuring Our Success: 
Percent of bridges, pavement, culverts and signals rated as good.




Our progress this quarter:
  • Strategic Action Plan milestones created.
