I-5 ODOT RealTime Signs (Ross Island Bridge to Terwilliger Boulevard) 

Design Phase

Region 1: Portland metro and Hood River County (Portland, Multnomah)


​​ODOT is installing RealTime Variable Advisory Speed (VAS) signs along a busy stretch of Interstate 5 through south Portland from the Ross Island Bridge to Terwilliger Bouleva​​rd. Realtime VAS signs give drivers notice to slow down before they reach a problem area — improving traffic flow and helping to reduce rear-end crashes and congestion.



Impacts

Construction Impacts

During construction, travelers can expect:

  • Nighttime lane closures on I-5.
  • Several weekends in 2025 where a lane will be closed in each direction around-the-clock on I-5.
  • Overnight full closures of I-5 in both directions for several nights in summer 2025 while the new sign bridges are set in place.

We will share more information about construction and detour routes in advance of work beginning.

Schedule

The signs will be installed in 2025. Two of the installations include building new sign bridges over the freeway.

Design: Spring 2023–Summer 2024

Construction: Fall 2024–Winter 2025

About

ODOT is improving its RealTime system to make roads safer and help Oregonians get where they're going more efficiently by providing real-time traffic information to drivers. We are installing RealTime Variable Advisory Speed (VAS) signs along a busy stretch of Interstate 5 through south Portland from the Ross Island Bridge to Terwilliger Boulevard. Realtime VAS signs give drivers notice to slow down before they reach a problem area—improving traffic flow and helping to reduce rear-end crashes and congestion.

This project will:

  • Install 12 RealTime VAS signs at two locations – three signs per direction near SW California Street (south of Exit 298) and near S Hamilton Street (south of Exit 299). These two installations include building new truss sign bridges over the freeway.
  • Upgrade the variable message sign on I-5 north near Iowa Street (south of Exit 298).

Safety Improvements

Realtime VAS signs calculate and display advisory speeds based on conditions ahead using traffic sensors, weather sensors, and cameras along the roadway.

RealTime VAS signs:

  • Improve safety and traffic flow by reducing crashes and their associated delays.
  • Help prevent rear-end crashes by warning drivers of slowdowns ahead.
  • Give drivers advance notice about speed changes ahead due to current conditions and empower them to make real-time decisions.
