 Project background
We are improving our RealTime system to make roads safer and help Oregonians get where they are going more efficiently by providing real-time traffic information to drivers.
The work includes installing RealTime Variable Advisory Speed (VAS) signs along a busy stretch of Interstate 5 south of downtown Portland from the Ross Island Bridge to Terwilliger Boulevard.
Work will finish in late 2025.
