Improvements Coming to I-205

Construction begins in late March!

Construction begins later this month on a project to improve the condition, traffic flow and safety on Interstate 205 between Johnson Creek Boulevard and the Glenn Jackson Bridge. The project includes:

  • Repaving approximately nine miles of I-205, freeway ramps and intersections.
  • Building auxiliary lanes in three locations.
  • Installing ODOT RealTime traveler information and advisory signs.
  • Improving the entrance to the multi-use path at Glisan Street.
  • Improving sidewalk curb ramps within the project area.

Construction mostly takes place at night to minimize traffic impacts during the day. Work will continue through 2019.

Traffic Impacts During Construction

  • Night time lane, ramp and shoulder closures in both directions on I-205.
  • Full overnight closures on I-205, follow signed detour routes.
  • Multiple overnight closures on several I-205 entrance and exit ramps.
  • Lane closures on cross-streets near on-ramps and off-ramps, with occasional flaggers at intersections.
  • TriMet buses may experience detours in some areas.

Sundays through Thursdays:

  • 8 p.m. to 5:30 a.m. (single lane closure times)
