Vista Ridge Tunnel westbound lane closures are needed for crews to install new energy-efficient LED lights

 

July 23, 2020

PORTLAND – Nighttime lane closures will switch to the westbound side of the Vista Ridge Tunnel starting on Monday night, July 27 as crews install new LED light fixtures that save money, save energy and reduce carbon emissions.

The closures will continue four nights a week from 9 p.m. to 6 a.m., Monday through Thursday nights, through Friday morning Aug. 7.

At least one lane will be open at all times during the work.

Eastbound lane closures began July 13 and will wrap up Friday morning July 24. Beginning Monday night July 27 and ending Friday morning, August 7, two westbound lanes will be closed at a time, Monday through Thursday nights, 9 p.m. to 6 a.m.

  • Beginning July 27, the left and center lanes will close with the ramp from northbound Interstate 405 to westbound U.S. 26 closed at the same time.
  • Beginning August 3, the center and right lanes will close with the ramp from southbound I-405 to westbound U.S. 26 closed during the same hours.
  • The on-ramp from Southwest Clay Street to westbound U.S. 26 will be closed at all times during the work on the westbound lanes. Clay Street on-ramp traffic will detour using either northbound or southbound Interstate 405 depending on which ramp is open that night.
  • More details about ramp detours are available on the project website.

The work is part of an ODOT pilot project converting more than 8,000 high-pressure sodium streetlights in the Portland area to light-emitting diode (LED) fixtures. The change should reduce ODOT’s energy bill for street lighting in the Portland area by half, saving taxpayers $700,000 to $800,000 a year, and lower carbon emissions because of the reduced energy use.

With ODOT maintenance crews spending less time replacing high-pressure sodium lights, they will be able to spend more time on other projects.

Most high-pressure sodium lights in the Portland area today require maintenance every two to four years but the new LED fixtures need replacing every 15 to 20 years. The longer lifecycle for each LED fixture also means less disruption to traffic created when maintenance workers replace lights.

The conversion to LED fixtures will reduce carbon emissions by an estimated 3,500 tons a year in the Portland area based on lower energy usage.

The work will take place on Portland area roads maintained by ODOT — including interstates, U.S. highways and state highways — in Clackamas, Hood River and Multnomah counties and eastern Washington County. New fixtures are also planned for both the Glenn Jackson and Interstate bridges. The project will continue periodically through the summer of 2021.

Depending on the results of the effort in the Portland area, additional LED conversions may take place in other areas around the state.
