Drivers in Eugene should expect delays on several major streets on Thursday and Friday, Oct. 16-17, as crews upgrade traffic signals and install new equipment, the city announced Wednesday.

Signals will flash red along the affected roadways on a rolling basis as work is done at the following intersections, said city spokesperson Marion Suitor Barnes.

  • Sixth Avenue, from Charnelton Street to Garfield Street (1.3 miles)
  • Seventh Avenue, from Charnelton Street to Garfield Street (1.3 miles)
  • West 11th Avenue, from Garfield Street to Randy Papé Beltline (2.5 miles)
  • West 13th Avenue, from Charnelton Street to Alder Street (0.8 miles)
  • River Road from Northwest Expressway to River Loop 1 (3.7 miles)
  • Various intersections on Highway 99

A flashing red light should be treated as an all-way stop sign, and will likely result in traffic slowdowns. Drivers should consider alternate routes or leave early to allow for extra travel time, city officials said.

The city’s annual budget for traffic signal maintenance and operations is about $1.3 million, according to a city fact sheet from February. Each intersection with signals has a computer controlling its operation, according to the city. The timing of signals and types of signals vary by intersection.
