The City will be terminating programmed flash – setting traffic signals to flash during early morning hours – at several intersections citywide.

Programmed flash will be eliminated at the following intersections beginning Monday, Jan. 18:

  • Addison at Francis
  • Addison at Wellesley
  • Alberta at Wellesley
  • Ash at Broadway
  • Belt at Wellesley
  • Bernard at 29th
  • Broadway at Jefferson
  • Buckeye at Post
  • Crestline at Euclid and North  Foothills

  • Hawthorne at Nevada
  • Holland at Nevada
  • Illinois at Perry
  • Jay at Nevada
  • Lincoln at Nevada
  • Lyons at Nevada
  • Magnesium at Nevada
  • Market at Queen
  • Mission at Napa
  • MLK at Pine

  • Ray at 17th
  • Ray at 29th
  • Regal at 37th

  • SE Blvd at 29th

Vehicle detection systems were recently installed at each intersection, so programmed flash is no longer needed to facilitate traffic flows. Vehicle detection allows the signals to respond promptly to vehicle demand. The system will allow for more efficient service during low volumes times when programmed flash was previously used (1 a.m. to 5 a.m. weekdays and 2 a.m. to 5 a.m. on weekends).

Eliminating programmed flash also provides for 24/7 operation of pedestrian signals at those intersections. Pedestrian signals do not work during programmed flash.
