Traffic lights tweaked on Minnesota Avenue

City crews are fine-tuning and upgrading traffic signals this week along Minnesota Avenue in hopes of improving traffic flow for drivers. Here's what's changing:

At the 10th and 11th street intersections, drivers turning left off Minnesota will begin to see flashing yellow arrows instead of red no-turn signals during certain off-peak hours. The changes mean drivers won't have to wait for a green arrow before turning west onto 10th or east on 11th. The flashing yellow arrows will appear during slower traffic times in the afternoon and late evening.

At the 26th and 41st street intersections, traffic signals are getting "visual improvements." The city's principal traffic engineer Heath Hoftiezer said he gets weekly complaints from people who say they are confused by the signals because they can be difficult to see.

At the 69th Street intersection, crews are adding a left-turn arrow, which the intersection hasn't had but now requires, Hoftiezer said.

Crosswalk signals at 10th Street were not properly synced with the new traffic signal programming, a glitch that Hoftiezer said will be fixed by Thursday evening. He said the changes shouldn't affect pedestrian safety. People walking across 10th Street will get a head start, with flashing yellow turn arrows appearing after a small delay.
