The traffic signal at 5th Street and Front Avenue will be powered down on Tuesday, October 27, 2026, and replaced with an all-way stop for a trial period of several months. [City of Bismarck] [Bismarck Source]
The signal was installed in 1978 and has been in service for 48 years, well beyond the typical 30 to 40 year lifespan of traffic signals. [City of Bismarck] [Bismarck Source]
The change precedes a 2027 road construction project on Front Avenue and 5th Street that will include permanent modifications to the intersection. [City of Bismarck] [Bismarck Source]
Current traffic volumes at the intersection do not meet federal criteria required to install a new traffic signal. [City of Bismarck] [Bismarck Source]
A study comparing operations found that an all-way stop would produce shorter vehicle lines and shorter wait times than the current signal. [City of Bismarck] [Bismarck Source]
During the trial, the city will review any crashes and coordinate with BNSF Railroad to monitor operations, especially after trains pass the railroad crossing north of the intersection. [City of Bismarck] [Bismarck Source]
