The Utah Department of Transportation has received your request and we will be looking into the issue. Thank you for taking the time to let us know.

Thank you for contacting UDOT. Signals along 3500 South are timed to prioritize flow along the major corridor to minimize the number of stops for the higher volume of vehicles. The occasional short movement times you're seeing are due to the signal needing to service pedestrians. The signal needs to borrow extra time from another movement to service pedestrians without interrupting the east- and westbound movement, resulting in occasional shorter north and south turn movements.
