Flashing Yellow Left-Turn Arrows Arrive in Southlake

flashing-yellow-arrowUPDATE 6/25/2014:  TxDOT installation of flashing yellow arrow (FYA) traffic signals on Southlake Boulevard (FM 1709) will begin this week, possibly as early as Tuesday, June 17, 2014.

The installation of the flashing yellow arrow signals will begin on the east side of Southlake Blvd and move westward towards Keller.  TxDOT contractors will be upgrading two to three intersections along Southlake Boulevard per day until the project is complete.

Commuters should expect slow moving traffic on Southlake Boulevard.  Installation of these new traffic lights is expected to last two weeks.

Once the traffic signals are operational, there are some important changes to be aware of:

  • During daytime hours, or “peak traffic times,” traffic signals along Southlake Blvd will be protected left turn signals that have the capability of changing into Flashing Yellow Arrow (FYA) left-turn signals.
  • At night, during the “off-peak” hours, most traffic signals will have the flashing yellow turn signals.

There is one exception:

  • The Davis Blvd/ Southlake Blvd (FM 1709) intersection will remain a protected left AT ALL TIMES due to high traffic volumes and the need to maintain motorist safety.

The installation of the new flashing yellow left-turn arrows traffic signals will improve safety and mobility along Southlake Boulevard (FM 1709).  In fact, a Federal Highway Administration study demonstrated that flashing yellow left-turn arrow traffic signals help prevent crashes, move more traffic through intersections, and provide additional traffic management flexibility.
