City of Sammamish - COVID-19 (Coronavirus) Information & Resources
OVERVIEW
Flashing Yellow Arrow (FYA) turn signals are widely used to improve signal operations and traffic safety. In 2017, the City conducted a FYA feasibility study for all of the city's signalized intersections. The analysis identified those intersections that met certain physical configuration and safety criteria making it feasible to install FYA left turn signals.
The City installed FYA at 13 intersections in 2017-18 and decided to install additional FYA at up to 10 intersections in 2019. Project is currently advertised. The table below shows locations where FYA will be installed with this project:
