Many of the existing traffic signals in the County have exceeded their intended service life. This ongoing initiative reconstructs outdated traffic signals to meet current Federal and County standards and specifications. Each Signal upgrade project implements the latest technologies such as accessible pedestrian signals, CCTV for monitoring, video detection, and better intersection lighting to improve safety, efficiency, and accessibility for all road users.
Learn more about our traffic signals and technology here.
Transportation Engineers consider a variety of factors when prioritizing signal upgrade locations, including the type of signal, age of the infrastructure, and the type of roadway facilities impacted. Each signal upgrade requires a design phase and a construction phase.
This project is funded by a variety of sources including County funds, Northern Virginia Transportation Authority (NVTA) funds, and other sources of revenue. The project is administered locally by Arlington County staff.
