Knights Bridge Road/Arndt Road intersection safety improvements


Planning phase

Updated: Nov. 15, 2023

Reducing rear-end crashes by improving visibility of intersection

Most crashes at this intersection are rear-end collisions. Includes installing a radar detection system to detect vehicles as they approach the Knights Bridge Road/Arndt Road intersection. The detection prevents the signal from changing to another direction prematurely and placing drivers in a dilemma of deciding to go through the intersection or not, causing longer wait times. Also adding signal ahead signs and pavement markings to alert drivers of changing conditions. 


To provide a safer roadway for all users by increasing visibility of intersection.
