New Left Turn Arrow Traffic Lights Before Upgrade | Mack & Vernier

This video provides a comprehensive look at a traffic light corridor undergoing a major transformation in Grosse Pointe Woods, Michigan. Our main focus is the "Before Upgrade" state of the intersection at Mack Avenue and Vernier Road, showcasing its classic 12-inch incandescent Durasig traffic light system on a traditional wire span. However, the upgrade process is already underway, with new mast arms and black pedestrian poles already installed on-site and the old pole-mounted left-turn arrows now covered with bags due to construction.

Further down the road, we see the future of this corridor: two brand new traffic light installations—one at Sunningdale Park & Vernier Road and another at a nearby crossover—which have never had signals before. These new Durasig style LED systems are already installed on black mast arms but are currently operating in flash mode as they await full activation.

📍 Locations Featured:
Before Upgrade: Mack Ave & Vernier Rd, Grosse Pointe Woods, MI 48236
New Flashing Signals: Sunningdale Park & Vernier Rd, and a nearby Vernier Rd Crossover

This video documents the contrast between old and new traffic signal technology. The Mack & Vernier intersection features a classic incandescent traffic light setup, with two 12-inch Durasig 2-way clusters and 16 incandescent pedestrian heads. The most interesting part is seeing the new mast arm infrastructure already in place, signaling the imminent end for this vintage system. The brand new, flashing LED signals at Sunningdale Park and the crossover—complete with a "No Turn on Red" sign and a dedicated left-turn arrow—offer a clear preview of the modernization sweeping this entire corridor.

💬 Why is a traffic light flashing when it's brand new? It's typically a sign that the system is powered on but not yet fully programmed or commissioned for normal operation.
