Coquitlam signal work will darken Lougheed and Dewdney lights

Coquitlam drivers using **Lougheed Highway and Dewdney Trunk Road** should expect traffic control at that intersection overnight Thursday. The city says traffic signal equipment upgrades are scheduled for **July 23**, weather permitting. The work is planned from **10 p.m. to 5 a.m.** During that window, Coquitlam says the traffic signal will be dark and the intersection will be managed by traffic control personnel. ## What drivers should expect The city notice says drivers should plan an alternate route to avoid delays or plan extra time when using the intersection. The warning is narrow, but useful because the traffic signal itself is expected to be dark during the work window. Coquitlam says drivers should travel with caution through construction zones, watch for work crews and equipment, obey traffic personnel and signs, and follow construction speed limits. Readers tracking other active road work can compare this notice with the city's broader [Coquitlam road work at Parkway and Panorama](/transit/coquitlam-parkway-panorama-road-work), which is also affecting local trip planning this summer. ## Where to check before leaving The most useful source is the city notice because it names the work window, intersection, and traffic-control setup. Coquitlam's Traffic Hotspots page is the broader city page for summer road work and traffic bulletins, including the city's reminder that summer work can overlap with projects by utilities and regional agencies. DriveBC also lists a Lougheed Highway camera at Dewdney Trunk Road. That can help drivers check visible conditions before using the route, but the city notice is the source for the scheduled signal work. Before leaving Thursday night, check the official notice for the **10 p.m. to 5 a.m.** window and treat the intersection as a traffic-control zone if the signal is dark. ## Sources - [City of Coquitlam traffic signal maintenance notice](https://www.coquitlam.ca/m/newsflash/Home/Detail/2007) - [City of Coquitlam Traffic Hotspots](https://www.coquitlam.ca/198/Traffic-Hotspots) - [DriveBC Lougheed at Dewdney Trunk Road camera](https://www.drivebc.ca/cameras/366)
