Traffic Signal Upgrade Project

The City of Mount Pearl has recently commenced a traffic signalization upgrade project that will reduce congestion, enhance traffic flow and improve accessibility and safety for pedestrians. Over the next several weeks, various locations throughout the City will receive new intersection lighting and timing.

The City of Mount Pearl has a total of 26 traffic signals, including signalized intersections and pedestrian activated crosswalks. When the project is complete, upgrades will include new signal controllers, new vehicle detection, and in some cases new poles and signal displays.

Almost all locations will undergo upgrades. Associated street work will be required at the following locations to accommodate the installation of vehicle detectors and/or underground electrical conduit.

• Old Placentia Road/Nelder Drive
• Old Placentia Road/Ruth Avenue
• Old Placentia Road/Smallwood Drive
• Old Placentia Road/Dominion Entrance
• Ruth Avenue/Roosevelt Avenue
• Topsail Road/Commonwealth Avenue
• Topsail Road/Thomas Byrne Drive
• Richard Nolan Drive/Merchant Drive

Lane closures and traffic delays are to be expected throughout the traffic signalization upgrade project. The City of Mount Pearl appreciates the cooperation of motorists at this time. For regular traffic advisories, please check below.
