NEWPORT BEACH...Last Wednesday, August 19, a major traffic collision on MacArthur Boulevard south of Bonita Canyon Drive required the closure of all southbound lanes for several hours.

As motorists were diverted onto surrounding streets, the City’s Public Works Traffic Engineering Division worked behind the scenes to help manage traffic and reduce congestion.

Using real-time intersection cameras and remote access to the City’s traffic signal system, Traffic Engineering staff monitored traffic conditions and adjusted signal timing along MacArthur Boulevard, Bonita Canyon Drive and nearby intersections.

The adjustments provided additional green-light time along alternate routes, helping improve traffic flow and minimize delays until the roadway reopened.
