Archived location and details of all recorded emergency road and/or lane closures or other impacts on roadways in and around the City of Ottawa. In 2018, the earliest archived event logs are from March 2018. <br /><br /> <strong>Accuracy</strong>: Information is based on incidents that were recorded by staff in the Traffic Operations Center. It is not comprehensive of all road closures and traffic incidents. <br /><br /> 1) The entered and ended times indicate the time an event was displayed and removed from the Interactive Traffic Map. It is generally an accurate representation of the actual duration of the event, but actual event duration may vary from these times. <br /><br /> 2) Some events may have impacts that change over time. The event snapshots in the reports may not capture changes that occur over the duration of the event. <br /><br /> 3) For a major event with multiple impacts, the street1/street2/street3 fields may contain the name of the event (e.g. Canada Day Downtown) or a description of the area (e.g. Multiple closures in downtown core).
