Motorists searching for information about a Highway 417 accident today should check official traffic sources before travelling through Ottawa, as collisions, disabled vehicles, construction and emergency responses can quickly affect traffic on the Queensway.
As of Saturday afternoon, September 26, 2026, Ottawa’s official traffic-events feed did not list a new active collision on Highway 417 at the time of checking. However, several construction-related lane and ramp restrictions remain active and could cause delays for drivers travelling through the city.
Because Highway 417 traffic conditions can change within minutes, motorists should continue checking Ontario 511 and the City of Ottawa traffic map before starting their journey.
Latest Highway 417 Traffic Update
While no major active Highway 417 collision was listed in the official Ottawa traffic feed at the time this update was prepared, drivers should expect possible congestion in several areas of the highway.
Construction remains active in both directions between Kent Street and Carling Avenue/Kirkwood Avenue.
The Ministry of Transportation listing shows alternating lane closures affecting Highway 417 eastbound and westbound through 9 p.m. on September 26. Ramp closures may also occur as work continues.
Drivers travelling through central Ottawa should allow additional time and watch for changing lane configurations.
Highway 417 Moodie Drive Ramp Closures
Another significant traffic issue involves Highway 417 at Moodie Drive in Ottawa’s west end.
The westbound Highway 417 on-ramp at Moodie Drive is subject to nightly closures through September 30.
The official traffic listing shows the ramp completely closed during scheduled nighttime construction periods.
The Highway 417 westbound off-ramp at Moodie Drive is also affected by nighttime construction, with closures scheduled through October 3, 2026.
Motorists travelling between Kanata and central Ottawa should watch for posted detours.
Is Highway 417 Closed Today?
Highway 417 itself was not listed as completely closed through Ottawa at the time of this update.
However, temporary lane and ramp closures associated with construction may affect travel times.
The most notable current restrictions include:
- Alternating lanes between Kent Street and Carling Avenue/Kirkwood Avenue
- Westbound Moodie Drive on-ramp closures
- Westbound Moodie Drive off-ramp closures
- Ongoing construction near the Richmond Road/Bayshore interchange
Conditions may change if a collision or emergency occurs.
How to Check Highway 417 Accidents in Real Time
The City of Ottawa traffic map provides information about incidents, construction, special events and road restrictions throughout Ottawa.
The city’s traffic system also incorporates Ministry of Transportation information for Highway 417 and other provincial highways.
Drivers can also use Ontario 511 to check:
- Highway 417 collisions
- Lane closures
- Disabled vehicles
- Police investigations
- Road construction
- Highway cameras
- Weather-related road conditions
Traffic cameras are especially useful for checking congestion before travelling.
Highway 417 Traffic Cameras
Ottawa and the Ministry of Transportation operate multiple traffic cameras along Highway 417.
For example, an MTO camera is available on Highway 417 east of Moodie Drive, with images refreshing regularly.
Cameras are positioned at numerous locations along the Queensway, making it possible for motorists to check traffic conditions near major interchanges.
Why Highway 417 Accidents Cause Major Ottawa Delays
Highway 417 is one of Ottawa’s most important transportation corridors.
The Queensway carries large volumes of traffic through:
- Kanata
- Nepean
- Downtown Ottawa
- Vanier
- Gloucester
- Ottawa’s eastern suburbs
A collision blocking even one or two lanes can quickly create congestion extending several kilometres.
Delays can become especially severe during morning and afternoon rush hours.
Recent Highway 417 Collisions
Highway 417 has experienced several collisions and incidents in recent weeks.
On September 21, a collision on Highway 417 westbound at Richmond Road/Bayshore Drive resulted in two centre lanes being closed.
On September 20, another collision affected Highway 417 westbound near Parkdale Avenue, closing the left shoulder and two left lanes.
Other September incidents have affected Highway 417 near Woodroffe Avenue, Carling Avenue/Kirkwood Avenue, Vanier Parkway and Huntmar Drive.
These earlier collisions should not be confused with a new accident occurring today.
What to Do If You Encounter a Highway 417 Accident
If you approach a collision scene on Highway 417:
- Reduce your speed
- Avoid sudden lane changes
- Follow police and emergency-worker instructions
- Do not use the shoulder to bypass traffic
- Give emergency vehicles plenty of space
- Use an alternate route if officials recommend one
- Never stop to photograph or record a collision
Drivers should also move over when approaching emergency vehicles stopped along the highway where required by Ontario law.
Alternative Routes During Highway 417 Delays
The best alternative route depends on where the collision or closure occurs.
Possible east-west alternatives through Ottawa can include:
- Carling Avenue
- Baseline Road
- Richmond Road
- Hunt Club Road
- Innes Road
- Highway 174 for some east-end trips
However, diverting large amounts of highway traffic onto local roads can quickly create congestion.
Drivers should check live traffic information before choosing an alternate route.
Highway 417 Traffic Could Be Busier Saturday Evening
Motorists heading toward Kanata should also plan for additional traffic around the Canadian Tire Centre.
The Ottawa Senators are scheduled to play the Montreal Canadiens at 7 p.m. on Saturday, September 26, 2026, which could increase traffic approaching Kanata and the Palladium Drive area of Highway 417.
Drivers heading through Ottawa’s west end during the evening should allow extra travel time.
Who Responds to Highway 417 Accidents?
Highway 417 is a provincial highway.
Depending on the location and circumstances of an incident, emergency response may involve:
- Ontario Provincial Police
- Ottawa Fire Services
- Ottawa Paramedic Service
- Ministry of Transportation crews
- Towing and recovery services
Serious collisions may require lanes or the entire highway to remain closed while emergency crews investigate and safely clear the scene.
How Long Can a Highway 417 Closure Last?
There is no fixed reopening time following an accident.
A minor collision may be cleared relatively quickly, while a serious crash involving injuries, multiple vehicles, commercial trucks or damaged infrastructure can require a much longer closure.
Police investigations can also extend the amount of time a section of highway remains inaccessible.
Drivers should therefore treat estimated reopening times as subject to change.
