Motorists across Ontario are being urged to plan their trips wisely, as several major highways will undergo significant roadwork or remain closed due to adverse weather conditions on March 6, 2025. According to reports from Ontario 511, it’s imperative for drivers to stay informed about the planned closures to avoid inconveniences and potential fines.
Notably, Highway 403 is set to accommodate roadwork starting from March 4, with closures affecting both directions. Specifically, two right lanes will be closed on the eastbound section between Queen Elizabeth Way, Oakville, and Highway 5 / Dundas Street, Mississauga, from March 4 at 10 p.m. until March 6 at 5 a.m. Similarly, one alternating lane is expected to be closed on Highway 403 eastbound between Highway 5 and Burnhamthorpe Road, Mississauga, from March 3 at 10 p.m. until March 7 at 5 a.m.
Additional closures along Highway 403 include the right off-ramp to Queen Elizabeth Way bound for Toronto, which will also see one lane shut down from March 11 at 10 p.m. to March 12 at 5 a.m. Meanwhile, one alternating lane will be closed on the westbound route of Highway 403 between Highway 5 / Dundas Street for the same timeframe as the eastbound closure.
Further north, Durham Region is similarly affected by multiple lane closures. Highway 12 northbound between Talbot River Br, Ramara, and Atherley Rd, Orillia, will see one alternating lane closed from March 2 at 8 p.m. until March 8 at 7 a.m., with another alternating lane closure scheduled from March 9 at 8 p.m. until March 15 at 7 a.m. Concurrently, both lanes of Highway 401, eastbound and westbound, between Simcoe Street and Harmony Road, Oshawa, will see left lane closures from March 6 at 10 p.m. until March 7 at 5 a.m.
It's also worth noting weather-related impacts on travel. Reports indicate Highway 11 from Calstock to Iroquois Falls is still closed, as are highways 655 leading to Timmins and 144 routing to Sudbury. This situation raises concerns over travel safety, as police have highlighted steep consequences for those attempting to use closed roads. Specifically, the fine for driving on these closed highways amounts to $110 and may result in the loss of three demerit points. "Travelling on a closed road is illegal and your insurance may not cover you if you get involved in an accident," warns Ontario 511.
Weather conditions have also compelled the totalité of Highway 129 between the S JCT Highway 101, Chapleau, and Highway 17-River St., Thessalon, to close entirely since March 5. Motorists should anticipate delays as they encounter traffic issues on these routes. Current travel time on impacted routes, such as Thessalon-Timmins, is approximately two hours and thirty-four minutes, compared to the standard travel time of two hours and fifty-four minutes, indicating substantial slowdown. The Sault-Sudbury route sees similar delays, with travel times reaching over three hours.
With roadwork and inclement weather generating significant traffic disruptions, it remains increasingly important for drivers to be cognizant of road conditions prior to hitting the road. Consultation of real-time updates via Ontario 511 can assist travelers significantly, helping them navigate around closures and adjust their itineraries accordingly. Ignoring road signage warning of closures not only leads to fines but can have serious safety ramifications.
For those who find themselves on the road when yellow caution boards indicate closures, the importance of adhering to law enforcement protocols and exercised caution cannot be overstated. Emergencies and accidents can arise swiftly, underscoring the importance of thorough preparation and diligence before embarking on any roadway adventures across Ontario.
