The Ontario government will begin four-laning the final 68 kilometres [1] of Highway 69 within the next year [1, 2].
This expansion aims to resolve long-standing safety concerns and reduce travel times for motorists traveling to Sudbury. The project is expected to support regional economic development by completing a critical link in the province's transportation network [2, 3].
Transportation Minister Prabmeet Sarkaria said the plan is to expand the stretch of highway located north of Key River. A primary requirement for the expansion involves relocating a section of CN Rail tracks to make room for the additional lanes [1, 2].
The project is divided into six phases [1]. According to government reports, four of those phases are expected to begin construction within the next year [1]. While some reports specify a start date in 2027 [3], others indicate work will commence by the end of 2027 [1, 2].
Despite the timeline for breaking ground, the Ministry of Transportation has not provided a set completion date for the entire project [1]. The effort focuses on the final segment of the highway south of Sudbury, which has remained a two-lane bottleneck for years [1, 2].
The province has prioritized this section to improve the flow of traffic and reduce the frequency of accidents on the corridor [2, 3]. The relocation of the rail infrastructure represents one of the most complex engineering hurdles in the final push to finish the highway upgrade [1].
“The province plans to relocate CN Rail tracks to expand the 68-km stretch north of Key River.”
The completion of Highway 69 is a long-term infrastructure goal for Northern Ontario. By addressing the rail-track bottleneck and expanding to four lanes, the province is attempting to modernize a high-traffic corridor that has historically been prone to congestion and safety risks, though the lack of a firm completion date suggests potential for further delays.
