Residents of Mississippi Mills can expect road improvements and construction activity this summer as Lanark County moves forward with an $11.8 million capital construction program. Running from May through November 2026, the work includes major upgrades to local intersections, bridge repairs, and broader road maintenance throughout the area.
One of the most significant local projects is a joint effort between the county and Mississippi Mills to improve traffic flow in Almonte. Starting in late May, Orin Contractors Corporation will construct dedicated left-turn lanes at the intersection of Christian Street and Almonte Street. This $554,428 project will also include new traffic signals and is expected to continue through October.
In Pakenham, the historic 5-Arches Bridge will see further preservation work. Bonnechere Excavating Inc. is handling the second phase of rehabilitation on the 1901 stone structure. This $1.6 million project, which involves replacing deteriorated stone and improving the deck and lighting, is expected to finish by mid-November.
Elsewhere in the region, Thomas Cavanagh Construction Ltd. is performing 3.4 km of rehabilitation work on County Road 511. That project, which began in mid-April, is expected to be complete by June 12. Across the county, public works crews are also focused on pavement preservation, shouldering, and road rehabilitation to maintain more than 560 km of infrastructure.
The county advises that motorists should expect periodic single-lane traffic in areas where construction is taking place. Public Works Director Sean Derouin asks drivers to obey all posted signage and follow the directions of traffic control personnel to ensure the safety of both workers and the public.
