Notice of Activation of Reduced Load Period
It is an offence, under section 122 of The Highway Traffic Act, to transport loads in excess of five (5) tonnes per axle upon roads where reduced loads are in effect.
Take notice that in accordance with The Corporation of the County of Lanark By-Law #99-07, reduced load restrictions will be in force on designated County Roads effective Monday, March 2, 2026.
This restriction will apply only on those County Roads that are posted with the appropriate signs.
A map of all County Roads and the list of County Road exceptions where reduced load periods are not in effect can be viewed here: Reduced Load Restrictions List & Map 2026
The reduced load period is necessary for the protection of certain County Roads that are susceptible to damage during the spring thaw. The restriction will be removed when the likelihood of road damage has diminished.

Andrewsville Bridge
The Counties of Lanark and Leeds Grenville have retained Jewell Engineering to prepare a Municipal Class Environmental Assessment (EA) report to evaluate alternatives to address the deteriorating condition of the Andrewsville Bridge over the Rideau River, located in the hamlet of Andrewsville about 5 km north of the Village of Merrickville.
Andrewsville bridge is designated as a boundary bridge, therefore it is jointly maintained by the County of Lanark and the United Counties of Leeds and Grenville. For further documentation about the status of this project, please contact Lanark County Public Works.
Class Environmental Assessment for the Andrewsville Bridge
The Counties of Lanark and Leeds and Grenville are undertaking a Municipal Class Environmental Assessment for the review of alternatives for the Andrewsville Bridge, located in the hamlet of Andrewsville, over the Rideau River, approximately 5km north of the Village of Merrickville. The options review is a priority for the Counties due to the bridge’s age and condition, posted weight restriction and seasonal operation, and its potential cultural and heritage value. As part of the Environmental Assessment process, options for bridge reconstruction including the possible permanent decommissioning, will be reviewed to determine the preferred solution.
The project is being initiated in accordance with the latest edition of the Municipal Class Environmental Assessment Manual issued by the Municipal Engineers Association. The Municipal Class Environmental Assessment process applies to municipal infrastructure projects including road and bridge works. This project is proceeding as a Schedule ‘B’ undertaking in accordance with the Municipal Class Environmental Assessment Manual.
Public and agency consultation is an important component of the Environmental Assessment process. In addition to this notice, a Public Consultation Centre will be planned where the public will be invited to review options, ask questions, and provide comments. The date and time of the PCC will be provided in the near future.
Subject to comments received and the receipt of necessary approvals, the Counties of Lanark and Leeds and Grenville intend to proceed with the planning, design, and implementation of the preferred alternative.

Constructed in the early 1900’s, the Bridge is composed of two simply supported structures: a 38-metre span steel through- truss with timber deck (west approach); and a 10-metre span timber deck on a rolled steel girders (east approach).
Andrewsville Bridge has had a 5-tonne load limit imposed since 1952, which is the same load limit of the adjacent swing bridge. Average daily traffic is less than 200 cars per day.
Structural inspections have identified that the bridge has outlived its normal service life noting the original steel superstructure continues to deteriorate at an ever-increasing rate. The biggest concern is the stability of the 70 metre drystone retaining wall on the south approach that is at risk of collapse.
The timber deck of the main structure was replaced in 2008 along with minor structural repairs.
In the 2012, the bridge was struck and damaged by a transport trailer and was closed indefinitely due to the damage. As a result, discussion was prompted for the consideration of permanent closure as the best long-term solution. Residents protested this and formed the group “The Friends of Andrewsville Bridge”, initiating the campaign “Save the Andrewsville Bridge” where they organized petitions and persuaded Township and County Councillors to preserve the bridge.
Repairs as a result of the truck collision were completed and the bridge was opened to traffic in March of 2013. Height restricting barriers were also installed at this time to deter large vehicles from attempting to cross.
The west end approach steel stringers were replaced in 2016 and the east end stringers in 2018.
Council passed a by-law in 2018 approving recommendation to close the bridge to traffic on an annual basis from December 1st to March 31st to prolong the lifespan of the bridge by eliminating further corrosion as a result of de-icing materials being tracked across the bridge.
The County has completed enhanced inspections on the bridge on a yearly basis and will continue to monitor its condition throughout the Municipal Class EA process.

K & P Trail Acquisition
The County of Lanark is excited to be working towards the acquisition of the K & P trail in Lanark Highlands. The K & P was decommissioned as a rail line in the 1960s and since then has been accessed by the public as a trail and special interest transportation link. Most recently the trail has been owned and managed by Mississippi Valley Conservation Authority (MVCA). In December, 2025 the MVCA entered into agreements with Frontenac, Lanark and Renfrew Counties to transfer the trail sections in each county to the respective counties.
The County has recently sent a communication to landowners related to this acquisition.
Frequently Asked Questions
If the County chooses not to proceed with the purchase of the trail, Lanark County Council will explore options with MVCA to continue its mandate to maintain the availability of the trails for public recreational use.
If you are an adjacent landowner and you have not been contacted directly by the County, please contact:

If you have more questions related to the Lanark Highlands plowing, please contact Kathryn Maton, Public Works Manager, at Lanark Highlands Township.
Detailed information related to timing and location of the public information sessions will be provided in March. Please continue to monitor this website page and The County of Lanark Facebook page for more information regarding the public information sessions.
We welcome feedback from the public on this item at any time. Please contact Cindy Deachman for further information.
The trail use rules will also be discussed as part of the public information sessions referenced above and we welcome feedback from landowners, stakeholders and trail users prior to the formal adoption of the rules.
