5-Arches Bridge rehabilitation begins May 11
Lanark County will begin construction on the second phase of the 5-Arches Bridge Rehabilitation Project on May 11, 2026, which will involve a full road closure for the duration of the project.
The County has awarded the contract to BEI Bonnechere Excavating Inc. The project includes masonry and stone repairs, road approach improvements and new lighting installation beneath and on the bridge to enhance safety and preserve the structure for long-term use.
“These works form the next phase of the County’s ongoing investment in maintaining this important historic crossing in the community,” said Public Works Director Sean Derouin.
To allow the work to be completed safely and efficiently, the full road closure will be in effect beginning Monday, May 11 at the bridge location for the duration of the project. No through traffic will be permitted, and signed detour routes will be posted in advance and maintained throughout construction.
The County appreciates the public’s patience and cooperation while this essential rehabilitation work is completed. Further updates will be provided as construction progresses. For more information, please visit the County website at: www.lanarkcounty.ca/5arches
