Info-Work: Temporary Road Closure: Washago at Couchiching Lock 42

Trent-Severn Waterway National Historic Site

Peterborough, Ontario, June 13, 2019 – Parks Canada advises that a temporary road closure will be in place at the Couchiching Lock 42 fixed bridge on Canal Road along the Trent-Severn Waterway in Washago. The closure will be in effect from Monday, June 17 to Thursday, June 27, between 7:00 a.m. and 9:00 p.m. The road will be open to vehicle traffic on the weekends. The bridge at this location has been identified for future replacement. The closure will enable contractors to set up a drill rig on the bridge and gather geotechnical information for project planning.

Geotechnical Work at Couchiching Lock 42

Geotechnical work provides important information about the composition and integrity of soils, bedrock and other materials, like concrete, which is used to plan the design of projects and structures. There are many ways of obtaining this information: test pits dug with an excavator, boreholes in earth or rock using a drill rig and auger, concrete core sampling with a smaller drill rig or portable system, or seismic sounding line. At Couchiching Lock 42, boreholes will be drilled and concrete core samples taken within the lock, along the lock walls, along the upstream and downstream approach walls, and on the fixed bridge.

Public Safety is a priority for Parks Canada. Every effort is made to minimize the visitor impact of these infrastructure projects, however at times access to certain areas must be limited or restricted to ensure the safety of visitors and staff. During this important work, here is what visitors can expect at Lock 42:
* Please obey signage and the instructions of lock staff.

From June 13 – June 27:

  • Overnight boat mooring at this site not recommended;
  • Limited use of approach walls for boat navigation;
  • Construction noise between the hours of 7:00 am and 9:00 pm;
  • Large machinery at the lock station; and,
  • Some areas of the lock station will be fenced and closed to visitors.

The repair of infrastructure on the Trent-Severn Waterway is part of Parks Canada’s unprecedented $3 billion investment over five years to support infrastructure work to heritage, visitor, waterway, and highway assets located within national historic sites, national parks, and national marine conservation areas across Canada.
