About the project

As part of the Downtown Guelph Project, and in advance of replacing underground infrastructure and rebuilding the roads in the area, the City will be completing a geotechnical investigation throughout the downtown core. This work will help inform upgrades required of our critical infrastructure necessary to provide quality service and support the vitality of our downtown core.

Activities on-site will include drilling of geotechnical boreholes to obtain underground core samples and the installation of groundwater monitoring wells.

Lane reductions

The geotechnical investigations will require partial lane closures of each road, with single lane closures taking place alternatively. Each street will remain open for traffic in both directions at all times. For two-lane streets, traffic will be required to yield to oncoming traffic. All intersections within the investigation area will remain open.

Business access and parking

All businesses in the investigation area will remain open and accessible throughout construction.

Every effort will be made to maintain access to driveways in the construction area during working hours (7 a.m.–7 p.m.). Construction activities and equipment movement may temporarily impact access to private property.

Pedestrian Access

Portions of the sidewalk along each street will need to be closed temporarily throughout the investigations. One sidewalk, on either side of the road, will always remain open for pedestrians to move through the area.

Guelph Transit

Guelph Transit routes may experience some delays during investigations. All transit stops and routes will be maintained. Visit or follow them on Facebook or Twitter for information.

The City appreciates your patience, understanding and co-operation during this important construction project. Project details and any updates will be posted on
