Sunny Creek Crossing





Tatham provided engineering services for a private crossing over Sunny Creek, an outlet between Three Mile Lake and Kahshe Lake, located within the Town of Gravenhurst boundary area. The modular, single-lane bridge is founded on cast-in-place concrete footings anchored to exposed bedrock.

In order to provide a cost-effective solution working with our client, we conducted a preliminary site visit to review conditions and provided cost comparisons for several options. With a desired solution in mind, the preliminary and detailed design of the crossing was completed. Tatham provided support during construction and guidance for maintenance to sustain performance and provide a long service life.
