The Highway 107/102 Southbound Overpass creates a link between Highways 107 and 102 near Rocky Lake and the Bedford Commons in Nova Scotia. Harbourside Engineering provided the preliminary and detailed structural bridge and geotechnical design services for this project, as well as erection engineering. The project was awarded the 2025 Steel Design Award for Excellence by the CISC in the category of Bridge Projects. This overpass and the improvements to Highway 107/102 help to improve transportation throughout HRM.

Harbourside Engineering provided erection engineering services for the fabrication, transportation, and erection of four steel arch bridges for Waterfront Toronto, Ontario. Two of the new bridges cross the Keating Channel to replace the previous Cherry Street North Bridge, and the other two, on Cherry Street and Commissioners Street, cross the new river valley at the mouth of the Don River. Most of the work to build and coat these structures was completed in Nova Scotia, and they were later transported by barge to Toronto.

The original Victoria Bridge, serving as the main connection between Old South and downtown London via Ridout street over the Thames River in Ontario, needed replacement. E.S. Fox Limited (ESF) was awarded the construction project and engaged Harbourside to provide erection and construction engineering services. The replacement of the bridge involved the removal of the two-span bridge and the construction of a twin-rib arch supporting structure along Ridout Street South. In 2024, the Victoria Bridge won the CISC steel design award for engineering excellence in Ontario.
