Noden Causeway Deck
and Railing Replacement
Toronto Zenith was contracted to rehabilitate the Noden Causeway, a high-traffic transportation route that consists of a major section of the TransCanada Highway 11. The Noden Causeway links the communities of Thunder Bay and Fort Frances in Northern Ontario.
Objectives
- Provide high-strength low-permeability concrete in a remote area of Northern Ontario
- Achieve a tightly controlled concrete overlay surface tolerance for pre-cast panels
- Place pre-cast deck panels to a tight-placing tolerance
Key Aspects
- Worked within a narrow work zone to maintain one lane of traffic
- Worked over water and provided pilot boats to safely move boat traffic under the bridge during construction
- Rehabilitated the structure of the Noden Causeway: 614 metres long high-level structure & east and west low level structures
- Divided construction into four stages on Rainy Lake. Each stage encompassed: traffic control, removal of existing bridge surface and railing and scarifying existing concrete deck, removal of existing barrier wall, deck edge, installation of precast prestressed concrete deck panels using epoxy adhesive, construction of deck overlay, sealing concrete surfaces, installation of three beam railings and completion of transition sections at the deck ends
