The northbound structure of Burlington Bay Skyway in Hamilton, Ontario recently underwent major rehabilitation. This included a component for the recoating of the structural steel in the 150 m-long overhead main span arch. The primary operational constraint was that traffic lanes stay open throughout construction. The additional gravity loads and wind loads from the scaffolding and environmental enclosures posed serious structural overload concerns. Extensive computer analysis and scenario testing enabled the development of a staging arrangement, structural strengthening scheme, high wind closure protocol integrated with rapid lane closure gates, and an overheight vehicle detection advanced warning system. This rehabilitation of the bridge commenced in Spring 2014 and was completed on time in Fall 2016 with no significant traffic delays or disruptions. Structural integrity was successfully maintained throughout construction. |
