Structure Condition Structure is 80 years old Various elements have deteriorated
Cracking, spalling, disintegration, exposed rebar
Due to its deteriorating condition, it was posted with a 12 tonne load limit in 2017
2020 Bridge Condition Index (BCI) rating was calculated to be 25.4 (out of 100), one of the lowest in the Municipality
Lifecycle cost analysis concluded the structure is beyond economic rehabilitation
Options considered: permanently close the structure or replace Municipality decided to replace the structure
