Rge Rd 250A (Nelson Road) to south of Hwy 37 – bridge replacement

Project Highlights

The County manages about 144 bridge structures, of these 91 are bridge sized culverts, 39 are standard bridges, and 14 are classified as major bridges. The average age of County’s bridges and bridge sized culverts is around 50 years old.
​
To ensure the safety of the travelling public and to provide continuous access to residents and landowners, this bridge has reached the end of its services life and is scheduled for replacement.​

​Bridge File (BF) 85336 was identified as a priority crossing due to its age and condition. Rehabilitation and replacement alternatives were reviewed; however, rehabilitation at the site is not practical due to the age, condition and capacity of the existing crossing. The crossing consists of a corrugated steel culvert that is over 70 years old and is well past the expected service life (45 years) for a steel culvert structure. The culvert is in poor condition and there is minimal cover at the crossing. Rehabilitation alternatives (lining or strutting) would make the crossing severely undersized and / or further exacerbate drift and beaver issues at the site.​

​This is structure classified as a bridge culvert, consisting of a corrugated steel culvert constructed in 1950. Replacement to this bridge has been identified and will be scheduled in 2022.​

​Recommended replacement includes removing existing structure and replacing it with a 1.8m diameter CSP culvert, capable of accommodating the design flows and meets fish passage requirements. ​
