Municipality of Middlesex Centre, Bridge/Culvert Replacements

​SBM completed the design and construction administration for the replacement of two bridge-culverts for the Municipality of Middlesex Centre. Using a hybrid Corrugated Steel and concrete footing with wall design, we were able to achieve a 100-year expected service life with a low-maintenance, cost-effective, flexible structure. The open-bottom CSP box culvert allows for any frost movement to be absorbed without causing detrimental damage to the structure, while being less expensive and easier to install than concrete.
