Culvert deterioration doesn’t happen overnight, yet its effects can be substantial when it comes to roadway damage from sinkholes, road collapse and even flooding. In some cases, complete culvert replacement isn’t necessary. In fact, many counties and cities opt for culvert rehabilitation instead of replacement because it offers:
> No roadway shutdown
> No traffic re-routing
> No disruption of the pavement and roadway embankment
> Minimize drainage disruption
> Overall lower cost than removal and replacement
