Anyone out there have any experience building bridges? Private or for the county or anything like that? I'm looking for some help for my parents, who had a catastrophic failure of their culvert system that runs under the only access into and out of their property. Guidance, experience, knowledge, looking for any help we can get for them at this point. It's on private property, and not off a county road so the city, county, state, fed, insurance, etc. won't be providing any help. For context, the culvert that's there now is a 9 foot diameter by 38' long tanker car culvert. It's been more than enough for the last 6 years, and so far this year, in April and May the water was within inches of cresting the 8' wing walls, and then last Monday it went over the walls and then over the pipe by about 18". Looking for possible solutions, that will last, as they can't afford to keep throwing money at this when it could end up being temporary. Pic below for reference.
