Failing culverts pose serious hazards to drivers, businesses, and rail traffic. It is incumbent upon design engineers and owner-managers to ensure structures are sound and reliable. DOT, county, municipal, and railway maintenance and engineering divisions play a critical role in conducting routine inspections and repairs.
Many repairs must be accomplished with zero to minimal impact on businesses, residents, and traffic – whether military, interstate commerce, county and municipal, or rail. And further complicating some repairs is the need for environmental sensitivity, for instance, when fish passages are involved.
This design guide will feature two separate projects requiring heavy load rating repairs, without closures to above ground road and rail. One of these cases also illustrates precautions implemented to protect a recognized trout stream.
