Box Culvert Connection to Existing Drainage Opening

[RFreund]

See attached.

This is an existing overflow drainage opening (the is no constant flow) through an existing 'enclosure wall'. They are now raising the grade for a bike path and now need a box culvert under the path. I'm looking for a good connection detail to the existing. I'm not sure what should be done to avoid corrosion issues? Or at least something to start with so I can sound half intelligent when going over it with the boss.

Thanks.

I have seen where a culvert is extended and the new culvert is a different shape, some bars are epoxied into the end, and then a CIP collar of sorts is cast around it. Its going to be buried correct, so it wouldn't matter too much on aesthetics.

Yes, it will be buried. Thanks for the suggestion.
