The size of the creek would require a permit for the work in Ohio. For that amount of water, you also need to be aware of scour at the piers

Yikes! and amen on the scouring. Without knowing the specifics, bank conditions, flow, rise and fall, etc. I would guess you need some concrete abutments and some sound engineering. As others have said, you might be setting yourself up with a short term solution to get across. A project that big is one I wouldn't want to do twice! Good luck and I will be following this one... should be interesting!

Been doing some research into regs in NYS that may affect my projects and as my little stream is a C(t) designation it seems fairly certain for the OP that New York State does require a permit if the stream has a certain classification or higher. Better to know beforehand.

"A Protection of Waters Permit is required for disturbing the bed or banks of a stream with a classification and standard of C(t) or higher. For example, 1) the construction of a bridge or placement of a culvert to allow access across a stream; 2) any type of stream bank protection, e.g. placement of rip-rap, or other revetment; 3) lowering stream banks to establish a stream crossing (i.e. creation of a ford); 4) using equipment to remove debris in a stream, all require a permit.
Some examples of activities which are exempt from the requirement to obtain a Protection of Waters permit are:
1) agricultural activities involving the crossing and re-crossing of a stream by livestock or rubber tired farm equipment at an established crossing;
2) removal of fallen tree limbs or trunks where material can be cabled and pulled from the stream without disruption of the stream bed or banks, using equipment placed on or above the stream bank.
There are occasions when permits from other state or local agencies are required; county or town permits, flood plain permits or other approvals may be necessary. There is no charge for the Protection of Waters Permit. For permit applications and any questions regarding the permit process contact:

Here are some exact plans for an Agricultural bridge rated at 4 and 10 tons. To me, they seem way over engineered but I assume better minds were involved. There are some very good details that should be helpful. Good luck with your project it sounds like a huge undertaking.
