Look into soil compaction grouting. Hayward Baker does this, and may have a branch near you. This is the least intrusive method to raise a structure. A small diameter pipe is pushed into the ground below the structure to solid bearing (as evidenced by refusal), then a pillow of grout is pumped in, the pipe is raised and another pillow pumped in, and so on. This compacts the soil around the grout and builds a column of grout. I watched a 2 story brick on stone footing addition in Denver close a 2” gap at the top, and the doors all worked! The other way is by excavating to the base of the footing and install a helical pier down to firm bearing (again as evidenced by refusal and installation torque), and then a bracket installed on the base of the footing, which has a jack plate to jack the structure up, and the bracket locked down. This requires digging to the base of the footing, which clearly won’t work in a bridge.

In a property in Oregon ther is 18' bridge, fairly wide, for vehicular traffic as well.
Due to action of a stream it spans, one end of it has sunk visibly.
I am aware of only two ways of fixing it:
1. Lift the end and push something (?) underneath.
2. Inject into the ground one of those swelling liquids,
which I was once told, have this capacity.
Do those two methods work?
Is there a better way?
