Install a concrete retaining wall (even those precast blocks) and back-fill and then pave over top - that would probably last the 10 years til the new bridge is built.

As for a final fix, that sounds like a reasonable idea. One problem though... the wood frame section was originally built due to the soft soils at that point.
Longer term pre-loading might be required to provide for soil compaction. Otherwise the pavement might eventually dip quite severely.
But the final fix still does not address an interim solution during the construction period as discussed above.
