For bridges that will remain coded U, FHWA recommends that a POA be developed and implemented until:
a) properly designed countermeasures can be installed to protect the bridge foundations
b) the bridge can be replaced
FHWA guidance is intended to offer a rational approach for:
a) determining enough about bridge foundations to conduct a scour evaluation, or
b) appropriately address bridges that will remain coded U
