Just a silly question.....
Is it the responsibility of the Federal government to maintain these bridges or the local county/city where the bridges are located?

IIRC Interstate highways are Federal entities. State & local jurisdictions get Federal funds to take care of maintenance & repair from gas tax/trust fund. However, the Congress allocates some of this money to bike trails and museums - which may come under the Parks Dept. Very complex - but taxpayers pay for everything.
Not a silly question. Roads and bridges are a state and local responsibility. Yes, the Interstate Highway system was 95% front-funded by federal dollars, but the management and maintenance of highways, roads and bridges, is a state job.
