The 1,000-year-old bridge at Tarr Steps which was washed away in the Christmas floods is in line to be re-built.
Around three-quarters of the clapper bridge, which crossed the River Barle, were swept away by the raging waters at the weekend.
Exmoor National Authority, English Heritage and Somerset County Council are looking at rebuilding the bridge as well as repairing damage to numerous other public rights of way in the area.
But the work needed is likely to cost more than the annual funding currently available to maintain public footpaths.
The damage is currently being assessed in more detail but it is thought the repairs are likely to cost thousands of pounds.
Fallen trees have also affected footpaths and bridleways, there have been landslips and surfaces have been washed away.
Local people and businesses have come forward to pledge funds to help with the repairs.
CareMoor for Exmoor, the Conservation and Access Fund for the National Park, had recently committed funds to improving the information available to the public in the Tarr Steps area, which will now require extensive work following the floods.
Dan James, Sustainable Economy Officer at the National Park says: "For residents and visitors alike, the path network is an important part of enjoying Exmoor National Park and we are keen to get things back to normal as soon as possible."
