Low bridge road signs covered

This road is a very narrow road with blind corners. 90% of the accidents are from the army men/women. The road signs to say there is a low bridge are covered and there is only 1 sign. Please could it be cleared so visible and more erected? Large lorries can’t get under the bridge and try and revers back. It is a huge dangerous hazard. This morning I waited for yet another lorry to reverse and other car users were overtaking not being able to see round the blind bend. There Will be another fatality on this road due to lorries not knowing about the bridge.
