A meeting of the steering group was held on Wednesday evening, where updates were given on progress.
And concerns were raised that as the weather improves the water level of the river will drop, exposing the remains and making them more inviting for exploration.
Speaking yesterday, Annandale South Councillor Sean Marshall said: “With the warmer weather, there were concerns that the remains of the bridges will be a magnet for youngsters.
“There was frustration with the delay, but they accept it’s not the council, it’s the protracted process involved. The council has been delayed more than they expected by this.
“We all agreed that it would be abhorrent if any land owner was seeking any financial gain from this, I would be disgusted if any landowner wanted any financial gain.”
The group now has a constitution fully in place, allowing them to open a bank account and push ahead properly with fundraising.
They will next meet on May 3 at 7 pm in the Anglers, all welcome.
