The TLR would have to cross the Caledonian Canal
Scotland's transport secretary said he was opposed to a new swing road bridge over the Caledonian Canal in Inverness.
Stewart Stevenson said other options will have to be considered for carrying the proposed trunk relief road (TLR).
New timetables have had to be introduced to the existing swing bridges at Tomnahurich and Muirtown in the city to ease congestion.
A tunnel and aqueduct have previously been proposed for the TLR, which would act as a bypass linking the A9 and A82.
Mr Stevenson ruled out another swing bridge during an announcement on the setting up of a steering committee between the Scottish Government and Highland Council to push forwards plans for the link road.
The bridges open to allow boats to travel along the canal.
There have been complaints from nearby residents and commuters that the openings cause traffic to build up on roads through Inverness.
Mr Stevenson said: "A further swing bridge is not helpful."
He added: "The council have their own financial provision and we want to make sure what we are doing compliments what they are doing."
