Police in Nairn are offering advice to motorists who use the Whitebridge on the B9090 between Clephanton and Cawdor.
The bridge, which crosses the River Nairn, has an 18 tonne weight limit, which has been in place since April 2016.
Officers have received a number of complaints from the local community about large lorries and goods vehicles suspected of breaching the weight limit.
In effect, vehicles designed to transport loads where the maximum permissible weight of a tractor and trailer combination exceeds the 18 tonne restriction are not lawfully permitted to cross the Whitebridge, irrespective whether they are laden or not.
Local officers and officers from the Road Policing Unit are being deployed to enforce the weight restriction.
The minimum penalty is a fixed penalty notice for disobeying traffic signage - while any offence could also be reported to the Procurator Fiscal for consideration of court proceedings or referral of vehicle operators to the Traffic Commissioner's office.
Nairn-based Sergeant Graeme Erskine said: "Vehicle operators and drivers of HGVs are asked to give due consideration to the weight restriction on the Whitebridge and help to maintain the structural integrity of the bridge and the safety of other road users.
"The Highland Council has identified a preferred diversion route for vehicles with a maximum gross weight exceeding the 18 tonne restriction, avoiding the Whitebridge via the A96, A939 and B9101 roads and we urge all drivers to stick to that route.
"We will take action against anyone found to be exceeding the weight limit. The few minutes potentially saved in journey time are not worth the risk of the potential penalties which could be imposed.
"Anyone with information or concerns about use of the bridge can contact us on 101 or call Crimestoppers on 0800 555 111 if you prefer to remain anonymous."
