The first of a number of closures of the Princes Highway kicks in this Sunday (July 21) night 30 km north of Bega.
The shut down of the Dry River Bridge at Quaama is the first step and a round of essential maintenance works that started in late June and will roll through until early August.
NSW Roads and Maritime Services says the bridge bearings will be replaced to increase its life and reduce further maintenance costs.
To prepare, crews will be testing equipment this Sunday, (July 21) between 7 pm and 11 pm, weather permitting. No vehicles or pedestrians will be permitted to cross the bridge during this time.
Motorists are advised to avoid travel during the closure.
Emergency services located north of the Dry River Bridge will be able to access Quaama during the closure and in the event of an emergency, residents should always dial triple zero (000).
Work to replace the bearings will be carried out from Sunday, August 4 for two weeks on weeknights from Sundays to Thursdays, between 7 pm and 5 am, weather permitting.
The Dry River Bridge will need to close to traffic each night during this two week period between 7 pm and 9 pm while the bridge is lifted to allow crews to safely work under the structure, and then from 3 am and 5 am each morning as the bridge is brought back down to its standard height.
Outside of these closures, Dry River Bridge will operate as a single lane during work hours under stop/slow traffic control.
Single lane closures may also be in place outside of work hours as required and motorists are advised to check electronic message boards for additional traffic changes.
Reduced speed limits will be in place throughout the worksite at all times.
