Temporary changes to the lifting schedule for Poole Bridge will be in place from Saturday 14 January 2012.
The 2.30pm and 4.30pm bridge lifts on Saturdays and Sundays will be cancelled and replaced with a single bridge lift at 3.30pm to allow the completion of work on the new Twin Sails Bridge.
The revised schedule will be in place until February 2012 when a new timetable will be implemented for the operation of a two bridge system.
Councillor Xena Dion, Cabinet Portfolio Holder for Transportation, Borough of Poole, said: "We are pleased with the progress being made in the final stages of construction and the revised schedule will help the contractor as the Twin Sails Bridge nears completion. Motorists will be alerted via the variable message road signs in the area. We apologise for any inconvenience that this temporary change may cause."
