Construction on the Bowes Street train trestle will halt on March 6 before resuming next week.
Parry Sound officials say additional work will occur at the trestle from March 13 to March 20.
The work will continue to require alternate lanes of traffic to be closed.
The sidewalk between Louisa Street and River Street will also be closed during this time frame.
Motorists and pedestrians are encouraged to use caution when travelling through this area.
