Drivers in Renfrew County should expect delays on County Road 511 in Greater Madawaska.

Renfrew County says crews will be repairing a retaining wall from Calabogie Bridge North to Calabogie Road starting on Monday. The repairs are expected to continue into July.

While the road will stay open, it will be reduced to one lane at times.

The county is also reminding drivers that speed limits in construction zones are often reduced, and disobeying them can result in double the fine if workers are present.
