Herb Gray Parkway constructors have received extended exemptions under noise bylaws in LaSalle and Tecumseh.

It's not just machinery and heavy equipment that nearby residents will soon be hearing for longer periods of time.

The parkway group plans to start using bird bangers to scare off geese on the construction site.

That's because prairie grass seeds will be planted along the new road and there's a concern geese will eat the seeds.

"Apparently, the seed is very expensive ... and something Canada geese like munching on," LaSalle Mayor Ken Antanya said.

"It sounds like a firecracker. It's to discourage them from settling on those areas and using that as feeding grounds," Lakeshore Mayor Gary McNamara said.
