Work is continuing to twin the Trans-Canada Highway west of Kenora.
But that may mean some delays for motorists.
Moncrief Construction (MCL) says it will be blasting for six kilometers east of the Ontario/Manitoba border for the next for the next four months.
Blasting will take place five times a day and during those times, both lanes of Highway 17 will have to be closed for up to 15 minutes.
Moncrief says traffic delays will vary in duration based on traffic volumes at those times.
Blasting will take place until November 22nd.
