If you’re planning any evening travel around the region for the rest of the week, you may want to keep an alternate route in mind.

Overnight roadwork will cause lane closures on both Highway 85 and Highway 401 in Kitchener and Cambridge, respectively.

The Ministry of Transportation says that Highway 85 will see nightly, alternating road closures until Sunday.

They began on Wednesday night.

Lanes will be closed in both directions for nightly construction from 10 p.m. to 6 a.m. from Frederick Street to Lancaster Street.

Highway 401 will also be affected in Cambridge from Fountain Street South to Townline Road in both directions. Nightly construction began on the right lanes on Thursday and will continue until Sunday.

The eastbound off ramp to Highway 8 will be closed from 11 p.m. on Saturday until 7 a.m. on Sunday.

The Highway 8 southbound off ramp to Highway 401 will be closed from Friday night until Saturday morning as well.
