NASHVILLE (AP) - The Transportation Department is making sure travelers on Tennessee highways aren't delayed by road construction over the Labor Day weekend.

The department is halting all lane closure activity on interstates and state highways beginning at noon on Friday through 6 a.m. on Tuesday.

Transportation Commissioner John Schroer says AAA predicts Friday and Monday to be the busiest travel times during the Labor Day holiday weekend.

While lane closure activity will be stopped, officials say workers will still be on site in many construction zones, and drivers are urged to obey posted speed limits.

Drivers convicted of speeding in work zones where workers are present face a fine of up to $500, plus court fees and possible increased insurance premiums.
