Drivers in and around Cornwall will have 13 National Highways road closures to watch out for this week.

But motorists will be able to take some solace in the fact that all of them are only expected to cause slight delays, of less than 10 minutes.

The latest expected works list, with notes from National Highways, shows that five closures already in place are expected to carry on this week:

• A30, from 8pm August 21 to 4am August 22, slight delays (under 10 minutes): A30 eastbound, Innis Downs - lane closure for barrier/fence safety repairs.

• A38, from 8am to 2pm on August 22, slight delays (under 10 minutes): A38 westbound, Lower Clicker lane closure for barrier repairs.
