Portions of H-1 and H-3 freeways between Honolulu Airport and the Windward side will be shut down this afternoon and again Tuesday night so Honolulu police can conduct escort training.

The first closure will take place from 1-2:30 p.m. today and again from 8-9:30 p.m. Tuesday. Both sides of the roadways will be closed.

Portions of Kaneohe Bay Drive will also be closed, police said.

Motorists are advised to avoid these areas and use alternate routes.

While the Honolulu Police Department would not disclose the reason for the training, President Barack Obama and his family are again expected to visit Oahu and stay in Kailua during the Christmas break.
