O?ahu motorists should expect traffic delays Sunday morning heading west from Hawai?i Kai to Wai?anae. 

Supporters of the protests against building of the Thirty Meter Telescope are organizing a cross-island convoy. Organizers expect several hundred motorists.

Honolulu police officers will escort the motorcade from Maunalua beginning at 9 a.m. traveling to M??ili by around noon.

They will start out on Kalanianaole Highway, then travel on the H-1 Freeway and Farrington Highway. On-ramps to the H-1 will be closed while the convoy is underway.

Convoy organizers are asking participants to arrive at Maunalua Bay by 8 a.m. for a briefing on the event’s kapu aloha or nonviolence code of conduct.
