Traffic Gridlock Leads City to Reconsider Evacuation Advice
HONOLULU COUNTY, HAWAII, JUL 31 – Officials say rush hour timing and over-evacuation caused severe traffic delays during tsunami warning; some tourists evacuated unnecessarily, complicating efforts, officials said.
- On Wednesday, Hawaii officials said over-evacuation by tourists worsened traffic congestion during the tsunami warning.
- Triggered by a magnitude 8.8 quake off Russia’s Kamchatka Peninsula, Wednesday’s tsunami warning was issued over more than 1,000 kilometers from Hokkaido, with waves arriving at least five hours later.
- Congestion peaked near downtown Honolulu when traffic crawled on S Beretania Street, and State Rep. Adrian Tam warned of dangerous gridlock in Waikiki with only four roads in and out.
- To manage flows, agencies sent police to key areas, used loudspeakers, blocked zones, and manipulated traffic lights, officials say.
- Officials plan to refine evacuation messaging, with Ed Sniffen saying he doesn't regret warnings but wants more guidance on managing evacuation timing.
