About 22,000 are expected to participate in the 26th annual Great Aloha Run from Aloha Tower to Aloha Stadium Monday, starting at 5 a.m.

The 8.15-mile course starts in Downtown, winds its way along Honolulu Harbor, down Nimitz Highway, Kamehameha Highway and into Aloha Stadium.

According to race co-founder Carole Kai Onouye, 19,300 civilians and close to 3,000 military have signed up.

Since 1985, the Great Aloha Run has raised more than $8.1 million and assisted more than 150 local non-profit organizations.

Most roads near the airport should be re-opened to cross-traffic by 8:30 a.m., and Salt Lake Boulevard between Kalaloa Street and Aloha Stadium should re-open by approximately 9:45 a.m.

Some traffic tips:

'Ewa-bound traffic to Downtown will be diverted onto South Street and from there use South Beretania Street to Punchbowl Street to get onto the freeway. Traffic on the elevated portion of the freeway should be light.

Avoid using the Middle Street and Dillingham Boulevard intersection, as delays on these streets may result from the closure of the Middle Street Interchange.
