Size doesn't matter - any wildfire can halt highway traffic for any given time.
From the Source:
"Firefighters battled two brushfires in West Oahu Thursday afternoon.
The first sparked at around 12:25 p.m. in Makakilo. Officials say the blaze was about a half-acre in size and contained in less than 30 minutes.
While no structures were threatened, Honolulu police shut down two right west-bound lanes of the Makakilo Drive off-ramp from the H-1 Freeway for a short period.
Then at 1:35 p.m., another brushfire was reported, this time in Kunia.
Officials say it was also a half-acre in size and contained in about 30 minutes.
Flames and smoke came close to roads, however no road or lane closures were issued.
Officials say no structures were threatened and no property was damaged."
