Westbound Route 347 in Hauppauge is reopened after it was closed for more than three hours as volunteers from eight fire departments extinguished a brush fire in Bill Richards Memorial Park, authorities said.

The blaze started about 2:30 p.m., the third or fourth time firefighters have been fighting flames there in the past week or so, a Suffolk fire communications official said.

As many as 3 acres burned, he said. There were no reports of injuries, he said.

The westbound lanes, which were closed from the County Access Road to just east of where routes 347 and 454 split, were reopened about 5:50 p.m., Suffolk police said. Westbound traffic had been redirected to the state office complex on the other side of Route 347.

The blaze had been "slow burning" and caused extreme smoky conditions, adding to problems getting through the brush, the fire communications official said.

The Bill Richards Memorial Park is a small, wooded park on the north side of Route 347.
