DOT: Overnight closures on Route 347 in Hauppauge

A stretch of Route 347 in Hauppauge will be partially closed over a two-week span as part of a $30.5 construction project, the state Department of Transportation said.

Overnight closures leaving a single travel lane on westbound Route 347 between Mount Pleasant Road and Route 111 began Monday and run until Thursday, the agency said. A second closure runs from Tuesday, Sept. 2, to Friday, Sept. 5.

Each night from 9 p.m. to 6 a.m. the roadway will be restricted to one-lane of westbound travel, the agency said in a news release.

Traffic will not be subject to lane restrictions the Friday before the Labor Day weekend or on Labor Day, officials said.

The closures are needed as part of the $30.5 million, Design-Build, NY Route 347 Safety, Mobility and Environmental Improvement Project currently under construction, the agency said.

The project is a second in a series of NY Route 347 corridor projects planned to improve safety and to reduce travel delays "by transforming NY Route 347 into a modified boulevard and suburban greenway for 15 miles through Smithtown, Islip and Brookhaven," the agency said.

Up-to-date traffic and travel information is available by calling 511 or visiting 511NY.org. Motorists also can find information at informny.com and on their hand-held communication devices at informny.mobi.
