Both lanes of Jayne Boulevard in Port Jefferson Station will be closed for construction work beginning Monday, according to the New York State Department of Transportation.

The work, which will continue until summer, will help complete the major reconstruction of the NY Routes 347 and 112 intersection, the transportation department said in a news release.

Transportation officials said the construction will improve safety and mobility for about 71,000 drivers and includes new jug handles designed to reduce travel delays, fuel use and vehicle emissions.
