The Long Island Expressway is lightening up.
A project that began Tuesday night will replace almost every highway sign with more-reflective versions, eliminating the need to light the signs, state Department of Transportation spokeswoman Eileen Peters said Tuesday.
"Not only will we no longer pay for the electric costs of illuminating signs, we'll no longer need to close lanes and inconvenience motorists while we service burned-out or weather-damaged bulbs," she said.
Crews began at the Queens border and will work eastward to Riverhead, then back on the westbound side, with plans to have the work finished by the spring, Peters said. The project will require full overnight closures of several-mile-long sections of the LIE as the work progresses.
Once the LIE project is finished, the same sign-replacement work will take place on sections of the Northern State, Southern State, Meadowbrook and Sagtikos parkways, Seaford-Oyster Bay Expressway and Robert Moses Causeway, for a total project cost of $7.4 million.
The work schedule may be changed as weather requires.
Eastbound LIE closures will take place between 11 p.m. and 6 a.m. and the westbound closures will occur between 10 p.m. and 5 a.m. on weekdays.
When the work moves east of Jericho Turnpike at Exit 40, some lane closures may be necessary between 10 a.m. and 3 p.m., according to the DOT.
State road crews this week completed repairs to lighting outages on the Southern State Parkway between Eagle Avenue (Exit 18) and Peninsula Boulevard (Exit 19), Peters said. A rotted cable had left that section of roadway in the dark.
