A nearly two-year project to widen New Circle Road began Tuesday night.
New Circle is being widened from four lanes to six lanes between Leestown and Versailles roads.
The speed limit is being reduced to 45 mph on that stretch of New Circle during the project.
For the next several weeks, lane closures will be in effect in that area, according the state Transportation Cabinet. The work is scheduled to be done between 7 p.m. and 7 a.m., although work on Friday nights is not scheduled to begin until 8 p.m., and some work could be done outside those times.

Because of the construction, traffic coming from Old Frankfort Pike onto New Circle will have to stop, and there will be no merge area.
As the project progresses to allow more merging room, those conditions will change, Transportation Cabinet spokeswoman Natasha Lacy said.
The project will also involve reconfiguring the ramp that takes traffic from Versailles Road to northbound New Circle. The current "loop around" ramp will be replaced with a new "flyover" ramp similar to an overpass, Lacy said.
The entire widening project is estimated to cost $53 million and is scheduled to be finished by September 2016.
Plans to replace the Leestown Road interchange with a double-crossover diamond pattern similar to the one at Harrodsburg Road have been postponed, Lacy said. She said funding is a problem.
