New Circle Road between Versailles and Leestown roads will be closed in both directions for blasting at 10 a.m. and 2 p.m. starting Wednesday, according to the city's traffic management center.
The road will be shut down about 10 minutes prior to each blast, according to the city notice. New Circle will remain closed about 20 minutes.
In addition, Old Frankfort Pike will be shut down in both directions between Enterprise Drive and Duncan Machinery Drive.
The blasting is part of a nearly two-year project to widen New Circle Road from four lanes to six lanes between Leestown and Versailles roads. The blasting will occur on the 10 a.m., 2 p.m. schedule until further notice, according to the traffic center.

The speed limit was reduced to 45 mph on that stretch of New Circle during the project. Much of the work was scheduled to occur between 7 p.m. and 7 a.m. Friday night work was set to begin about 8 p.m.
The project includes a reconfiguration of 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.
