Veterans Memorial Drive at Scioto Darby Road closed April 30 and will remain closed until the first phase of the project is complete, according to city leaders.
The intersection eventually will reopen as a roundabout.
Deputy engineer Letty Schamp said she would not estimate when the road would reopen until utility relocation is quantified.
A detour to access the Hilliard Family Aquatic Center, community center, senior center, Sunrise Academy and the Hometown Urgent Care facility will be on an unnamed driveway through Roger A. Reynolds Municipal Park, west of the closure and east of Cosgray Road.
Scioto Darby Road west of Leppert Road will be reduced to one lane in each direction during the first phase of the project, Schamp said. Left-turn lanes will be eliminated at Moundview Drive, Hoffman Farms Drive, Darby Park Drive, Coventry Manor Way and the west park driveway into the municipal park, according to city officials.
The speed limit in the construction zone will be reduced to 25 mph.
