The long-term closure of State Route 315 in Delaware County begins Monday.
The work will be done in two parts. The road will be closed between Powell and Jewitt Roads for three weeks beginning Monday to clear trees and relocate utilities.
On January 30, 315 will close between Powell Road and Retreat lane so state transportation workers can build a stabilization wall along the Olentangy River.
ODOT recommends taking State Route 750 to U.S. Route 23 to Interstate 270 back to 315 as a detour.
