Update 7/23/19 – ROAD CLOSURE NOTIFICATIONS – Windsor Harmony Road project to be closing the Harmony Road & Latham Intersection

  • The north side of the Harmony Road & Latham Parkway intersection will be closed 7/26-7/29 to allow for milling and paving operations in the intersection. 
  • The south side of the Harmony Road & Latham Parkway intersection will be closed 7/30-7/31 for milling and paving operations.
  • Additional details and a diagram of these closures can be found HERE

East-West traffic on Harmony Road will not be impacted.  Turning onto & from Latham will be restricted as noted, and traffic using Latham Parkway will need to follow the posted detour routes.

Note: This is a major improvement project being performed on a section of road that experiences very heavy traffic volume – especially during peak commute times in the morning and the late afternoon.  Delays should be expected and alternate routes are advised.

Project Overview

Phase 4 of The Harmony Road improvements Project will begin in January of 2019 and is expected to be completed in August of 2019.  Improvements involve the reconstruction and widening of Harmony Road from Three Bell Parkway to Latham Parkway (AKA: LCR 1 or WCR 13).  The new road section will have 4 lanes, bike lanes, raised landscaped median, and intersection improvements at Club Drive & Latham Parkway.

The majority of the roadwork will occur in Spring & Summer of 2019, however due to required work on the Lake Canal crossing that must happen before irrigation resumes in Spring 2019, there is some work that must occur during late winter/early spring.  Traffic impact should be minimal during the winter, but delays should be expected.
