Project Overview

The Town of Cary has been rehabilitating major sewer lines that have reached the end of their service lines along the Crabtree Creek and Black Creek Greenways. The rehabilitation work is essential so that the Town can maintain its infrastructure and protect the environment. Work along the Crabtree Creek Greenway was completed in the summer of 2022. Sewer rehabilitation work along the Black Creek Greenway is being conducted in two phases. Work along the first phase between Dynasty Drive and North Cary Park has been completed and the second phase is now underway between North Cary Park and the Crabtree Creek Greenway. This will require closure of the Black Creek Greenway in this area until the Spring of 2023.

In addition, following the Black Creek sewer rehabilitation, the greenway will then undergo a renovation project, restoring 2.5 miles of greenway from West Dynasty Drive to Old Reedy Creek Road. The greenway will be upgraded to meet current greenway standards and elevated in flood prone areas to improve improving trail resiliency. This work will be completed in phases, beginning in 2023.

The single most important strategy is to minimize trail closures, impacting only one greenway at a time and deploying detour routes for greenway users. These projects involve careful sequencing so that greenway closures can be minimized. Information about trail closures and trail detours are provided (see further information below).
