Project Overview

The Crabtree Creek and Black Creek Sewer Rehabilitation Project is coming to completion. Rehabilitation of sewer lines and manholes along the Black Creek Greenway has been completed between Dynasty Drive and the trailhead at Old Reedy Creek Road. Over the summer, contractors will complete the remaining work, including cleanup and restoration at the Lake Crabtree Dam and adjacent sewer easement (located outside the greenway) and removing the temporary bypass pipe. The good news is this will not require closure of the greenway and the trail is now open to the Public in its entirety.

Later this year, the Black Creek Greenway Renovation Project will get underway, restoring 2.5 miles of greenway from West Dynasty to Old Reedy Creek Road. The greenway will be upgraded to meet current greenway standards and elevated in flood-prone areas to improve trail resiliency. This work will be completed in phases, and the initial phase will be accompanied by construction of the Cary Parkway Pedestrian Bridge at Black Creek. The bridge will eliminate a 650-foot gap along Northwest Cary Parkway and will improve connectivity between neighborhoods, businesses, parkas and greenways.

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). Stay tuned for updates.

Greenway Detour Routes

During the sewer rehabilitation projects, greenway users may use detour routes that provide connectivity to commuter and recreational destinations. These detour routes will follow a combination of existing trails and roadways, and signage will be provided to guide trail users.
