The City of Round Rock is planning for upgrades to Chisholm Trail Road between Sam Bass Road and RM 620. This project will include pavement reconstruction, sidewalk upgrades, and improvements to utility and drainage infrastructure.

Construction for the Chisholm Trail South Improvements project is anticipated to begin in July 2025 and last through summer 2026. During construction, detours will be put in place.

Project Update: January 2026

Construction has resumed.

Currently Atmos Gas has utility work at the north end of the project so our contractor is focusing on competing activities near the south end of the project.  As Atmos progresses with their work, our contractor will follow behind completing storm sewer construction.

The project is scheduled for completion summer 2026.

The City held an in-person neighborhood meeting on Tuesday, November 19, 2024, to share construction and detour information with property owners along the project limits. Materials shared at the neighborhood meeting are available below.
