Post Oak Trail Project

A contractor with the Texas Department of Transportation will begin a widening and safety improvement project on Post Oak Trail, between Silver Spur Trail and Rolling Acres Trail in the City of Fair Oaks Ranch, beginning Monday, September 25.

The project will widen the existing ten-foot lanes to eleven-foot lanes with three-foot shoulders for safety, as well as and installing cross-drainage structure improvements. Towards the completion of the project, the contractor will stripe and add delineators for improved visibility.


The $2,147,579 project was awarded to Capital Excavation Company of Buda and the estimated completion date is Summer 2024.

Post Oak Trail will be reduced to one way traffic northbound, requiring the traveling public to detour and follow a new traffic pattern during construction. Portable message boards, as well as detour signs, will be placed in the area to notify the traveling public of the work zone and to help motorists navigate through the work zone. Motorists are asked to obey traffic signs, reduce their speed, watch for large equipment, and crew members.

Phase III

The contractor has finished placing and compacting base material for the northbound lane. Beginning Tuesday, December 5, 2023, the contractor plans to start the chip seal application and on December 12, 2023, transition to Phase III of the project which involves moving traffic to the northbound lane while they start construction on the southbound lane. Please see the exhibit below showing upcoming service changes once Phase III starts.

Phase III Update for Residents
Since the contractor will be removing all existing mailboxes in Phase III to accommodate the road widening, please remove any decorative numbering or features you would like to salvage by the end of November.  During this period, temporary mailboxes on barrels will be placed on the east side of Post Oak Trail for each residence. Any remaining decorative numbering or features will be removed by City staff and potentially reused when the City reconstructs all custom mailboxes after the road work is completed. 


As a reminder, construction work begins at 7:30 each morning. If you have specific needs, please contact the contractor’s Superintendent, Jesus (Tavo) Marquez, at 512-801-1343 to coordinate your situation with construction activities. Your patience and cooperation during this vital construction project is much appreciated.
