Post Oak Trail Project

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 II - October 9, 2023 to December 11, 2023

Beginning Monday, October 9, 2023, at 7:00 a.m., the northbound lane of Post Oak Trail between Silver Spur Trail and Rolling Acres will be closed while the contractor begins pavement widening. During this phase of construction, traffic will be reduced to one lane allowing only northbound traffic, as seen in the diagram below. Northbound traffic will be driving on the southbound lanes. This phase of construction is expected to be completed in late December, weather permitting.

Service Update: Residents in the work zone of Post Oak Trail, take note of changes to mail delivery and refuse pickup services. On Monday, October 9, please place all refuse bins in normal pickup locations by 6:00 AM. Beginning on October 16, residents in the work zone should place all bins at the edge of the work zone by 6:00 AM on Monday mornings. Republic Services or City staff will move empty bins back to driveways.

The traveling public should expect delays during construction and plan travel routes accordingly. Follow the detour signs to avoid confusion. When traveling in a work zone, remain vigilant, watching for large equipment and crewmen. 

Please direct any questions or concerns to San Antonio District Public Information Officer, Tanya Brown at tanya.brown@txdot.gov or (512) 658-5177.

Phase III - Starts on December 12, 2023 

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.

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.
