East side of the Lacombe Bayou Drawbridge to Neslo Rd

Starting Wednesday, May 18, 2022, a portion of the Tammany Trace, starting at the East side of the Lacombe Bayou Drawbridge to Neslo Rd, will be closed for repaving.

This project is expected to be completed by Summer 2022, weather permitting.

Signs were placed near the project limits on Monday, May 16.


The Trace from Jackson Ave and Clausel St. in Mandeville is closed:

Starting April 4, 2022, a portion of the Tammany Trace will be closed to the public due to a water line repair. This portion will be between Jackson Ave and Clausel St. in Mandeville.

We apologize for the inconvenience. Our top priority is to keep everyone safe during this repair project.

Please call Tammany Trace Trailhead at 985-867-9490 for more information.

Hwy 59 S-Curve Tunnel is currently closed.  

Riders and pedestrians will not be able to cross the highway at this time.  Please consider closures before planning trips on the Tammany Trace. The Tunnel is still barricaded and is not open at this time while repairs are completed.  Please do not move or go around the barricades.


Portion of Tammany Trace to Close for a Prolonged Period as I-12 Widening Project Proceeds

The widening of I-12 is currently underway. This is a significant infrastructure project through the DOTD in partnership with St. Tammany Parish Government. The safety of St. Tammany citizens while this project proceeds is paramount, and as such, as part of this project, a portion of the Tammany Trace in Mandeville will close beginning Monday, October 19, 2020, from the southern edge of the Little Creek bridge — to the northern edge of the Koop Drive Loop — approximately 560 feet. This closure is expected to last until the Fall of 2022 due to the construction overhead as well as equipment staging. Patrons will have access to the Tammany Trace at Dove Park, and at the Koop Drive Trailhead, however, there will be no access between these two points on the Trace. 

Trace patrons are asked to be aware of this closure. Any changes will be updated through our websites: www.stpgov.org, and www.tammanytrace.org. Thank you for your patience and understanding.
