Forest Park Bridges

  • Site One Bridge on Wildwood Trail

  • Site Two Lower Macleay Trail bridges

  • Site Three Bridge failure on Maple Trail

Project Overview

Thanks to funding from the voter-approved Parks Replacement Bond, this project will replace bridges at three locations on the Wildwood, Lower Macleay and Maple Trails in Forest Park. This project is also part of the RENEW Forest Park Initiative.

Project Updates

Trail closures are currently in place on the Lower Macleay, Maple, and Wildwood Trails. We apologize for this disruption to your enjoyment of Forest Park. The closure of both the Lower Macleay and Wildwood is necessary to complete all erosion-contributing activities such as excavation and trail building prior to the permit-mandated date of September 30. Additionally, due to the extreme weather in Houston, TX, we have had significant delays of bridge material shipments.


updated September 20, 2017


The Lower Macleay Trail will continue to be closed through mid-October 2017. A reopening date will be posted once available. Lower Macleay Park is still open for public use (grassy area under the Thurman Street bridge between the parking lot and the start of the trail).

The work to repair winter trail damage on the Lower Macleay Trail is completed. The contractor is now working on assembling the new bridge and finalizing trail improvements. The trail will re-open once this work is fully completed.

The Maple Trail segment is also under construction. This segment of trail has been closed already for several years due to the failure of the old bridge. Please respect the trail closure signage and use the detour routes for your safety.
The segment of Wildwood Trail  between the Upper Macleay parking lot (at NW Cornell Road) to the intersection with the Lower Macleay Trail is closed for bridge replacement. This trail is expected to reopen by the end of October 2017.

Summary of Expected 2017 Trail Closures for this Project:

  • Lower Macleay Trail will be closed from the Lower Macleay Trailhead to the intersection with the Wildwood Trail (by the Stone House) for 2-3 months. Access to the ADA-accessible portion of Lower Macleay Trail may be open to the public intermittently if construction allows for safe public access. 
  • Maple Trail will be closed between Firelane 4 and the Koenig Trail. This segment of trail has been closed to the public for several years, due to the failure of the old bridge. This work will take 3-4 months. 
  • Wildwood Trail will be closed between the Upper Macleay parking lot (at NW Cornell Road) to the intersection with the Lower Macleay Trail for up 2-3 months.
  • Additional PP&R trail closure information can be found here
