A sinkhole that forced the closure of a portion of Dallas' White Rock Trail this week has stabilized, but city crews will continue to monitor the area for any shifting or ground movement. The sinkhole, which is 14 feet deep and roughly 4 by 6 feet at the surface, appears to have been caused by a deteriorated and abandoned 36-inch wastewater pipe. The city has reopened the trail but may need to close it again in the future to complete additional work and fill the abandoned pipeline with grout.
Why it matters
Sinkholes are not uncommon in Texas, and this incident highlights the ongoing infrastructure challenges cities face in maintaining public spaces and trails. The White Rock Trail is a popular recreational area, and the city's quick response and continued monitoring aim to ensure public safety.
The details
City crews discovered the sinkhole last Friday and have since backfilled it and restored the surface with compacted soil. Dallas is spending millions to address erosion along the trail after a 2024 report found 1,100 feet of shoreline along Garland Road is eroding and will fail without intervention. As a precaution, the Dallas Running Club is looking into rerouting its April race, the Tal Morrison Half Marathon, due to the sinkhole.
- The sinkhole was discovered by city crews last Friday (March 8, 2026).
- The portion of the trail along Garland Road near East Lawther Drive was reopened to the public on Thursday (March 13, 2026).
- The Dallas Running Club is considering rerouting its April race, the Tal Morrison Half Marathon, due to the sinkhole.
