Dense fog and near-zero visibility turned a major crash on US 59 inbound near the IH 610 exit ramp into a serious traffic jam Saturday afternoon. The motor vehicle incident happened at 3:52 PM on May 23, snarling the South Freeway as heavy mist rolled across Harris County—visibility dropped to just 0.2 miles at the time of the wreck.
The crash came at an unusually busy moment for a Saturday afternoon. While this location typically sees most of its incidents during off-peak hours, the fog-shrouded conditions and the sheer volume of traffic using the US 59–IH 610 interchange meant backups built quickly. By the time crews arrived, multiple lanes were impacted and the southbound backup extended well beyond the immediate crash zone.
This particular stretch of US 59 has become a persistent trouble spot. According to LTA data, the corridor logged 76 incidents in the past 30 days alone—57 of them major crashes. Over the past 90 days, the number climbs to 233 total incidents, with 156 classified as major and four fatal. The 12-month picture is even grimmer: 298 incidents and 204 major crashes at this location in a single year. While this location does see crashes during rush hour (37% of incidents occur then), the dominant pattern is actually off-peak activity, suggesting congestion and visibility aren't the only culprits.
Weather played a clear role this afternoon. TxDOT reports wet conditions—which include fog and reduced visibility—contributed to over 14,000 Texas crashes in the most recent annual reporting period. On a Saturday afternoon when many drivers may be less alert, fog reducing visibility to one-fifth of a mile makes any wreck worse.
Crews cleared the incident and traffic resumed normal flow by late afternoon, but the incident underscores why Saturday traffic on this stretch demands extra caution, particularly when visibility drops. If you're heading toward the US 59–IH 610 area in the coming days, keep an eye on real-time incident updates—this corridor has a habit of catching drivers off guard.
