W129-00-00 Channel Modifications

The third and final phase of the Harris County Flood Control District's $14.4 million W129-00-00 Channel Enclosure Project began construction in 2018. The project's purpose is to improve the stormwater-carrying capacity and public safety features associated with a poorly functioning drainage channel, formally identified as HCFCD Unit W129-00-00, which runs adjacent to the Union Pacific Railroad tracks just inside West Loop 610.

The Flood Control District recognized the need for repairs to W129-00-00 and launched a three-phase reconstruction project in 2004 to rebuild and partially enclose the channel. Already completed phases one and two included enclosure of the existing drainage channel in dual 12-foot by 10-foot reinforced concrete box culverts from its confluence with Buffalo Bayou downstream to San Felipe Street, and then from San Felipe Street to Richmond Avenue, including the demolition and replacement of 50-year-old bridges that cross the drainage channel at Westheimer Road and at San Felipe Street. 

The third phase spans the section of channel between Richmond Avenue and Westpark Drive. In November 2017, Harris County Commissioners Court awarded the construction contract to BRH-Garver Construction LP. On January 8, 2018, the Flood Control District issued a notice to proceed with construction. Construction is expected to last through Summer 2019.

Current Status

The Flood Control District began construction in early February, 2019, along the northbound lanes of the US 59 frontage road at the W129-00-00 ditch. The northbound frontage lanes were temporarily closed. Detours through the area will be via Newcastle Street, Westpark Drive and Weslayan Street, as shown in this graphic:

  • For approximately 3 weeks, the northbound feeder will be closed on either side of W129-00-00 to allow for the removal of bridges from the northbound lanes of the US 59 frontage road and replacement with dual 12’x10’ reinforced concrete boxes (RCBs). The duration of the closure is weather dependent.
  • Signs announcing the closure have been installed in the area.
  • Once work on the northbound feeder has been completed, the lanes will be reopened and the southbound feeder will be closed on either side of W129-00-00 for approximately 3 weeks.

Motorists are encouraged to be alert, to pay attention to all posted street and lane closures and to take an alternate route.
