Texas Department of Transportation
  • Upcoming construction improvements to the I-69 Southwest/I-610 West Loop Interchange Reconstruction in Harris County
  • Utilities work has already started; construction and detour and major lane closure activities begin February 2018
  • Construction is expected to last approximately six years
  • Project cost: $259 million; $87.5 million is Texas Clear Lanes funding
  • The project includes:
    • Reconstructing one-lane connectors to two-lane connectors
    • Upgrading interchange to current design standards
    • Adding shoulders on I-610 West Loop mainlane bridge
    • Increasing vertical clearances
    • Increasing sight distances
    • Adding detention ponds
    • Eliminating major weaving
  • The purpose of the project is to improve safety and mobility and reduce congestion
  • The project also addresses several needs, including one-lane direct connectors that are over capacity; projected growth would increase demand; and there are no shoulders, low vertical clearances, below minimum sight distances, and crashes in merge areas
  • I-610 West and I-69 South are heavily congested during peak hours (I-610 West Loop is ranked as the #1 Most Congested Highway in Texas)
