Plans call for widening connector ramps to two lanes, increasing sight distances, solutions to eliminate weaving, adding shoulders to the West Loop bridge and the addition of retention ponds.

Construction will include night time and weekend closures, officials said.

Here are some things to know about the project:

Estimated cost: $300 million

Estimated time to complete project: 5 years

When will work start?

  • Utilities work has already started; construction and detour and lane closure activities begin December 2017.

The project includes:

  • Reconstructing one-lane connectors to two-lane connectors
  • Upgrading interchange to current design standards
  • Adding shoulders on I-610 West main lane 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 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 #2 Most Congested Highway in Texas).
