  • Phase 1: Under construction (74% complete)
  • Phase 2: Unfunded

  • Phase 1: Construction began in July 2021 and is expected to be completed in mid 2025.
  • Phase 2: Currently no timeline pending funding.

  • The flyover from northbound Loop 410 to eastbound I‑10 opened on July 31, 2023.

Project description

This $450 million project will replace the existing obsolete cloverleaf interchange at I‑10 East and Loop 410 with a five-level interchange with flyover connectors and continuous access roads through the interchange on both I‑10 and Loop 410. Those access roads will intersect at signalized intersections within the interchange (similar to the Loop 1604/US 281 or Loop 410/SH 151 interchanges), allowing for full local access in all directions.

Phase 1, costing about $166 million, includes the following:

None of the existing ramps in the cloverleaf will be removed in Phase 1; however, the movements that remain in the cloverleaf should see substantially improved operation as the traffic using the new flyovers will no longer be using the cloverleaf, thus reducing weaving conflicts in several areas.

The remaining flyovers will be built in a future phase. In addition to the main interchange, that future phase will also make the following major improvements along Loop 410 north of I‑10:

The following additional improvements elsewhere in the vicinity will also be made:

How this project will help

These interchanges are over 50 years old and are now obsolete. Growing traffic volumes in these corridors, including increasing truck traffic from the numerous nearby warehouses, is straining these old interchanges. The new interchanges will accommodate current and future traffic volumes and improve safety.

The new underpass connecting WW White to Cornerway will improve local circulation by providing a new route to northbound Loop 410 from WW White and to southbound Loop 410 from the Cornerstone industrial park. Building this new intersection as a DLT will help it accommodate expected traffic volumes well into the future.

Adding the new continuous frontage roads and turnarounds through the I‑10/Loop 410 interchange, along Loop 410 near FM 78 and WW White, and also along I‑10 westbound near WW White will provide improved local access and allow more optimal placement of entrance and exit ramps in the area. Adjusting other ramp locations in the project area will bring them to modern standards and improve traffic flow and safety.
