Advanced planning (see timeline below.)
$450 million project will replace the existing obsolete
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
the interchange (similar to the Loop 1604/US 281 or Loop
151 interchanges), allowing for full local access in all directions.
addition to the main interchange, this project will also make the
following major improvements along Loop 410 north of I-10:
following additional improvements elsewhere in the vicinity will also

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.
to the size of this project, it will need to be done in phases.
Currently, there are two planned phases with the first phase expected
start in mid 2021. The second phase is currently unfunded.

however, the turning movements that remain in the cloverleaf
will benefit from the new flyovers
