Under construction (0% complete)
project will widen the I-10 mainlanes from four lanes (two each way) to
six lanes (three each way), reconfigure the intersection at Graytown
Rd., raise the overpasses at Loop 1604, adjust entrance and exit ramps,
and convert the access roads to one-way.
project essentially extends the work being done between Loop 1604 and
than raising the I-10 overpasses over Loop 1604, this
project does not make any changes to the Loop 1604
interchanges; a future project will add elevated connectors (flyovers)
project will help
section of I-10 has experienced significant traffic growth over
the past decade and the adjacent area is beginning to see increasing
development, so the additional lane in each direction should
accommodate anticipated traffic volumes for the next couple of decades.
This project also dovetails on a statewide plan to expand all
I-10 between San Antonio and Houston.
Construction started in February 2020 and is
