October 15th, 2020 and recent project schedules. As always, some
may change prior to construction. This page will be updated again

US 90 West from Old

The initial phases are mostly funded and it is expected
construction could start in 2025 and 2028 (see below for details.) Future phases are
currently unfunded and therefore have no timeline.
project recently built the westbound to eastbound turnaround at
project will ultimately upgrade US 90 from Loop 1604 to west of SH 211
from a four lane divided
highway to a six lane freeway with access roads. It will
also revise the SH
211 interchange, add an additional lane in each direction between Loops
410 and 1604, and make various
operational improvements along the corridor from Loop 1604 to Old
Highway 90. A later phase of this project will construct the remaining
flyovers in the Loop 1604 interchange. A separate project will
construct the remaining flyovers at the Loop 410 interchange.
project is a continuation of recent projects that expanded the section between Loops 410 and 1604.
of the scale of this project, funding availability, and, more recently, inflation, it will be
broken into multiple phases. Presently, those phases are as follows:
- Phase 1: Expansion between Loop 410 and Loop 1604. This phase is expected to start in 2025.
- Phase 2: Expansion and upgrades between Loop 1604 and SH 211 and
the westbound US 90 to northbound Loop 1604 flyover. This phase is currently expected to start in 2028.
- Phase 3:
Ramp revisions and operational improvements between Loop 410 and Old
Highway 90. It is currently anticipated that this phase could start in
- Phase 4: Construct remaining flyovers at Loop 1604. This phase is currently penciled-in for 2034.
project will help
Several new large subdivisions have been constructed along US
90 west of Loop 1604 in the past decade with several more planned or
underway. As a
result, traffic volumes along that stretch of US 90 have increased more
than 70% over the past decade. Additionally, growth along the Potranco
Road corridor just to the north is likely contributing to traffic in
the US 90 corridor via SH 211 and Grossenbacher Rd. Upgrading
this segment to a freeway will allow it to more efficiently and
safely handle current and expected traffic.
the freeway between Loop 410 and 1604 will allow it to accommodate the
influx of traffic both from the west as well as from Loop 1604, where
growth is now occurring south of US 90.
Completing the Loop 1604
interchange will accommodate current and future traffic there stemming from the new growth south of US 90.
The operational improvements east of Loop 410 will adjust the ramps there to accommodate the future flyovers for the Loop 410
interchange and make other general improvements.
