US59 (Southwest Freeway
and Eastex Freeway)
Last updated August 2000
I-10 interchange, downtown Shepherd to Mandell, just southwest of downtown
Houston See location map
US 59 has been under intensive construction since 1989, when the section of the Southwest freeway from Shepherd (a few miles
southwest of downtown) to BW8 SW was widened. It took most of the
1990's to rebuilt the Eastex freeway from downtown to IAH. Current construction in progress focuses
on the far southwest and northern segments, as well as a central
segment. Starting from the southwest and going northward, current activity is summarized in
the table below.

I-10 Interchange
This is a major reconstruction of the US59/I10 interchange and expansion of
US59 to provide a distribution system into downtown.

Photo
taken June 2000, looking northward towards the 59/10 interchange. The existing
US 59 facility is the second structure from the left. At the time of this photo,
the southbound traffic had been diverted to a new structure (1st on left), and
the northbound traffic was diverted to the old southbound lanes.
As the photo suggests, this is a major expansion. All the ramps are intended
to distribute traffic onto the downtown streets. I took the photo from one of
those new ramps. Not shown in this photo are the new direct connectors to I-10,
which actually follow a path far away from the main freeways and cut through a
warehouse district.
Shepherd to Mandell
This section of freeway is currently 10 lanes and
depressed in a trench. The expansion project will widen the trench to add two
new HOV lanes. This is definitely NOT a California-style HOV project (where HOV
lanes are taken from the interior emergency lanes) !
The most interesting feature of this project is the four long-span arched
bridges over the trench. The existing cast-in-place concrete spans with center
supports are being removed and replaced with 217 ft (66m) long single spans.
This will allow flexibility in the configuration of the 10 main lanes and 2 HOV
lanes.
In 2001, a second $58 million contract will be let just east of the section
currently under constrution. The existing elevated main lanes just will be
demolished and the freeway will be placed in a trench. This will be a difficult
construction project, which will likely cause severe traffic disruptions.
Originally, TxDOT planned to add a second elevated deck for HOV to the
existing elevated freeway. The local neighborhood is high-income and very "inner
loop" (read liberal and anti-freeway), so they wanted nothing of the second
elevated deck. The next proposal was to make the existing deck wider to
accomodate the HOV lanes. This was feasible, but right-of-way was severely
constrained on the north side by a historic structure and on the south side by
high voltage lines. The neighborhood still wasn't happy, because they really
wanted to get rid of the elevated freeway. A leading candidate under
consideration at that point was to put the freeway in a cut-and-cover tunnel.
Fortunately, the cost eliminated that option. The final plan places 59 in a
trench. There is talk of building a "signature" bridge where Montrose will cross
the trench.

Looking west, this is the freeway trench in June 2000 during a closure for bridge
demolition. Four existing bridges are being replaced with single-span arched
bridges. One of the old bridges is shown in this photo.

2000 bridge installation at Mandell street, looking east.
 As
of June 2000, two arched bridges were in place. There will be a total of four in
this project. The next project to be let in 2001 will add two more arched
bridges. This view is towards the west.
 This
photo was taken in August 2000 during the freeway closure for the installation of the
last of the four arched bridges. This view looks west.
 This
is the existing 10 lane elevated freeway that will demolished and placed in a
trench. Tentative project letting is 2001 for this $58 million project.
 This
is the existing bridge at Montrose Blvd. Montrose is the main roadway to and
through the Museum District, and neighborhood interests considered the overpass
to be a detriment to the Museum District gateway. The freeway will be placed in
a trench, and there is talk of building a "signature" bridge over the
trench.
