"Creation
is messy work."
This
page contains information about current and future major freeway
expansion and
improvement projects in the San Antonio area. Minor
projects,
as well as maintenance and repair jobs, are
not
included (there's just not enough room to list them all here!) Data for
this
page comes primarily from official TxDOT, ARMA, and MPO project
databases as well
as from media reports and the author's personal
knowledge. All
information
is subject to change.
This
is not an official
website. The data on this page was last updated May 30,
2022.
Current
& near-term projects
The
following is a compendium of major San Antonio area freeway projects
currently underway or in advanced planning. The
numbers and letters on the map correspond to
the listings on the
table below. Letting,
start, and completion dates represent the latest estimates
that could
determined as of the date this page was updated.
In
the "advanced planning" section, projected start dates are either when
a
project is estimated to start construction if already funded, or when
funding
may be available for a project based on current funding
projections.
Project
schedules
are in a constant state of flux due to weather and other
factors
for projects already underway, and due to funding availability and
other red
tape for projects in planning. Therefore, all dates shown here
are
always subject to change.
How percentage
completed is calculated
The
percentage
completed shown below is computed by averaging the percentage of
allotted working
time used and contract budget amount used to date as obtained
from
TxDOT's website. This method
takes both
metrics into consideration and helps to smooth inconsistencies and the
"fits and starts" that
one
metric or the other can often produce as a project progresses. If that
average exceeds 100%, then the lower of the two metrics is used. If
that still exceeds 100%, the project will be listed as 98% complete.
Projects that have reached substantial completion but are still working
on final "punch list" items will be shown as 99% complete.
Occasionally,
TxDOT may grant extra time to complete a project due to issues beyond
the contractor's control. When this happens, you may notice the
completion percentage on a project decrease.
Because
I use my own method for calculating the completion percentage, it may
not always match information from other sources. In the end,
construction progress is always fluid and somewhat subjective, so any
advertised completion percentage should always be considered
approximate.
