TxDOT
has several projects in-progress or upcoming along I-10 West
between Leon Springs and Boerne to improve intersections, add new
overpasses, and convert the access roads to one-way operation. This
page contains information about all of these projects.
The
overarching
goal of most of these projects is to convert the access roads to
one-way
operation from Leon Springs to Boerne. As this area becomes
more suburbanized, one-way access roads will be safer and more
efficient. For optimal operation, there needs to be
a crossover every mile or so. Otherwise, someone turning onto
a one-way access road just past an intersection and wanting to go the
opposite direction could have to travel more than
two miles out of their way; having a crossover every mile or so both
minimizes
this inconvenience and provides better access for emergency vehicles.
This is the reason why new overpasses at
Old Fredericksburg Road and Balcones Creek Road are planned (and is the
primary reason, by the way, that the overpass at
Dominion Drive was built several years ago, despite cynical
misinformation alleging otherwise.)
Note
that none of these projects will add any new mainlanes to I-10 itself. Planning
is underway for future projects to do
that.

At
SH 46 (W Bandera Road) |
There
are two projects at this location. A project to build a new
frontage road from Christus Parkway to SH 46 is wrapping up.
This project moved the westbound exit to SH 46 further
south
on the new frontage road and add a new westbound entrance ramp between
Christus Parkway and SH 46.
The
future project will overhaul and redesign the entire interchange here.
The
SH 46 overpass will be widened to two through lanes and a left turn
lane in each direction. The access roads adjacent to the
overpass will be re-aligned inward
toward the mainlanes and portions of the old access roads at School St.
and Upper Balcones Rd. will be converted to local access drives
configured to
minimize conflicts. A westbound to eastbound turnaround will
also
be
constructed. Although not shown on the schematic, the park and ride lot will kept and be reconfigured in its current location.
The
recent announcement of a
proposed Buc-ee's store about 1.5 miles south of this intersection has
accelerated TxDOT's proposed timeline for the future interchange
project. It has been let and should start construction this summer.
Westbound frontage road:
- This
project started in 2015 but was delayed due to performance
issues with the contractor
- Estimated completion: Early 2018 (currently 99% complete)
Interchange:
- Projected
start: Mid 2018 (will also include project #2 and part of #3 below)

At
US
87 Business (S Main
Street)
|
The
interchange will be completely redesigned into a more conventional
diamond intersection. A new, wider overpass will replace the
existing overpass and will end in a "T" at a realigned eastbound access
road. A new westbound
access road will
continue beyond the new intersection with US 87 and join with the new
frontage
road
currently under construction near Christus Parkway. There will be
turnarounds for both directions. The
existing entrance
and exit ramps will be relocated further south from the intersection.
The
recent announcement of a proposed Buc-ee's store on the west side of
this intersection has accelerated TxDOT's proposed timeline for this
project. It has been let and will start construction this summer. The final project includes modifications to accomodate a
planned City of Boerne thoroughfare running south from the new overpass
and the elimination or modification of the planned service drive in
that area.
- Projected
start: Mid 2018 (will also include project #1 above and part of #3 below)

At
Scenic Loop Road/Boerne Stage Road |
Current project:
Scenic Loop under I-10 is being
widened to accommodate turning lanes. To facilitate this, the
I-10 overpass is being
lengthened and
rebuilt higher to improve clearance. Additional turn lanes
will be
added on the access roads.
- Estimated completion: Spring 2018 (currently 90% complete)

Click above to see the schematic for
this project
Future project:
A future project will add
turnarounds in both directions, move the entrance and exit ramps, and
convert the access roads to one-way.
- Scheduled
start: The section north (west) of Scenic Loop Rd. is part of a single
project that includes #1 and #2 above and is set to start in mid 2018.
The section south (east) of Scenic Loop Rd. is currently TBA.

At
Balcones Creek Road/Dietz
Elkhorn Road |
A
new overpass for I-10 will be built at Balcones Creek Road. The
access roads will be converted to one-way and new access road bridges
over Balcones Creek will be built. The crossover
under I-10 will remain.
- Projected
start: Late 2018

At
Fair Oaks Ranch Parkway/Tarpon
Drive |
The
overpass will be widened to five lanes and realigned to join Fair Oaks
Ranch Parkway to Tarpon Drive. The access roads south of Fair Oaks
Pkwy will be converted to one-way and
the entrance and exit ramps will
be relocated. The future project at Balcones Creek Road
(above)
will then convert the access roads north of Fair Oaks Pkwy to one-way
and relocate those entrance and exit ramps.
- Project
currently underway
- Estimated
completion: Summer 2018 (currently 76% complete)

At
Old Fredericksburg
Road/Buckskin Drive |
A
new overpass for I-10 is being built at Old Fredericksburg Road
connecting it to Buckskin Drive. The access roads will be
converted to one-way, new entrance and exit ramps for this intersection
added, and the exit and entrance ramps for Ralph Fair
Road/Boerne Stage Road will be relocated.
- Project
currently underway
- Estimated completion:
Summer 2018 (currently 78% complete)
