1604 from I-35 to FM 78
planned (see timeline below)
This project will upgrade Loop
1604 at this location from a partial freeway to a full
freeway. This includes adding access roads between Kitty Hawk
and FM 1976 and extending the existing truncated northbound access road
between Kitty Hawk and Palisades; these new access roads will disconnect
the six "right-on, right-off" intersections along those
stretches from the mainlanes and connect them to the new access roads instead. The new access roads
will be "stubbed" for a future extension of them over the railroad
tracks at FM 1976/FM 78. The addition of the access roads
will eliminate the southbound entrance from and northbound exit to FM
1976; motorists in both cases will have to travel to Kitty Hawk and
The project will also reconfigure entrance and exit ramps,
add auxiliary lanes between ramps near Pat Booker, widen the Kitty Hawk overpass,
and reconstruct the Pat Booker overpass. The mainlanes between Pat Booker and Kitty Hawk will be
reconstructed and shifted toward each other in the median with a
concrete barrier built to separate them.

Traffic is increasing on this stretch of
Loop 1604 and the "right-on, right-off" intersections pose safety
issues for through traffic on 1604. These intersections will
be moved to the new access roads. The addition of auxiliary
lanes will help improve traffic flow and safety and the reconfiguration of the
ramps will bring this section in line with current design standards. Furthermore, future plans are to upgrade Loop 1604
south of FM 78 to a freeway, so upgrading this transitional section is a
This project is scheduled to break ground in late 2018.
- Why will the NB exit to FM 1976 and SB entrance from FM 1976 be removed?
"jug-handle" ramps there are obsolete and too dangerous for the
expected traffic volumes in the area. The traffic counts for
those movements were likely too low to warrant replacing those ramps.
- How will traffic that used to use the "jug-handle" ramps get to/from FM 1976?
both cases, that traffic will need to go north to Kitty Hawk and use
the turnaround or find alternate routes on other nearby roadways.
- Will a sound wall be built along the NB access road between Kitty Hawk and Palisades?
TxDOT will study this and determine if that location meets the criteria for a sound wall.
