after the closing of Kelly AFB in 2001, then recovered a bit as
logistics operations opened at Port San Antonio, but have stagnated in
recent years even with the new development there..

Construction projects
No
current projects in
this corridor.
Future plans
Over
the past two decades, the
former Kelly AFB has been converted into a major industrial park and
inland port named Port San Antonio (previously named
KellyUSA.) As Port San
Antonio grows, traffic in and around the area has grown and is expected
to continue to do so. Therefore, part of
the redevelopment plans included the proposed construction of an
expressway (Kelly Parkway)
connecting US 90 with I-35 South,
Loop 410 South, and SH 16 South; Spur 371 would comprise
the
northernmost
section of that corridor. Improvements to the interchange at
US 90 would be
included. However, there is presently no timetable or funding
for those
projects.
History
Authorized
by Minute
Order 51835 (September 25, 1962). It
originally had the
unimaginative
title of "Kelly Access Road", but its name was changed to General
Hudnell
Drive shortly after it opened. Major General William Hudnell
retired as
commander of Kelly AFB in 1965.
- September 1964:
Construction began with a
ceremony attended by 500 people. The "groundbreaking" was
done using an
oversized plunger that detonated a simulated missile warhead,
ostensibly symbolizing the importance of access to Kelly AFB to the
nation's security during the Cold War.
- 1967: Freeway was
completed and open to traffic.
