Print Case Study
P.B.S. & J.
December 15, 2002 March 15, 2003
Officials at Houston Airport System’s George Bush
Intercontinental Airport in Texas determined that a runway
expansion was required to maintain and enhance the
airport’s ability to support connecting hub operations.
Two CON/SPAN® structures were chosen as the best
solution to help reduce airfield congestion and aircraft
delay and also accommodate forecasted growth in
passenger and cargo activity.
The use of CON/SPAN structures provided significant
construction savings over initially proposed conventional
structures. Each bridge consisted of four precast arch
spans that created four tunnels at each crossing. The two
larger, center tunnels carry traffic on the access roads while
the two smaller, outer tunnels carry only service vehicles.
Precast headwalls and full-height precast MurEbal® walls
were used to minimize construction time.
