“Before we started the preliminary engineering, we had the roadmap of what we were going to
build,” Mr. Barnard says. “In a design-build environment, every day of delay is a lot of money. We
wanted to move the approval risk out of that process.”
To meet cost, design and engineering requirements, the team settled on a cable-stayed bridge
design. High in the middle and low at the ends, the design would
accommodate the Willamette River’s heavy marine traffic. In addi-
tion, a travel-demand model showed that the intended 12-foot
( 3.7-meter) width of the bicycle-pedestrian paths would have to be
increased to 14 feet ( 4. 3 meters) to accommodate the projected daily
use of 8,000 bicyclists and 3,000 pedestrians.
Construction began in December 2010 and ended exactly four
years later, on time and on budget, Mr. Barnard says. The bridge will
open in September, once the light-rail, bus and streetcar operators
have completed an extensive training program.
Right of Way
In the area surrounding Dallas-Fort Worth in Texas, USA, multiple municipalities have come together to build a better bike path.
The Fort Worth to Dallas Regional Trail project will connect 64
miles (103 kilometers) of trails to link Dallas and Fort Worth,
as well as three suburbs between the two cities. It’s part of the
Regional Veloweb program, 1,728 miles ( 2,781 kilometers) of off-street paths intended for cyclists, pedestrians and other nonmotor-ized transportation.
“The Regional Veloweb connects communities to housing, employment and entertainment in the region,” says Kevin Kokes, senior trans-
The National Museum of the
U.S. Air Force (USAF) has begun restoring a rocket that’s
taller than its building.
The museum, in Dayton,
Ohio, USA, will restore and
display a 200-foot-tall Titan
4B rocket vehicle. The restoration project, the largest
the museum has undertaken,
involves finding experts
familiar with Titan 4B, cata-loguing the rocket’s parts in
an airport hangar, moving
them to the museum and
then reassembling them.
“One of the biggest challenges for our staff is going
to be figuring out how to assemble and display [the Titan
4B] horizontally because it
is too tall to stand up inside
the gallery,” Greg Hassler, a
supervisor in the restoration
division, told the Dayton Business Journal.
In conjunction with the
restoration, the museum is
adding a US$35.4 million
building that will house a
new space gallery to open
The Titan 4B was used
from 1997 to 2005 to launch
satellites, as well as the
that is still studying Saturn.
The museum undertook
the restoration project to
showcase the Air Force’s role
in space missions. “The Titan
4B and the exhibit space
around it will be crucial for
telling the USAF space story,”
Doug Lantry, PhD, project
manager for the new space
gallery, told the Dayton Business Journal. —Imani Mixon
