Ipswich Motorway Upgrade
Part of the western corridor into Brisbane, Australia, the Safelink Ipswich
Motorway operates under peak demand with significant commute delays
and poor safety records. This project includes upgrading 2. 5 kilometers of
centenary motorway; expanding 5. 5 kilometers of Ipswich Motorway from
four to six lanes; earthworks and bridgeworks for a new rail line; a new
multilevel interchange for road and rail; and civil works involving 30 bridges,
underpasses, and drainage structures.
With the motorways required to be fully operational during construction,
the design team had to focus on temporary works and staging as well as the
ultimate design. Because a skilled-labor shortage necessitated gathering team
members from around the globe, the project team selected MXROAD and
Project Wise as intuitive design tools with the flexibility to operate on multiple
CAD platforms and manage design data among offices.

Southwest Parkway Interchange
Fort Worth, Texas, United States
Southwest Parkway is a proposed 8.2-mile, six-lane tollway that North Texas
Tollway Authority (N T TA) will build and operate. It will improve regional
mobility by relieving the growing traffic congestion in the greater Fort Worth
area. Extending from Fort Worth’s central business district at IH- 30 to
southwest Fort Worth, Southwest Park way eventually connects to the 13-mile
Chisholm Trail project in Johnson County.
As part of the project, HDR designed a new five-level interchange at SH-183 and
IH- 20. HDR’s segment consists of two miles of new roadway, six-lane mainlines
on Southwest Park way with localized frontage roads, more than one mile of
SH-183 reconstruction with new frontage roads, and direct connectors to IH- 20.
The project includes nine direct connectors, 15 slip ramps, and reconstruction of
one cross-street underpass.
