cunningham Highway–cunningham’s gap restoration
In early 2011, cyclones and heavy flooding devastated the state of Queensland,
Australia. recovery from millions of dollars in property and infrastructure
damage will require restoration of rail works and reconstruction of
approximately 300 roads and highways. A vital transport link, the severely
damaged cunningham’s Gap section of cunningham Highway is being rebuilt at
a cost of $40 million.
In the preliminary phase, Queensland Department of Transport and main
roads stabilized the steep and densely vegetated project site. Survey data
was provided by terrestrial laser scanning, ground survey, and aerial scanning.
Smec Australia used microStation and mXroAD to process the point cloud
data. microStation imported, integrated, and transferred data into a digital
terrain model, which was used to assess the road conditions and complete

Four laning of rohtak-panipat (nH71A)
The four laning of national Highway 71A from rohtak to panipat will improve
capacity and reduce travel time from western to northern India by allowing
travelers to bypass Delhi. The $148 million project includes six bypasses,
11 major and minor bridges, five fly-overs, and two trumpet interchanges
connecting national Highway 71A to national Highway 10 at one end and
national Highway 1 at the other end of the 80-kilometer section.
STUp consultants assisted in detailed engineering design and preparation of
working drawings. The major challenge was retaining the existing two-lane
road and designing a new two-lane roadway alongside. S TUp used mXroAD
to design the horizontal alignment and vertical profile, and generate plan
profile drawings and detailed cross sections. overlay design of the existing
carriageway generated accurate quantities in less time.
