Rapidly improving design technology and the desire to optimise structural designs, present challenges, and also opportunities, for bridge designers. One of the most important components of a modern bridge is the bearings.

Roads and Maritime Services of NSW (RMS) design, accept and manage barriers for use on classified roads and bridges. Crash testing of a system of barrier units is infrequently performed due to high costs and a myriad of impact conditions that needs…

As part of the Northern Beaches Hospital Connectivity and Network Enhancement Project, Warringah Road is being upgraded and widened to accommodate grade separation. The upgrade includes two new shared path bridges, at Forest Way and Hilmer Street,…

The aftermath of the Christchurch earthquake highlighted difficulties in the assessment and repair of damaged plastic hinge zones in conventional reinforced concrete structures. Particular issues are uncertainty in strain history, low-cycle fatigue,…

Four bridges in the Fiji Islands were recently replaced using a Design and Construction procurement method for the Fiji Road Authority. The bridges provided vehicle, pedestrian and Fiji Sugar Corporation cane trains over waterways subjected to…

Increasingly, around the world, a type of bridge is emerging that is designed principally for cyclists. These bridges, which can be termed velobridges, enhance personal mobility, reduce traffic congestion, improve community health and promote social…

The Kookaburra Viaduct connects Jacksons International Airport and the Waigani district, where the Papua New Guinea government offices are located, in Port Moresby. The purpose of the project was to provide an efficient and uninterrupted connection…

Integral and semi-integral bridges are a common form of construction, providing some marked advantages over other construction forms. Integral and semi-integral bridges minimise the use of bearings and expansion joints by providing a direct…

Incrementally launched prestressed concrete bridges are built in segments in the casting bed. Finished segments are pushed out of the casting bed to leave space for construction of subsequent segments. The resulting geometry of the bridge will be…

In recent years the circumferential wrapping with externally-bonded carbon fibre-reinforced polymer (CFRP) composites has proven to be a promising method for strengthening concrete structures. This is particularly valuable when repairing concrete…
