The Roe Highway Extension (Roe 8) project in Western Australia (WA) will undergo a new environmental approval process. This follows a ruling by the WA Supreme Court that previous approvals for the project were invalid. Roe 8's approval was disputed in the court by the Save Beeliar Wetlands Group that argued the Environmental Protection Authority (EPA) did not apply policies on land offsets when evaluating the project. The WA state government said that Roe 8 is an important part of the US$1.1 billion (A$1.6

The Indian Government has announced plans for major road projects in Bihar, Jharkhand and Tamil Nadu. A 222km road upgrade project will expand the National Highway 2 in Bihar and Jharkhand. The work is expected to cost around US$725.5 million and involves widening the route to six lanes, with three in either direction. The stretch of the NH – 2 planned for this upgrade will run from the Aurangabad Bihar/Jharkhand Border - Barwa Adda. Nine roads in the state of Tamil Nadu will be upgraded, with the work expe

In the UK the Lanes Group is carrying out the contract to build specialist drainage for the New Wear Bridge in Sunderland. The Lanes Group will carry out this work for the joint venture partners building the new bridge link.

Winter was coming in the northern US state of Illinois and Sangamo Construction had to build 1.5km of bridge parapets just before the end of the construction season. Sangamo Construction was contracted to work on five bridges where some parapets needed to be 1m high x 48cm thick at the bottom, tapering to a width of just under 27cm at the top, and with a perpendicular rear wall. As much as 26m3 of concrete were processed just for the construction of the four 150m-long parapets on the twin bridges on Interst

Bridges in seven European countries are part of a three-and-a-half-year programme to develop an inexpensive and low-power wireless structural health monitoring technique. Project SENSKIN, launched last summer in Athens, will run until December 2018. It is focussed on applying a skin-like sensor that offers spatial sensing of irregular surfaces, especially transportation bridges. Up to now, structural health monitoring has relied on a point-based system that requires a dense network of sensors over the bridg

Warsaw’s General Stefan Rowecki Bridge, or the Grota Bridge, is the second largest in the Polish capital and, as part of the Trasa Toruska expressway, it is the busiest. The structure, which opened in 1981, handles 150,000 cars daily, so repairs were always going to be tricky if minimal disruption to traffic was to occur. The steel orthotropic deck consists of two structurally independent parts – each with four traffic lanes. This meant that pedestrians and cyclists were restricted to two very narrow track

Plans are being drawn up for a major programme of road paving work in Brazil’s mato Grosso State. The plans are being made the by the state authorities and involve paving around 10,000km of roads by 2018. The work is expected to cost in the region of US$2.48 billion. Because of the scale of the work, this exceeds state funds. Some 530km of roads in the state were paved in 2015, with a plan to pave 930km in 2016. The financing sources for the paving works have yet to be finalised. In addition a number of o
