A new road bridge is now open in US capital Washington DC, improving capacity and safety in the city.

The new structure spans New York Avenue and provides the busy Ninth Street link into the city. Carrying up to 25,000 vehicles/day, including some 2,000 trucks/day, the bridge is a major transport connection into the Northeastern side of the city. The roadway for the new bridge is 15.8m wide, boosting capacity over the 34.4m wide structure it replaces. The pedestrian walkways are also wider than on the old bridge. The new bridge also features a centreline barrier that meets safety requirements and prevents the risk of cross-over collisions. This structure is made from high performance concrete and corrosion resistant steel has a design life of 75 years and replaces an aging bridge that was first opened to traffic in 1941 and which had proven unable to meet the traffic demands imposed upon it.

    Transport infrastructure is taken for granted in many, if not most, developed countries. This has resulted in a shortage of investment in maintenance, posing potential long term cost issues. In many developing nations transport networks are expanding fast, but insufficient thought is also being given to how these will be maintained.

    The 5700C-Max unit from Power Curbers has now been used on a tricky shoulder widening job in New South Wales, Australia. The machine carried out the job close to Robertson in the Southern Highlands, about 1.5 hours drive to the south of Sydney. The job required the construction of a 200m long section of barrier, built to the requirements of the Roads and Traffic Authority (RTA). The contractor hand-formed the concrete shoulder as it was about 3m wide at the start and narrowed down to 1m at the end.

    Imaginative formwork, often using modular components, is helping to shape some challenging bridges worldwide. Patrick Smith reports Traffic volumes in and around Prague have swollen massively in recent years, pushing the existing road network to the limits of its capacity. To permanently ease congestion in the Czech capital's centre, a multi-lane orbital motorway is under construction as a high capacity bypass for central Prague and to link up all the motorways and other major highways radiating from the ci
