In the US state of Texas, work is in hand to build new bridges carrying US-281 over the Colorado River at Marble Falls.

The 3499 Texas Department of Transportation has set a budget of close to US$30 million to replace the existing Lake Marble Falls Bridge with two new bridges. This crossing is some 80km from Austin and the project requires the demolition of the existing steel truss bridge and the construction of twin segmental bridges. The new bridges will be built using the balanced cantilever construction method with end spans constructed on falsework.

Finley Engineering Group (FINLEY) carried out a time-dependent staged analysis of the structure to monitor stresses and expected deflection during construction. The firm revised the segment layout and optimised the post-tensioning layout, which reduced costs and construction time. The analysis process included developing a model, which used Bridge Information Modeling (BrIM). This allowed the synchronisation of the CADD shop drawings with the analysis model, to meet the contractor’s fast-pace construction schedule. The first of the new bridges is under construction at present and is due for completion in mid 2012. The second bridge will be finished in 2014. Archer-Western Contractors is building the two structures and FINLEY’s portion of the project includes bridge design and a full construction engineering package.

    Contractor Ringway has completed work on a tricky project to replace Stile Farm Bridge, which crosses the Great Stour River near Chilham in County Kent, south-east England. Built in the 1920s, the bridge was in a severe state of disrepair resulting in weight restrictions of just 3tonnes. The new structure has a 16m span and is constructed using pre-cast concrete, with pre-stressed steel-reinforced beams based on cast in-situ abutment, and enables the bridge to carry heavier traffic. As well as helping to ea

This will give the Greater Vienna region its first-ever high-capacity link to the Czech motorway and arterial road network, greatly easing congestion on the old main road. In the first phase of construction, 22.7km of motorway are to be built. Work on the second section, all the way through to the Czech border, is to start in 2010. The A5 Norda
