Technology transportation trends Constructech Share    
Here are a few things to keep an eye out for with regards to transportation construction in the year ahead: managing in lean times, bans or restrictions on cellphone use while driving, increasing visibility of transportation with upcoming presidential campaign, new ways to fund transportation, advances in intercity passenger rail and new stormwater reforms and other environmental regulations. More Pueblo, Colo.'s 4th Street Bridge recognized for environmental excellence Rebuilding America's Infrastructure Share
The new 4th Street Bridge, which crosses over 28 active railroad tracks, the Arkansas River, a pedestrian and bike path, and city street, was constructed adjacent to the 1958 structure it replaced. The construction team used a cast-in-place cantilever method, wetland pad, river barrier, bridge removal decking over the river, onsite dewatering and other innovative methods to avoid or minimize impacts to the surrounding environment, including wetlands, water quality, historic resources and migratory birds.

This year's conference will be held at Seven Springs Mountain Resort in Champion, Pa. We are now making exhibit spaces available to our members and friends. Click on the logo for more information! Forward momentum for 2012 Better Roads Share
Momentum is sometimes hard to define. In sports, it may be a crucial play that changes the outcome of the game. In business, however, it might be something as simple as a sale that leads to an unexpected customer base. Often, it may seem like a small pebble, but once it starts rolling downhill — gaining mass and velocity along the way — its impact can be significant. More Accelerated bridge construction: Bent on safety Roads&Bridges Share
Worsening traffic congestion and public impatience with delays have made accelerated bridge construction a necessity. Particularly in urban environments, closing traffic lanes for extended periods to construct a bridge is no longer acceptable. Therefore, owners, engineers and planners need to find ways of constructing bridges that shorten the time needed on-site. More Equipment executive: The times...they are a changin' Construction Equipment Magazine Share
It's scary how many significant changes are happening simultaneously. Sure, most of the changes are good and add productivity, but how do we keep up? Consider the effect of the following changes, in no specific order, that have accelerated in the past 10 years. More Battle to save historic truss bridge likely to end in compromise Smoky Mountain News Share
A compromise has emerged in a fight over the historic McCoy truss bridge in North Carolina, one that would keep the old bridge in place for foot traffic while building a newer, bigger bridge alongside it for vehicles. But Macon residents who have spent nearly 10 years fighting for the bridge still feel ignored. More Construction employment below peak levels nationwide as funding for highways begins The Associated General Contractors of America Share
Five years after states first started shedding construction jobs, construction employment remains below peak levels in all fifty states and the District of Columbia according to a new analysis released today by the Associated General Contractors of America. Given the continued weakness in construction employment, the association is launching a new effort to encourage Congress to pass years-late legislation to fund highway, bridge and transit construction work. More Long-term performance of polymer concrete for bridge decks Transportation Research Board Share
TRB's National Cooperative Highway Research Program Synthesis 423: Long-Term Performance of Polymer Concrete for Bridge Decks addresses a number of topics related to thin polymer overlays. Those topics include previous research, specifications, and procedures on TPOs; performance of TPOs based on field applications; the primary factors that influence TPO performance; current construction guidelines for TPOs related to surface preparation, mixing and placement, consolidation, and more.
