Warwick, Rhode Island: Barton Corner Bridge Replacement

Warwick, Rhode Island: Barton Corner Bridge Replacement

In August 2014 we completed replacement of the Barton Corner Bridge, which carries four lanes of I-95 plus two auxiliary lanes at a busy interchange with Route 2 on the Warwick/West Warwick line. Using accelerated bridge construction, we built two halves of the bridge on land adjacent to the overpass, and then moved them into place. This enabled us to build the bridge much faster compared with conventional construction methods, which would have taken twice the time. This approach also allowed us to do the work with no impact to Interstate traffic prior to installation.

Pennsylvania: Replacing 558 Bridges in 4 Years

Map of Final Bridges - P3 RBR Bridges

PENNSYLVANIA DEPARTMENT OF TRANSPORTATION
With the P3 approach, we can replace hundreds of these bridges more quickly, save money and minimize the impact on the traveling public. SD bridges are not unsafe but pose a serious problem that jeopardizes our ability to grow economically and create jobs. This initiative, in conjunction with Pennsylvania’s new comprehensive transportation funding law that Corbett signed on Nov. 25, 2013, will bring much needed investment to the state’s bridges.

Building A Quake-Proof Bridge

Building A Quake-Proof Bridge

A new, rocking, pre-tensioned concrete bridge support system has been developed by the University of Washington that reduces on-site construction time and minimizes earthquake damage. The 52-ton, 70-foot-long concrete bridge, built atop three 14- by 14-foot, 50-ton-capacity hydraulically driven shake tables at the University of Nevada, Reno, was shaken in a series of simulated earthquakes, culminating in the large ground motions recorded in the deadly and damaging 1995 magnitude 6.9 earthquake in Kobe, Japan.

Lowell, MI: Demolition of the M-50 Bridge

Normally, bridge demolition is a fairly fast process that can even allow for traffic to cross one side of the bridge during work. With the M-50 bridge, the situation was much different. Crews had to close the entire bridge due to the way it was built.
