Milton, KY: Time Lapse Video of Milton-Madison Bridge Milestones

This video highlights the construction milestones of the Milton-Madison Bridge, which include the rising of the trusses into place on temporary piers…the blasts that brought down the old bridge…and the amazing slide of the new bridge onto its permanent piers. The half-mile structure was slid 55 feet making this the longest bridge slide of its type in North America — perhaps the world.

Lowell, MI: Sliding the Alden Nash Avenue Bridge Into Place

Lowell, MI: Sliding the Alden Nash Avenue Bridge Into Place

The new bridge will be constructed adjacent to the existing bridge and traffic will be diverted to the new bridge in its temporary location. The old structure was demolished and the new bridge was slid into place. Bridge slide technology greatly reduces the amount of time a bridge is out of service. M-50 was closed and detoured for only two weekends (during demolition and during the slide), as opposed to a multiple-month closure typically associated with a traditional bridge replacement.

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.
