U.S. 190 – Amite River Bridge Project
Oct. 28, 2010
The contractor continues driving piles for the new eastbound span. Thus far, 259 of the 272 production piles have been driven.
The contractor continues pouring bridge caps. A cap is the part of the bridge that sits on top of a group of piles and will help disperse pressure to the piles below. Thus far, 58 of the 60 bent caps have been poured.
The contractor also continues to pour the bridge’s deck. Thus far, 18 of the 20 bridge deck spans have been poured. The deck is the road surface of the bridge. It rests on the girders which are supported by bents. Bents are made up of caps and piles.
In addition, work continues on building the new eastbound roadway.
Brief description of completed work:
The contractor has completed building the haul road on the west side of the river. The haul road was used by the contractor to bring equipment and building material to and from the job site while working on the new westbound span.
All four of the test piles have been driven. Test piles help to gather information on the conditions at the job site such as installation methods for future piles and soil type. The information determines proper pile lengths and driving criteria for the production piles for the new bridge.
The contractor completed the westbound roadway and bridge. Traffic was moved to the new bridge on Sept. 11, 2009.
The old westbound bridge was demolished on Oct. 21, 2009.
