Description: B-4188 - MARTIN COUNTY Location: Bridge #36 on SR 1523 over Smithwick Creek
Item(s) of Interest
A 2005 IBRD bridge project, which is a trial of an accelerated construction technique used in other states.
90' single span, with 36" steel girders and a full-depth precast deck.
Deck consists of 11 full width, 8' long full depth panels that are longitudinally post-tensioned together.
Panels have four longitudinal post-tensioning ducts, with 5 strands per duct.
Deck panels are attached to the girder by field welding studs to the top of the girder through a recess in the panel and grouting the girder and panel together.
Observations and Points of Discussion:
This site was not visited because there was a delay in delivering the precast concrete deck panels.
However, there was some discussion on the construction progress and provisions for research, evaluation and documentation of the project.
There were no IBRD research funds for this project, but the Structure Design Unit will coordinate documentation of the project activities.
ACTION ITEM(S):
Structure Design will facilitate the project documentation.
