2014-2015 Bridge
Design Summary
-
The Pratt under truss design was for its symmetry and repetition as well as its ability to accommodate simple connection details
-
Structure dimensions were chosen so that the size of each component could be maximized while keeping the bridge compact as a whole
Acceleration Bridge Construction
-
Repetition of bridge components fabricated using jigs to avoid problems with tolerances
-
Use of lightweight hollow steel sections (HSS)
-
Splice plate connections are used throughout the entire structure for faster construction
Current Construction Sequence
-
Four legs are placed and the first two truss components are connected to each leg
-
Lateral bracing is attached connecting the two legs on either end of the bridge
-
Repeating truss components are built to midspan with lateral braces connecting to parallel trusses simultaneously
-
Center truss components are installed at midspan to connect the two halves of the bridge together
