It put the north end of the main span well off the edge of the roadway on a canal bank.
This truss is a structure of connected elements forming triangular units. To the left is Minnesota Governor Tim Pawlenty.
The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by nineteenth and early twentieth century engineers. Early morning view of the main span of the FIU-Sweetwater UniversityCity Pedestrian Bridge as it was lifted from its temporary supports, rotated 90 degrees across an eight-lane thoroughfare and lowered into its permanent By The cracks were discussed at a meeting of project team members the morning of the collapse, though no safety concerns were raised, FDOT said.
