Porter Rockwell Bridge

Construction of a 2-span steel bridge across Jordan River Narrows in Bluffdale UT. Multiple phases of access roads needed to be constructed for efficient constructability for the bridge structure.

2 Box Culverts needed to be constructed to enable access for the bridge foundation to begin. (4) 96” drilled shafts in the Jordan River were installed in the off-water season to accomplish this work. Culverts were single barrel with lengths of 159’ and 459’ respectively.

Other project improvements involved casing a 48” welded steel waterline in a 60-inch casing to protect the existing line in the new roadway profile. This was also done in the off-season of water works.

1400 ft of HMA mainline paving and a 1500’ paving of the Jordan River Parkway trail for pedestrian and equestrian use.

Equipment for this was unique for the limited access and accommodation of bridge erection. There was a multitude of cranes used in this operation. Manitowoc 12000, 14000, Kobelco 300 Ton cranes to install phase two.

This project was cut off in the middle, making the project team treat it like two separate projects. This was a unique project with the parameters that were given, Railroad coordination was a critical collaboration point as well. Temporary bridges were used for access across canals into work areas.
