The bridge cost $14 million (equivalent to $21.6 million in 2023 [1]) and was part of an approximately $520 million (equivalent to $804 million in 2023 [1]) I-94 improvements. The unique design meant that the cost was $2 million (equivalent to $3.1 million in 2023 [ 1 ] ) higher than conventional plate-girder bridges, causing public controversy.
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
It cost $200,000 to set up a temporary traffic control system and $200,000 more to temporarily divert the creek. The project allocated $197,772 for steel reinforcing bars, $192,215 for erosion ...
The base of the bridge will also be raised to 230 ft., which is a 45-foot increase to accommodate ship traffic. The roadway will still be two lanes wide going in each direction.
Falsework includes temporary support structures for formwork used to mold concrete [1] in the construction of buildings, bridges, and elevated roadways. The British Standards of practice for falsework, BS 5975:2008, defines falsework as "Any temporary structure used to support a permanent structure while it is not self-supporting."
In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape ...
While the total cost was expected to be between USD $300 million and $350 million for the 1,900-foot (579 m) multi-span bridge, including financial incentives for accelerating the schedule, [11] the winning bid was for USD $234 million. Disincentives for missing the completion date of December 24, 2008 included a $200,000 per day penalty, while ...
