The lower chord is 360mm in diameter while the two top chords are 280mm in diameter.

The bridge does not balance the forces by using a symmetrical arrangement of cable forces on each side of its support tower instead, it uses a cantilever tower, set at a 42-degree angle and loaded by cable stays on only one side.

The cable for the bridge totals 4,342 feet and was made in England. The bridge was completed in 2004, three years later than originally planned, at a cost of $23.5 million, with funding from the Redding-based McConnell Foundation.

Since I will likely only have to remove one vertical stud in order to create a 30" door frame opening, would removing one stud create undue stress on the load bearing nature of the wall? And, if so, could I alleviate this stress by simply sistering two studs together on both sides of new door frame, then adding a header? Then, I wish to create a 30" door opening in the load bearing wall for a new door to the laundry room. I intend to remove the current access point and create a solid wall in its place. Project: The door to the laundry is currently on an adjacent wall by the back door. ![]() BTW, the window that appears in the pic will be removed. For the sake of argument and my question below, I will say that it is load bearing. ![]() I am fairly certain that this is a load bearing wall, but will determine for sure at a later time. I have an interior wall that separates the kitchen from the laundry room.
