A method of manufacture for an elongated, curved roller coaster track (512, 600, 700), comprising the steps of: designing the elongated, curved roller coaster track having a cross-section profile that comprises both an I-beam and a substantially rectangular portion and extending in three dimensions wherein a design of a curve of the roller coaster track comprises a first vertical member (601, 701), a second vertical member (602, 702), a top horizontal member (603, 703) adapted to engage the wheels of a roller coaster car, a horizontal bottom member (604, 704), a first vertical inside member (605, 705) and a horizontal second inside member (606, 706), the top member being coupled to the first member, the second member and the first inside member, the bottom member being coupled to the first member and the second member, and the second inside member being coupled to the first inside member and the second member, whereby the first member and the second member form the vertical part of the I-beam cross-section profile, the bottom member and the top member form the horizontal part of the I-beam cross-section profile and the top member, the second member and the first and the second inside members form the substantially rectangular portion cross-section profile; mapping out the first member, the second member, the top member, the bottom member, the first inside member and the second inside member on two-dimensional planar material; cutting out the first member, the second member, the top member, the bottom member, the first inside member and the second inside member from the two-dimensional planar material; and coupling the cut-out first member, the second member, the top member, the bottom member, the first inside member and the second inside member substantially without manufacturing bending stress to form the elongated, curved roller coaster track. designing the elongated, curved roller coaster track having a cross-section profile that comprises both an I-beam and a substantially rectangular portion and extending in three dimensions wherein a design of a curve of the roller coaster track comprises a first vertical member (601, 701), a second vertical member (602, 702), a top horizontal member (603, 703) adapted to engage the wheels of a roller coaster car, a horizontal bottom member (604, 704), a first vertical inside member (605, 705) and a horizontal second inside member (606, 706), the top member being coupled to the first member, the second member and the first inside member, the bottom member being coupled to the first member and the second member, and the second inside member being coupled to the first inside member and the second member, whereby the first member and the second member form the vertical part of the I-beam cross-section profile, the bottom member and the top member form the horizontal part of the I-beam cross-section profile and the top member, the second member and the first and the second inside members form the substantially rectangular portion cross-section profile; mapping out the first member, the second member, the top member, the bottom member, the first inside member and the second inside member on two-dimensional planar material; cutting out the first member, the second member, the top member, the bottom member, the first inside member and the second inside member from the two-dimensional planar material; and coupling the cut-out first member, the second member, the top member, the bottom member, the first inside member and the second inside member substantially without manufacturing bending stress to form the elongated, curved roller coaster track.
