The Taylor–Southgate Bridge is a continuous truss bridge that was built in 1995. It has a main span of 850 feet (260 m), and a total span of 1,850 feet (560 m). The bridge carries U.S. Route 27 across the Ohio River, connecting Newport, Kentucky and Cincinnati, Ohio.
The arches are semicircular, and their thickness T depends both on the span a of the arches and on the height H of the structure: [7] If H = 2.5 a, T = 0.1 a + 0.04H If H < 2.5 a, T = 0.125 a + 0.04H However, if the span a is small (a<8 m), it is preferable to use the following formula for T: T = 0.15 a + 0.4.

The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

This exception allows for the standard 5-axle semi-truck configuration to gross up to 80,000 pounds (36,000 kg) (the legal limit) [9] without being in violation of the bridge formula law. Without it, the bridge formula would allow an actual weight of only 66,000 pounds (30,000 kg) to 67,500 pounds (30,600 kg) on tandems spaced 36 feet (11 m) to ...
ASHEVILLE — Two concrete segments jutting out over Interstate 26 will soon be 3 feet apart — and connected later this spring — into a new Blue Ridge Parkway bridge, according to a Feb. 14 ...
A double-T beam or double tee beam is a load-bearing structure that resemble two T-beams connected to each other. Double tees are manufactured from prestressed concrete using pretensioning beds of about 200-foot (61 m) to 500-foot (150 m) long. The strong bond of the flange (horizontal section) and the two webs (vertical members) creates a ...

The profile T pr has the same lower frame requirement but reduces the maximum upper body width to 3,500 mm (11 ft 5 + 13 ⁄ 16 in). The more universal profile 1-T has the complete body at a maximum width of 3,400 mm (11 ft 1 + 7 ⁄ 8 in) still rising to a height of 5,300 mm (17 ft 4 + 11 ⁄ 16 in). [55]
