The Christopher S. Bond Bridge will inch further to completion this morning when road crews install the 40th and final cable to the new Missouri River crossing.
The installation of the cable, measuring 540-feet long, will provide the support needed for road crews to build the last 38 feet of the bridge to the south side of the Missouri River.
With all the cables in place, the new cable-stayed bridge will have a harp-like appearance.
It’s called a cable-stayed bridge because the cables are in a "stayed" or fixed position, attached to the pylon so the bridge’s weight is supported by the tower.
It’s different from the existing Paseo Bridge, a suspension bridge with cables strung freely across the towers and anchored at both ends where the bridge is supported.
The new Bond Bridge is part of a $245 million project that also calls for widening I-29/35 to three lanes in each direction from downtown to north of Missouri 210/Armour Road. The entire project is expected to be done by June 2011.
The highway work will bring a new closure this morning when the ramp from 16th Avenue to southbound I-29/35 will close after rush hour today until December.
