The structure is located in the K0 + 194.93 between the municipalities of Garzón and El Agrado (Huila). The bridge, more than 1,7 km long and 8.50 m wide, is considered to be the longest one in Colombia.
The access area to the bridge consists of three span slabs on a beam, approximately 24.50 m long, supported on an initial abutment, intermediate pier-pile frames type supports, and a final support which consists of pier cap, block and deep foundation, which also serves as a support of the initial span of the bridge built using the progressive cantilever method.
The total width of the deck is 8.50 m, consisting of two lanes of 3.67 m, a sidewalk of 0.80 m and a New Jersey type barrier 0.35 m wide.
At the remaining spans, a box girder with variable depth (7.40 to 1.81 m) and length (5.00 to 3.50 m) is designed in segments up to complete 130 m between axis or intermediate piers, the same system is repeated until crossing the entire river, and connecting the viaduct of 940 m which is designed with a slab over beams with 20 m length spans.
For pier foundation it is designed the use of 4 piles 2 m diameter, and 18 m deep.
This structure has been built using the progressive cantilever method starting symmetrically from the intermediate piers towards their ends (abutments or centers of spans).
