The Big I - Albuquerque, N.M.
The $237 million contract was the largest capital works project awarded in New Mexico and involved reconstruction and expansion of nearly 2 miles of the existing Interstate 25 and Interstate 40 interchange through central Albuquerque. Features of the reconfiguration included increased auxiliary merge distances; smoother, straighter roadways leading to improved performance; addition of interior and exterior shoulders; and fewer motorist weaves or lane changes due to elimination of left-hand on/off ramps.
Fifty-five bridges were built as part of the project including 33 concrete girder bridges, four structural steel girder bridges, 10 rehabilitated bridges and eight new precast segmental fly-over bridges, which have become the trademark of the project because of their magnificent arcs. At 80 feet tall and more than 2,800 feet long, the I-25 southbound to the I-40 eastbound bridge includes 206 individual segments and is the longest bridge in the state of New Mexico.
Major items of work included 4 miles of soundwall; 111 lane-miles of paving; 16 miles of bridge beams; 154 miles of conduit; 29 miles of concrete barrier wall; 4 miles of drilled shafts; 7.5 million pounds of rebar; 5 million pounds of structural steel; and 70 miles of utility work.
