DIA Peña Boulevard Widening

This project consisted of an approximately three-mile section of Peña Boulevard, which is a four-lane, limited access freeway including diamond interchanges, entry and exit access control plazas, frontage and service roads, storm drainage systems, and six bridge structures. The facility was designed to have an ultimate capacity of five lanes in each direction capable of handling projected 55,000,000 annual enplanements. Geometric design and location alternatives were developed for the $24 million roadway project to maximize the amount of developable land adjacent to the airport and minimize the “footprint” of the access control plaza. The access control plazas, encompassing 29 travel lanes, in conjunction with automated vehicle identification lanes, provide the most cost-effective and efficient design alternative. Detailed traffic analyses were performed using state of the art computer software to determine access plaza capacity, optimal queuing, timing, and probable delay. In addition to traffic studies at the plaza areas, traffic analyses were performed at interchanges, acceleration and deceleration lanes, and selected freeway segments. Included in the design are signalization, signing and striping plans. The 185-foot, post-tensioned, cast-in-place bridge structures were designed to easily accommodate future expansion. In addition to the project's preliminary and final design, the work will include construction observation and administration.
