136th Avenue Bridge over I-25

136h Avenue bridge

Completed in July 2004, the 136th Avenue Bridge over I-25 was a joint project between the cities of Westminster and Thornton, and it was funded by both cities without state or federal funds. The names of the two cities are located on the east (Thornton) and west (Westminster) sides of the bridge.

The design features decorative arched metal railings on the bridge deck with stone-clad pilasters topped with lighted orbs. The bridge is accentuated by a series of stone retaining walls and landscaping. The bridge was designed to protect and preserve a grove of huge cottonwood trees at the northwest quadrant of the intersection. Uplighting illuminates the trees and the bridge at night. The bridge design is the same as the 144th Avenue Bridge over I-25.

The bridge designer was Felsburg, Holt and Ullevig and the landscape architect was Frank Miltenberger. The bridge won the “Gold Hard Hat Award” from McGraw Hill Construction in October 2004 and the “Merit Award” from the American Council of Engineering Companies in November 2004.
