The Colorado Dept. of Transportation completed a complex bridge replacement on July 21 after crews rolled the new 2,400-ton Pecos Street Bridge over I-70 into place over one weekend. The highly coordinated bridge move allowed CCDOT to reopen I-70 through central Denver 4.5 hours ahead of schedule.
The 4.8-million-lb bridge started moving onto I-70 at noon on Saturday, the 20th, and was placed in its final configuration around 1 a.m. Sunday morning. The project also added a new pedestrian bridge over the freeway on the west side of Pecos Street. “Our decision to completely close I-70 for one full weekend reduced what could have been an additional eight months of lane closures,” said CDOT Project Engineer Tamara Hunter-Maurer.
