I-80 Two Bridges Echo

Michael Baker Jr., Inc. teamed with Ralph L Wadsworth Construction Company, LLC. on the $3.1M design-build project near Echo, Utah.

The project included the design and construction of two single-span bridges on I-80 over Echo Dam Road, bridge approaches and roadway improvements for safety and drainage. The bridges were constructed using accelerated bridge construction (ABC) methods. The schedule for this project was very aggressive. The bridges were designed and constructed in 135 days from the notice to proceed. Each bridge and its approach slabs were constructed adjacent to the existing bridge on temporary abutments. At the same time, new abutments were constructed beneath the existing bridges. Each bridge was demolished and the new structures were slid into final position on new abutments; each during a single seven-hour night-time closure of I-80.
