Interstate 80 1300 East to State Street Submitted by Horrocks Engineers The CM/GC team utilized accelerated bridge construction to speed up the schedule for the Interstate 80 project. ABC was used to replace seven bridges along the I-80 corridor in a two-month period from late June through early August 2008. The Horrocks team designed the ABC bridges carrying traffic westbound I-80 at 300 East, 500 East, 600 East, 600 East ramp, 700 East, 900 East and Highland Drive. The technology reduced road closures along mainline I-80 and inconvenience to commuters.
The bridges were constructed in a “bridge farm” located in the infield of the 1300 East interchange loop ramp. A series of carrier beams were designed to pick up the completed bridges and transport them to their final locations. Each bridge was moved by self-propelled modular transports, with the final bridge transported approximately two miles from the bridge farm to the cross street, where abutments were already in place.
