Construction

Interstate 80 was constructed in segments, starting in the 1950s. By the late 1970s the Utah portion of I-80 was largely complete, except for a gap on the western edge of Salt Lake City. A 5 miles (8 km) section between Redwood Road and the Salt Lake International Airport holds the distinction of being the final link of Interstate 80 to be completed. This section was dedicated on August 22nd, 1986. This coincidentally was close to the 30th birthday of the Interstate Highway System

Reconstruction

Reconstruction of I-80 began in August 2007, from State Street (US-89) east to 1300 East (former SR-181). Dubbed "Innovate 80," phase one of the project involved temporarily widening bridges on the eastbound side of the freeway to accommodate five lanes (three lanes in one direction and two in the other). The center lane was made reversible so there would be three westbound lanes during the morning commute and three eastbound lanes during the evening commute. Phase two began December of that same year, reconstructing the westbound lanes and replacing the bridges. The bridges were all constructed in advance and then moved to their respective positions, beginning with the Highland Drive bridge, the 900 East bridge, the 700 East bridge, the 600 East bridge, the 500 East bridge, the 300 East bridge, and the 700 East ramp, which extends over 600 East. The westbound bridge moves were completed July 31.

Phase three began in October 2008, involving the eastbound lanes and bridges being reconstructed from 700 East to 1300 East (traffic traveled on the new pavement on the north side of the freeway). However, the bridges on the eastbound lanes were replaced with the traditional manner, constructing them on the spot of where they would lay. With the project's completion in November 2009, there are now five lanes in each direction (one of those being an auxiliary lane in between exits) compared to three lanes prior to 2007. As part of the project, sound walls were added, grade-level signage was replaced with overhead signs, on- and off-ramps were lengthened, and the State Street bridge received a bridge deck replacement, as opposed to a new bridge.
