This final package will construct three connectors, one from eastbound I-80 to southbound I-680, one from northbound I-680 to westbound I-80, and one from westbound SR 12 to southbound I-680. The first two connectors will be low-volume ramps that complete the I-80/I-680 interchange component of this project. Constructing the northbound I-680 to westbound I-80 connector will require replacement of the Union Pacific Railroad (UPRR) Cordelia Underpass, including new track.
