History on Route 84, Isabel Avenue and I-580 Isabel Avenue corridor planned as future Highway 84 since 1950’s Route 84/I-580 Interchange envisioned in City-State Freeway Agreement in 1960’s Isabel Avenue Extension project completed in 2000 State Route 84 transferred to Isabel Avenue corridor in 2003 Isabel Avenue/I-580 Interchange currently under construction
Isabel Avenue/I-580 Interchange: The Isabel/580 interchange will provide the permanent connection between I-580 and Isabel Avenue/State Route 84 to relieve congestion at the existing Airway/I-580 interchange and enhance traffic circulation within the business and commercial area north of 580. The Isabel/I-580 interchange will improve access to the residential developments, commercial businesses, Las Positas College, and future development north of I-580 by creating two additional crossings over I-580. As part of this project, the partial-access Portola interchange will be removed and replaced with a flyover extension of Portola Avenue that will connect to Isabel Avenue and Portola Avenue north of the freeway. The project has been segmented into three construction contracts with two contracts being administered by the City and the third contract being administered by Caltrans. Construction work has started on all three contracts.  Construction is anticipated to be completed by early 2013. During construction the City will be providing construction updates through the City’s website and by articles in the citywide newsletter. Due to the construction work, traffic delays along Kitty Hawk Road and Airway Boulevard will be necessary to complete the connection of Isabel Avenue to I-580. This project is funded with $68 million Proposition 1B transportation funds, approved by the voters in 2006, $26 million in Alameda County Measure B sales tax funds, $11 million in federal funds, $10 million Tri-Valley Transportation Council funds, and other local development contributions and City funds. For further information on this project, please contact Mike Irby, Project Manager, at (925) 960-4539 or by e-mail at mcirby@ci.livermore.ca.us . [top]
Traffic During Construction  During construction the City will provide updates via this website and in the citywide newsletter. Traffic delays along Kitty Hawk Road and Airway Boulevard will be necessary to complete the connection of Isabel Avenue to I-580. Drivers are encouraged to plan their routes in advance and allow extra time to reach their destination. The City of Livermore would like to thank people for their patience during construction of the Isabel Interchange Project. Please drive with care and give construction crews room to work safely.
