Crews from Swank Construction will conduct repair work to bridges on I-579. The long-term repair work follows previous inspection activities where the department found significant deterioration on several piers on I-579 and the I-579 HOV lanes. Out of an abundance of caution, traffic was shifted on mainline I-579 and completely removed from the I-579 HOV lanes while analysis was conducted. The department performed hands-on inspections of 35 piers in this location. The project team has been in constant communication to safely and efficiently develop and implement repairs while minimizing the impacts to motorists. The repair plan makes necessary long-term repairs while maintaining as much traffic flow as possible.
