OCTA is starting a 405 freeway widening project that will run from Costa Mesa to the 605 in Seal Beach. Some of the bridges we use to cross the 405 (e.g. Ward, Talbert) are set to be rebuilt and may be closed entirely during construction. Please email roads@bikeirvine.org if you notice any closures. Your humble ride coordinator lives in South OC, so I may not be aware of when these closures start and their impact on our routes.
