The southbound I-405 connector to the eastbound SR-22 freeway has been reconstructed in order to make room for the new carpool connector. Once construction on the new connector is complete, the old connector must be demolished. In order to demolish the old structure, portions of the eastbound SR-22, northbound I-405 and southbound I-405 freeways will be closed for approximately 20 hours, the weekend of August 17 to 18.
