Traffic on the northbound 405 freeway flowed well on Saturday night, sometimes in the “free flow” condition — i.e. with traffic moving at normal speeds. The above Google map shows traffic as of 11 p.m.

The northbound lanes will be entirely closed from 2 a.m. until 7 a.m. Sunday — with lane closures beginning at 1 a.m. Only northbound lanes will be open during the day Sunday.

Because of traffic and safety concerns, both connectors from the 10 freeway to the northbound 405 will remain closed for the remainder of Jamzilla closures.

Again, the message remains the same: please avoid driving on the northbound side of the 405 on Sunday and through this holiday weekend. The freeway can only handle about a third of its normal traffic load when only two lanes are open. Click here to see the full schedule of closures this weekend.

Repaving work remains on schedule. The I-405 Sepulveda Pass Improvements Project is providing frequent updates on its Twitter feed. The project is adding a northbound HOV lane to the 405 between the 10 and 101 freeways to match the existing lane on the southbound side of the freeway.
