This Interactive Map Will Help You Navigate the I-405 during Construction

OCTA recently launched a fully interactive, mobile-friendly resource for the I-405 Improvement Project.

The largest project in OCTA’s history, the I-405 Improvement Project will improve 16 miles of the I-405 and add one regular lane in each direction from Euclid Street to I-605. It will also construct the 405 Express Lanes from SR-73 to I-605.

On the map, users can click on a location along the project to see when construction is anticipated to start, find details on any current pre-construction activities, and view the planned improvements in the area.

When construction officially starts in early 2018, users can explore the project area in real time, view both planned improvements and current construction activities for each interchange, and receive updated closure and detour information.
