I-5 Improvement project

Every day, more than 350,000 motorists drive this segment of I-5 between I-405 and SR-55, to connect with major residential, commercial, educational and employment destinations. Already at capacity, traffic projections show that nearly 500,000 motorists will travel this stretch of I-5 by 2040. The project will reduce both existing and future mainline congestion on I-5 from I-405 in Irvine to SR-55 in Tustin, as well as improving interchange traffic operations on local streets by adding an additional freeway lane in each direction as well as implementing selected improvements to adjacent interchanges.
