Project Update: I-5 Improvements Between SR-170 and SR-118 are Nearing Completion

We’re so close to finishing! The new I-5 carpool lane project between SR-118 and SR-170 is almost done! The contractor is on track to complete both the carpool lane and the carpool lane connector between I-5 and SR-170 in April 2015. (The carpool lane connector will allow carpoolers to travel directly from one freeway to another without leaving the carpool lane.)

And here’s a bonus! The carpool lanes south of this project, between SR-170 and Buena Vista Street, will open at the same time, creating a new continuous eight-mile stretch of carpool lanes. These improvements will:

       > Enhance safety
       > Improve traffic flow
       > Relieve congestion
       > Encourage ride-sharing
       > Reduce weaving and merging

What still needs to be done: In the next few months, work will include: median barriers, pavement grinding, slope paving, metal beam guardrail installation, outside shoulder work on southbound I-5, irrigation and landscaping, striping, signage installation and dyke construction.

What to expect through April 2015: While we finalize the improvements, you can expect temporary lane and ramp closures and a small number of full freeway closures (one direction only) for overhead signage work late at night when traffic volumes are
low. The southbound I-5 Branford Street on-ramp will reopen in April 2015.

Stay informed: Information about closures and project updates will be provided in Caltrans’ weekly motorist advisory and posted on To receive the weekly advisory in your inbox, visit and submit your email address.
