We will update our 605-Katella Project page when we get updates from the OCTA.
Please always check their website for the latest information on closures and detours.
Crews completed sawcutting and restriping lanes in preparation for the
northbound I-605 on-ramp realignment. In the coming weeks, nighttime closures on the on-ramp are anticipated as crews remove existing guardrails and roadway pavement to make room for construction of a Mechanically Stabilized Earth (MSE) wall along the ramp. Motorists may notice minor traffic shifts once this work is completed.
Upcoming Closures
Please plan ahead and expect delays during these times. The following closures are expected to be in place nightly from 9 p.m. to 7 a.m., weekday evenings:
Outside lanes on eastbound and westbound Katella Avenue/Willow Street, at least one lane will be open to traffic at all times
Outside lane on northbound and southbound I-605 at Katella Avenue/Willow Street; at least three lanes will be open to traffic at all times

Ever wonder why the I-605/Katella Avenue Interchange Project is so important?
This project will improve travel for drivers, bicyclists, and pedestrians
by:
- Modifying northbound and southbound ramps at Katella Avenue
- Adding Class II bike lanes in both directions
- Enhancing sidewalk connectivity between Coyote Creek Channel and Epson Way
- Constructing ADA curb ramps with new signage and
crosswalks
