Nighttime Closures for Overhead Sign Structure

WHAT: Crews are expected to install overhead sign structures along northbound I-605. This work will require nighttime closures of:

• Northbound I-605 two outside lanes
• Northbound I-605 straight off-ramp to eastbound Katella
• Northbound I-605 loop off-ramp to westbound Katella

WHEN:Nighttime work is scheduled to begin as early as Tuesday, July 28, and Wednesday, July 29, from 10 p.m. to 5 a.m.

Additional nighttime work is anticipated throughout the month of August. More information will be shared in future communications as schedules are finalized.

Eastbound and Westbound Katella Avenue

Crews continue working behind k-rail to construct a new sidewalk and bike lane along eastbound and westbound Katella Avenue between I-605 and Epson Way. This week, crews are expected to place curb and gutter and install pipe along both westbound and eastbound Katella Avenue.

This work may be loud. The schedule is subject to change due to weather or unforeseen operational issues.

Long-Term Ramp Closure Coming Soon!

In early August, crews are expected to reconstruct and realign the northbound I-605 straight on-ramp, which will require a 10-day closure of the ramp. Additional details will be shared in future communications.

This work may be loud. The schedule is subject to change due to weather or unforeseen operational issues.

Sidewalk Access

The sidewalk along eastbound Katella Avenue is open and available for pedestrian use. Construction activities are occurring behind k-rail barriers and do not affect access to the sidewalk. The westbound Katella Avenue sidewalk remains closed while crews continue construction activities in the area.

This work may be loud. The schedule is subject to change due to inclement weather or unforeseen operational issues.
