Construction Activities

Happy Thanksgiving

In observance of the Thanksgiving holiday, there will be no construction activities or closures from Wednesday, Nov. 26. to Sunday Nov. 30. Construction will resume on Monday, Dec. 1.

Upcoming Realignment and Traffic Shift on Northbound I-605 On-Ramp

Crews are expected to realign the on-ramp to create a workspace for a Mechanically Stabilized Earth (MSE) wall, which will include filling the embankment, pavement work, restriping, and placing temporary concrete barriers. This work will occur nightly from 9 p.m. to 6 a.m. beginning as early as Monday, Dec. 1, and is anticipated to take about one week. Following this work, motorists will notice a minor traffic shift on the on-ramp.

Sidewalk Access

While the sidewalks on both eastbound and westbound of Katella are under construction, pedestrians can use a protected walkway on eastbound Katella, which will serve as a temporary pedestrian detour route.

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