The City has been advised by Metro of upcoming major construction work activities in the remaining eastern areas of the I-105 corridor, which includes the conversion of the existing High Occupancy Vehicle (HOV) lane, or carpool lane, into two Metro ExpressLanes in each direction on the I-105.

As part of the I-105 improvements, work activities for the start of construction in the Segment 3 area, between I-710 and Studebaker Rd near the I-605, are anticipated to start in September 2026. 

In preparation for major construction, crews will begin several activities throughout September, including temporary ramp pavement work, freeway restriping, concrete barrier installation, and tree and vegetation removal.   The start of major construction is anticipated to start in late September which will include work activities such as retaining wall construction, roadway pavement improvements, and drainage system upgrades.

Construction Activities

Temporary ramp pavement construction

Early September 2026 (Day and nighttime work activities)

Work at the Paramount Eastbound on-ramp and Westbound off-ramp, and Lakewood Eastbound off-ramp and Westbound on-ramp to support future long-term construction. The work includes temporary re-stripping of ramps and concrete barrier installation. 

Freeway restriping, concrete barrier (k-rail) installation, and outside roadway grinding work

Mid-September 2026 (Late nighttime work activities)

Temporary long-term re-stripping of lanes and concrete barrier installation to establish work zones along the corridor to support future long-term construction. Traffic lanes will be re-striped to the existing lane configuration of one HOV lane and three general purpose lanes in each direction. 

Tree and vegetation removal

Late September 2026 (Day time work activities)

The removal of trees and vegetation along the I-105 corridor will be performed as necessary at those locations to support future construction between Garfield Ave and Lakewood Blvd in both directions. Upon completion of the project landscaping will be restored with new trees and vegetation. 

Start of major construction

Anticipated to start late September 2026 and continuing through 2029 (Day and nighttime work activities)

Construction includes new retaining walls and roadway pavement improvements. In addition, work related to drainage system upgrades will be performed.

What to Expect

• During construction, nighttime intermittent freeway lane reductions and ramp closures are necessary to safely perform work activities. Consecutive ramps will not be closed at the same time. 
• Most day-time work activities will be conducted in work zones behind concrete barriers, not resulting in any closures along the freeway. 
• Construction for Segment 2, between Central Av and I-710, is anticipated to start in Fall 2026. 

Please note that work schedules are subject to change based on the progress of work and weather conditions.
