Construction efforts continue on Segment 3 of the North Douglas County Transmission Project. Please be aware of several road impacts in the area over the next several weeks.

Road restrictions are expected on Military and Blair High Road during daytime hours Monday through Friday, 11/9/2026 through 11/13/2026. There will be no restrictions in this area on Saturday and Sunday. Restrictions will resume on Monday, 11/16/2026 through Friday, 11/20/2026, on Blair High, Military, and Irvington Roads. All work will be performed during daytime hours between 9am -3:30pm.

From Nov. 22 – Nov. 24, nighttime closures may be in effect on Sprague Street and Maple’s Northbound onramp to I-680, so please use caution.

When detours are necessary, motorists may be directed to alternate routes. Motorists are encouraged to allow extra travel time, follow posted traffic control devices and directions from law enforcement and traffic control workers, and reduce speeds when traveling through work zones.

OPPD appreciates the public's patience and cooperation as crews complete this important infrastructure improvement.

*Please note, timing is subject to change based on weather or construction conditions. 

Progress continues on the construction of segment 3 of the North Douglas County Transmission project. As part of this work, the team begins to install the overhead transmission wires, so there will be a need to temporarily close Interstate 680 overnight on Sunday, November 1. The following week through Nov. 5, night work will continue on and near Interstate 680. We do not anticipate additional road closures, however, lane restrictions and traffic control is expected.

To reduce impacts on daytime traffic, all work will take place between 10 p.m. and 5 a.m. Construction activities may require temporary lane closures or brief traffic stoppages to provide a safe work area for crews. Traffic control or signed detours will be in place when necessary to safely route traffic around active work areas.

Progress continues along Segment 2. OPPD's distribution contractor, Watts, is wrapping up efforts in the western section.

Transmission construction is underway on Segment 3. In addition to structure wreck-out and wire removal, crews were busy constructing a transmission pole foundation near I-680 and Maple St. The foundation has the largest diameter in OPPD's service territory at 14 feet wide and 68 feet deep. It will support the largest style of transmission structure in OPPD's service territory. The structure needs to be so robust because it supports two spans of more than 1,000 feet where the conductor crosses both I-680 and Maple St.

OPPD is relocating distribution lines along Segment 2 of the North Douglas County Transmission Project. This work is expected to continue through the end of October.

Distribution lines are smaller than the large transmission lines, which will be replaced later. Most of this work will consist of moving existing above-ground distribution lines underground and reconfiguring the equipment on existing above-ground pole structures.

This work is necessary to move forward with our larger transmission line rebuild project and will improve the resilience and reliability of the electrical grid in the areas where the work is taking place. OPPD's right-of-way agents will reach out to directly impacted property owners with more detailed dates and times for construction at individual properties.

When relocation of distribution lines in the area begins, you may see crews drilling and boring routes along property boundaries, installing new pad-mounted electrical equipment, and altering the configuration of existing above-ground distribution poles. Our contractors may use trucks, drills, boring rigs, excavators, loaders and lifting equipment to install the new lines.

Contractors that you may see working with OPPD include:

Upon completion in October, OPPD and our contractors will perform cleanup, some property restoration and energize the lines. Please note that OPPD and its contractors may need to maintain access to directly impacted properties until the separate transmission line replacement portion of the project is fully completed in May 2027.

Construction on Segment 1 is now complete.

Construction is expected to begin after the July 4th holiday on Segment 3. Although we've been working on the smaller distribution lines and tree clearing in the area, this construction will include installing new foundations, poles and high voltage transmission lines.

This work will take place at various times. Still, you will see OPPD and our contractors, Brink Constructors and Dietzel Enterprises, as work progresses. 

We recognize this work may cause some inconvenience, and we appreciate your patience and understanding as we work to improve our infrastructure. Safety is a priority. We’re asking our neighbors to be aware of construction activities around their property and to avoid entering active work sites. It’s essential to allow sufficient space for field crews and their equipment.

OPPD is finishing the tree removal process and will soon begin the distribution line relocation phase of Segment 3 of the North Douglas County Transmission Project. We anticipate beginning the relocation of distribution lines in early March and finishing in April. Note that these are smaller than the large transmission lines which will be replaced later. Most of this work will consist of placing existing above-ground distribution lines underground and reconfiguring the equipment on existing above-ground pole structures.

This work is necessary to move forward with our larger transmission line upgrade project and will improve the resilience and reliability of the electrical grid in the areas where the work is taking place. OPPD's right-of-way agents will reach out to directly impacted property owners with more detailed dates and times when construction will be happening at individual properties.

Contractors that you may see working with OPPD include:

We anticipate the distribution line portion of construction in the area to be completed by the end of April 2026. Upon completion, OPPD and our contractors will perform cleanup, some property restoration and energize the line. Please note that OPPD and its contractors may need to maintain access to directly impacted properties until the separate transmission line replacement portion of the project is fully completed later in 2026.

OPPD is in the pre-construction stage for the North Douglas County Transmission Project, and crews will continue clearing trees and brush from the transmission line easement areas as they prepare the transmission corridor along Segment 2. This work will occur at various times. You will continue to see OPPD and our contractor – Hughes Tree Service and Asplundh – as work progresses.

Safety is a priority. We kindly ask you to be aware of activities happening around you. Please do not enter active worksites and allow plenty of space for field crews and equipment. Thank you for your patience as we make these investments to support reliability and growth across the district.

Construction on Segment 1 of OPPD’s North Douglas County Transmission Project is scheduled to begin Jan. 26.

Crews will begin building the transmission line along State Street, between 114th and 140th streets. Construction includes installing new foundations, poles and high-voltage transmission lines. OPPD has already relocated smaller distribution lines in the area. OPPD anticipates completing this segment in June 2026.

OPPD is moving into the pre-construction stage for the North Douglas County Transmission Project, which will improve the electric transmission network to serve increasing demand by all customers. In this next stage, crews will begin preparing the transmission corridor along Segment 3. Crews will begin to remove trees and brush in the Sunny Slope neighborhood beginning on January 12. This work will occur at various times. You will continue to see OPPD and our contractor – Hughes Tree Service and Asplundh – as work progresses.
